Introduction

House A House B

Introduction

The Arbeitsbeft Holzbau is intended as anaid to all those working in the field of con-struction. However, it is neither a con-struction manual nor an encyclopaedia ofmaterials. It aims to show the relationshipbetween design, detail work and the builtproduct. What has emerged is a veryhandy book which summarises, in a user-friendly manner, all the material found inoffices and enterprises that deals withbuilding with wood. To avoid the selectionpresenting here falling prey to rapidobsolescence and, above all. prematureobsolescence, it has been limited tobasic designs and proven materials.

Part 1The first part provides an overview of fheexemplary use of building components,component layers and building materialsand their integration into the overall struc-ture of two prototypical limber houses ofdifferent design. Questions concerningbuilding physics, such as heat, andsound insulation, vapour and fire protec-tion, draught proofing and jointing arebriefly explained and presented ingraphic examples of details and jointstypical of wooden construction.Two simple, common types of terracedhouse have been designed and con-structed to illustrate the interconnectionsand the problems. Common to both typesis the relatively low roof pitch permittingthe use of light roofing materials, Bothhouses can be heated with gas.

House A\sa craft-built timber-frameworkhouse standing on a cellar, its lattice-work walls rest on the cellar walls and thefloor above the cellar and bear a woodenjoist ceiling as well as a doubly supportedroof structure which has not been fittedout. The distance between the post axesand the ceiling joists is 125 cm, making ita multiple of the module of 62.5 cm,which many of the building materialsobserve, The disadvantage of usingthicker boarding on the visible joists hasto be weighed up against the spatial (hallwidth, cubic measure) and the designadvantages (door and window openingswithout trimming). It could be reduced to83.33 cm (250 cm: 3).To improve the dimensions of the roofoverhang at the eaves and the verge, therafter spacing between was halved to62.5 cm.

The greater part of House B is designedto be produced in the workshop andassembled from prefabricated wall ele-ments, floors and a roof on a floatingfoundation, assuming that the subsoil issuitable. The roof has been fitted out andintegrated into the interior.The design is based on a dimensional co-ordination of 62.5 cm, corresponding tothe basic elements of panel constructionsuch as the panel dimensions of the ply-wood, chipboard and, above all, plaster-board / gypsum-fibre board. This dimen-sional co-ordination has proven to be auseful standard for partial and full prefab-rication.

The development of the skin and itsmaterial implementation has been exe-cuted in accordance with the differentgoals of the two projects.

Part 2The generic terms of building materialsand joints and fasteners have been ital-icised in the commentary on the details.In part 2 they are listed in the sub|ectindex under the marked generic termalong with products, specifications andmanufacturers.

Part3The brief illustrated documentation of thenine completed projects is intended toconvey an impression of the diversetypes of wooden buildings, showing thedesigns chosen, the specific ways inwhich the details have been elaborated,and the materials used.

Part 4The appendix contains technical informa-tion, a summary of the pertinent guide-lines and standards together with a bibli-ography and a list of manufacturers, alsoincludes cross-references that allow read-ers to follow the path from the manufac-turer to the product and its use and viceversa, as well as a subject index and listof names,

House AExterior Wall, Plinth

House AInterior Wall, Floor above Basement

Under DIN 18195, and to ensure that thewood is protected, a plinth height of30 cm must be observed. Although aplinth can be lower in principle, specialmeasures must be taken where this is thecase, for example: a roof overhang, off-sets, weather-protected sides, andcoarse gravel strips to reduce watersplashing.

The perimeter insulation of the exteriorbasement wall is covered on the outsidefor aesthetic reasons and to offer protec-tion against any mechanical damage, forinstance, with a fibre-cement slab.

Lib

The perimeter insulation and the wallstructure must be made to harmonise withone another at the transition of the perim-eter insulation to the facade. The cross-section for the ventilation must not beobstructed in any way. If banked-upcoarse gravel is used to push the lowerpanel edge against the insulating board,the fibre-cement slab need only be fas-tened with a batten along its upper edge.The vertical panel joint must be executedin a way that prevents moisture fromseeping behind the panel.

U c

The wooden sill plate must take up thetolerances of the concrete floor above thebasement, The joint is sealed with high-expansion cement mortar. The wooden sillplate must be impregnated both to pro-tect it and insulate it from the concretefloor. Chemical wood preservative is notnecessary if timber species with a highresistance class are used. To attach thebar-reinforced sill plate to the floor, theplate is drilled through and then anchoredwith a heavy-duty bolt, taking care that asafe distance is maintained to the edge ofthe concrete.

(Alternatively, the sill plate can be fixedwith an angle attached to the side or witha ragbolt cast in concrete,)

d

The exterior wall construction consists of12 x 12 cm posts with a unit spacing of125 cm, and a vertical or horizontal inter-mediate structure adapted both to thesubstructure of the exterior and interiorlining and to the format of the thermalinsulation. Insulation can be applied panelor roll form, or sprayed on in flake form.Flakes should only be injected if there aresealed chambers between the posts.A softboard is fixed across the entirebearing structure to reduce heat lossthrough the structure and the joints. Thepanels, to which battens can be directlyfixed, are rebated to provide draught-proofing.

If a fibrous insulating material is used.vertical battening and some kind ofdraughtproofing will be necessary.

The ventilation cross-section between theweatherboarding and the inner board issufficient to ensure ventilation of the exte-rior skin.If more resistant and well-patinated woodspecies such as larch, cedar and Doug-las fir are used, the surface boardingneed not be treated. However, this will notprevent the wood from greying, which isharmless in any case. If other woods areused, a weather-protective layer, such asa glaze or a coat of paint, will be neces-sary - depending on the resistance class.

f

The interior lining comprises verticalmatchboards attached to a horizontal bat-ten substructure. If the post spacing is125 cm, the substructure should have across-section of at least 30 x 50 mm or -better s t i l l -40x60 mm.In this area, dimensional tolerances canbe compensated for and electrical cableslaid. However, there is too little space tofit electric sockets here without piercingthe vapour retarding layer inside the ther-mal insulation. As it is difficult to mountconnections on the vapour retarding layer,electric sockets and switches should beinstalled on the Interior walls wheneverpossible.

•The load-bearing interior walls also con-sist of 12 x 12-cm post with horizontalrails. The sill plate must be anchored inthe same way as the exterior wall to thefloor above the basement. It is not neces-sary to observe minimum distances (thestairwell being an exception) between theheavy-duty bolt and the concrete edgehere.

When constructing the floor, care must betaken that the sill plate is high enough toensure that the floating screed terminatesat an edge insulating strip. Although flushskirting boards offer a more elegant solu-tion, they are also more expensive.

Dh

The electrical installations are routedthrough the cavity in the interior wall,which is soundproofed with a mineral- orcoconut-fibre panel. If stable load-bearingstructures are used (for example, solidstructural timber with additional horizontalrails), the boarding can be mounteddirectly. Alternatively, plywood or OSBpanelling can be used.

House AExterior Wall, Floor/Ceiling, Window

The window, which is mounted flush withthe wall and tixed to the rail at sill levelwith a metal angle, provides a simpletransition to the overlapping verticalweatherboards. Care must be taken thatthe angle is mounted on the bearingstructure in front of the soft particleboard.The draughtproofing can be fixed to a bat-ten beneath the outer window frame.A similar procedure is adopted on theinside when connecting the vapour retard-ing layer to fhe prefabricated windowframe, which is fixed to the outer frame.Before the vapour retarding layer ismounted, the joint between the windowframe and the bearing structure must becarefully filled out or foam-filled with insu-lating material.

Joint sealing tape must also be applied toensure that the window is airtight.In January 2002, the Ordinance onEnergy Saving came into effect, whichtightened up the requirements for exteriorwalls. Under the ordinance, these wallsmust be constructed and verified astotally draught-proof enclosures. Thisapplies, in fact, to all junctions, especiallyfor those at the window surrounds.

._. b

The exposed transverse joists in the floorsare fixed to the posts with galvanisedsteel sheet Joist hangers. To ensure thatvapour is fully retarded, a section of foil -to which the vapour retarding layer is sub-sequently attached - is attached to thebearing structure when the beam is fixed.A board is fitted between the beams to abatten substructure to create a flush con-nection to the interior wall cladding andcover the underside of the joint betweenthe panelling and the bearing structure.This step is necessary as swelling maycause movement in the panelling.To prevent airborne noise entering at theedge of the ceiling, the joint between thefloor and the wall must be carefully filledin with insulating material.

As a structural grid of 125 cm has beenchosen for the building, tongued-and-grooved floor covering is required. A floorcomprising plain floorboards on timberbearing strips laid loose and filled withinsulating material will suffice for adetached house. If prefabricated parquetor sheet flooring is preferred, it is advisa-ble to lay the flooring on a load-bearingsurface of ready mixed dry screed. Air-borne-sound insulation can be optimisedby putting loose fill beneath the impact-sound insulation or by ballasting the floorstructure with, for example, paving flagsattached with adhesive to give a shear-resistant bond.

d

The joint between the lintel beam and thedoorframe is filled in with insulating mate-rial to improve the sound insulation of theinterior wall. The rebate in the solid doorframe not only seals the joint with the inte-rior-wall lining, but also creates a harmo-nious transition between the door andwindow flashing on the one hand, and theinterior boarding on the other.

De

The fioor joists rest on the head of theinterior load-bearing wall, The spacebetween the joists is sealed with an addi-tional rail at the same level as the joists.This area can now be covered with aboard, as was the case with the exteriorwall.

f

The solid door frame is connected to thefloor by a threshold, a measure which notonly ensures greater stability when trans-porting the door frame, but also makes itpossible to lay the flooring without havingto fit it into the door reveal.To provide adequate impact-sound insula-tion here too, an insulating strip is fittedbetween the threshold and the flooring.The joint between the threshold and theplanks is filled with a cork strip to absorbany movements in the materials.

•A sheet-metal covering joined with lockeddouble-welt standing seams and laid on aseparation layor has been chosen for theroof covering. If the separation layer is toserve as sheathing, a more resistantmaterial, appropriately laid, should beused. The rafter spacing of 62.5 cm cor-responds to the support-grid of 125 cm.Instead of planed boarding, a panel ofwatertight adhesive bonded plywood hasbeen used, which allows the roof-skinoverhang to be extended over the ends ofthe rafters at the eaves. A chemical woodpreservative, as required under DIM 68800, is unnecessary.As the overhang is to be fixed to the raft-ers, its size must be adapted to the lengthof the gutter bracket. The panel widthsare obtained by dividing a standard panelin equal parts to avoid waste, for exampleby quartering a 125 cm-wide panel.

b

The floor beneath the roof void isdesigned in the same way as the upperfloor, whose joists are connected to theposts by beams. A carpenter fits thevapour retarding layer and the thermalinsulation in sections, connecting themwith the ceiling boarding to the roofboarding of the profiled planks. They arethen covered with a water-repellentdraughtproofing designed to allow diffu-sion. The roof overhang on the gable sidecalls for a relatively large cross-sectionfor the projecting eaves purlins. Thedraughtproofing is attached to the eavespuriin.

nc

To ensure that the roof edge is kept asnarrow as possible, the seam at the vergeis bent over and bonded to the overhang-ing roof boarding to form a drip batten.The building's low height allows for asheet bay width of 62,5 cm and therebyharmonises the locked double-welt stand-ing seams with the rafter arrangement,which corresponds to half the structuralgrid.

d

In the gable area, the exterior wall struc-ture only extends as far as the fioorbeneath the roof void. The roof void is notinsulated to the outside. In order to fit theinsulation, the draughtproofing and thevapour retarding layer ai the transition fromthe wall to the ceiling, an edge beam hasbeen fitted to the roof boarding so thatthe individual insulating layers can beattached to both its long sides.

The vertical exterior boarding extends asfar as the lower edge of the roof board-ing; it is screwed to a plank running alongthe edge rafter on the lower side of theroof boarding. At this edge, air from boththe ventilated roof and the wall construc-tion can escape through the ventilationcross-section of the overlapping verticalweatherboarding.

f

A vertical plank, fixed to the side of theposts, will provide sufficient support forthe load-bearing roof boarding at thegable wall.

House AExterior Wall. Services Installation Shaft

House AParty Wall

The exterior corner of the overlappingvertical weatherboarding is easily madeby connecting the window boards to cre-ate a butt joint. The boards are fixed tothe horizontal battens with nails or screwsof stainless steel (they may be galvanisedonly in exceptional cases! to avoid corro-sion stains on the boarding, Each boardis fixed separately to avoid tension due toswelling and shrinkage.The joint can be made airtight by overlap-ping or bonding the boards at the corner.

Normally, boards of equal width are usedfor the overlapping vertical weatherboard-ing, As the outer boards overlap thosebeneath them - approx. 25 mm on eachside - the boards appear to be of differ-ent widths. This system allows for differ-ences in spacing between the boards,obviating the need to use door and win-dow flashings of special widths. It isessential that the facade be plannedcarefully and all measurements be pre-cisely attuned to the positioning of theboards.

When windows are installed flush, theymust be attached to the side of the outerframe in such a way that the overlappingweatherboard seals the joint between theouter frame and the wall. There is noneed for the casement to be rebated atthe side. The draughtproofing, insulationand the vapour retarding layer are con-nected to the wall structure in preciselythe same way as the window to the linteland the parapet beam.

For the services shaft, a substructurecomprising 6 x 20 or 8 x 20 cm posts isnecessary. Optimally, it is constructedhalf a grid space in the exterior wall toreduce the span of the planking. Ceramictiles are bonded to the gypsum fibreboardor impregnated plasterboard (identifica-tion colour: green).

When connecting the sanitary fittings, thelocation and dimensions of the posts andrails must be taken into consideration, [fthe rib spacing exceeds 40 cm, two lay-ers of plasterboard will be necessary.

In the area of the shaft, the vapour retard-ing layer is fixed to the inside of the bear-ing structure to ensure that the servicelines do not unnecessarily penetrate thevapour retarding layer,The floor structure continues through theservices shaft. If lines run vertically, theceiling boarding must be drilled or cut outto the size of the conduits.

Dd

According to the building regulations andDIN 4102, a party wall must comply withfire resistance class F 30 B on the roomside and F 90 B in the cavity.These requirements are fulfilled on theinterior by using a single layer of plankingwith 12.5 mm fire-resistant plasterboard.For the exterior, two-layers of plankingwith fire-resistant plasterboard ( 2 x 1 8 mm)are required. In the case of terracedhouses, this requirement applies to bothbuildings. During construction, the side ofthe building must be planked before thewall is erected,

The expansion joint between the housesis not filled for reasons of sound insulation.A vapour retarding layer and draught-proofing are not necessary in the partywall. All things considered, this type ofwall structure is a relatively costly andtime-consuming affair. In timber construc-tion, however, there is no recognisedalternative to this approach.

Under the building regulations, a terracedhouse is a low-rise building whose partywalls are constructed like compartmentwalls. In the cavity, the F 90 planking canend at the inside of the overlapping verti-cal weatherboarding. The boarding venti-lation space must, however, be sealedwith a non-flammable insulating materialsuch as mineral fibre extending at leastthe width of the party wall. The boardingcan be continued uninterrupted acrossthe expansion joint.

House BExterior Wall, Plinth

House BInterior Wall, Sole Plate

Before constructing a floating foundationwith a load-bearing reinforced concreteslab on frost blanket gravel, it is first nec-essary to carry out preliminary investiga-tions to determine the soil type and estab-lish its bearing capacity. A rapidly drain-ing, concentrated soil with a good bear-ing capacity is absolutely essential. Thetop layer of soil must be replaced by alayer of clean gravel approx. 40 cm deep,which is then carefully compressed andcovered with a sub-base of 5-10 cm-thick grade B5 concrete on which thereinforced floor slab is cast.

Db

On the interior, the floor slab must bethermally insulated beneath the screed.The transition to the exterior wall is a weakpoint. This problem can be overcome(and the planned insulation standardmaintained) by fitting impervious thermalInsulation to the front side of the sole plateand covering the insulation either with aflat fibre-cement slab or concrete roofingtiles.

Prior to installing the prefabricated exte-rior wall elements, a sill is put in place,aligned, underlaid and fixed to the con-crete slab with either lug angles and dow-els or anchor bolts. The space betweenthe sill and the floor slab is filled with high-expansion cement mortar. Since it is par-ticularly exposed to hazards, the sill mustbe protected to meet hazard class 2requirements. Alternately, a very resistantwood species can be used, which willeliminate the need for chemical woodprotection.

The damp-proof course on the floor slabis first bonded or welded to the sealbeneath the sill. Then the plasterboardlining is attached to the elements, whichare initially left unclad on the interior.

d

A permit must be obtained from the build-ing supervisory authorities before the pre-fabricated insulated wall elements can beerected. Although these elements aresubsequently panelled on both sides(clad elements), with most wooden con-structions it is customary to panel themwith plywood sheeting or plasterboard onthe outside only at first, and to leave themunclad on the room side until they have

been fitted to the structural timbers (soft-wood timbers measuring 6 x 12 to 6 x16 cm, depending on the insulationstandard).The above procedure makes it easier tofix the sill to the floor and install the wallelements.If the panelling is to be used for reinforce-ment, permission must first be obtainedfrom the building supervisory authorities.The elements are screwed to the con-struction, which is then sound insulated,vapour retarded and lined on the interiorwith plasterboard or wood-based panels.

If the interior panelling is to be attacheddirectly to the structural timber elements.great care must be taken when planningthe services, particularly the electricinstallations. If there is no alternative toconnecting sockets to the exterior wall,protected sockets with an adhesive edgemust be used. The sockets must be care-fully bonded to the vapour retarding layerand provided with external insulation.

The height of the elements correspondsto that of the room(s), which, in turn, mustcomply with standard board dimensions.The element lengths partly depend on themethod of transport and assembly used.Elements can extend the entire width ofthe house.

The interior wall elements, which mustcomply with the standard dimensions ofboard materials and construction timbers,comprise structural limbers made of soft-wood and measure 6/12 cm (centre dis-tance = 62.5 cm). Like the exterior wallelements, they should initially be panelledon one side only. Once they have beenconstructed and installed, they should beclad with plasterboard or wooden panels.If the cavity between the structural timberelements has not been completely filledwith expanded mica, cellulose flakes, etc.,it should be filled with mineral or coconut-fibre sound insulation at least 30-40 mmor - preferably - 60 mm thick.Higher sound-insulation values can beobtained by applying double panelling orfitting additional "floating" panel claddingwith flexible wall connections.

f

Appropriately bonded wooden panels orimpregnated plasterboard (identificationcolour green) must be used in the humidrooms. Gypsum fibreboard has the advan-tage of not requiring additional treatment.Two layers of gypsum fibreboard will benecessary if humid rooms are to be tiledor the spacing between the structural tim-bers exceeds approx. 42 cm.

The shrinkage ratio of the noggings mustbe taken into account when attaching thepanelling. Owing to their cross-section,this ratio is small and can be reduced stillfurther by using pre-dried wood.

22 23

Page 12: [Architecture eBook] Timber Construction - Detail Praxis

House BExterior Wall, Foundation

A different and perhaps more consistentapproach to wood construction as a "dry"construction method is to use a floor con-struction comprising structural timber ele-ments and with excellent thermal insula-tion, and to panel them on both sides.(These elements have dimensions ofapprox. 6 x 20 cm, determined staticallyand in accordance with insulation stand-ards.) The rising walls are connected tothe aligned and fixed floor elements.Cemented chipboard and fibrated concreteslabs make suitable underside panels.

The cavity between the infilling and theunderside of the elements must be per-manently ventilated. This can be done byinstalling correspondingly large gratedopenings on both sides of the terracedhouse.

Floating dry screed composed of wood,plasterboard, or gypsum fibreboardpanels should be installed as a dryconstruction.The PE-foil under the impact-sound insu-lation serves as a vapour retarding layerand simultaneously provides draughtinsulation.

24

House BInterior Wall, Foundation

Beneath the interior walls, there is noneed for frost-proof foundations or forcontinuous footing concreted to the soil orplanked. The position of the footing isdetermined by that of the floor elementsand the load-bearing interior walls.The floor elements should be formed as aplate and anchored to the foundation withauthorised dowels or connection anglesand stone bolts. AW 100 plywood strips orhigh-expansion cement mortar can beused to equalise out any unevenness. Avapour barrier of, say, polymeric bitumenor plastic sheet is fitted between the floorelements and the foundations to preventany damage through moisture. The abut-ting joint between the elements must besealed with insulating strips and sealingtape,

25

Page 13: [Architecture eBook] Timber Construction - Detail Praxis

House BExterior Wall, Floor/Ceiling, Window

The wall elements are held together by,and aligned with, the upper headpiece.The floor, which is composed of gluedlaminated beams or glued laminated tim-bers, is fitted and bolted in elementwidths of between 60 and 250 cm(beams) or 62.5 and 100 cm (timbers).Mounting and shrinkage must be takeninto account when choosing the width.During the construction phase, the wood- especially the solid elements - must beprotected from the weather at all times toprevent damage through moisture andswelling.

If necessary, diaphragm action can beensured by joining the elements to makethem shear-resistant.

u b

To ensure that the light, effectively insu-lated wooden waif fulfils its function, thevapour retarding layer must be connectedto the wall at the floor edge in a way thatallows for subsequent inspection. Corre-spondingly long sections of flexible plasticsheeting that allow for diffusion must bewrapped round the end of the floor andfixed on the upper side of the floor to thevapour retarding layer sheeting of theinstalled wall elements.

The selected assembly system and pointin time when the exterior wall cladding isinstalled determine whether the surface-finished windows are assembled in theworkshop or on site, and whether they areinstalled with or without glazing.The windows must be fitted to the struc-ture with a section of vapour-resistant,flexible plastic that is fixed to the windowframe.

The joint between the lintel and the win-dow frame performs a vital function dur-ing installation in absorbing tolerancesand movements. It should be filled withan insulating material (mineral fibres, min-eral wool, sheep's wool, etc.) and sealedwith a pre-compressed seating tape orpermanently elastic sealing material. Thestringent requirements of the energy con-servation regulations must be observed(see also p. 14a).

d

The ceiling's structural connection to theinterior walls corresponds to that of theexterior walls. The problems related tofitting the vapour retarding layer anddraughtproofing do not apply here.

The joint between the lintel and the door-frame is constructed in the same way asthat of the window (see item c). Therequirements of building physics con-cerning heat, vapour and draughts, whichpresent considerable practical problems,do not apply here.

f

The floor structure, which is composed ofparquet, dry screed and impact insulation,has been made 3 cm thicker than usual toinclude a services shaft which, in turn,accommodates the larger number ot lineslaid along the floor/ceiling. The problemof power-supply lines crossing oneanother can only be surmounted by care-ful planning.

Even with such a relatively "complex"ceiling structure, additional measures canbe taken to improve airborne-sound insu-lation by, for example, using "sand hon-eycombs".

aThe roof floor of glued laminated beams orglued laminated timbers is fitted to thesupport and screwed to the sill. As withthe floor, a section of plastic sheet thaiallows diffusion is guided around theheadpiece of the roof floor and fixed tothe floor vapour retarding layer. The sheetends must be either bonded together orwell overlapped and fastened.

b

The height of the cross rafters is deter-mined by the thickness of the thermalinsulation.Covering the insulation with vapour per-meable, water-repellent paper, or withplastic sheeting displaying the same quali-ties, ensures that any precipitation (rain,drifting snow...) or "secondary" meltwater(changes in weather or cold night air thatcools the underside of the non-suckingroofing material) can drain off, and thatthere is no reduction in insulation value.Ventilation and drainage are ensured bycounter battens and a triangular cleat ofperforated plate, which is fixed to theeaves flashing with tingles.

The eaves flashing rests on a plywoodstrip, for which the cross-rafters are cutout. II is advisable to bolt the flush coun-tersunk gutter hanger onto a continuousfascia.

The dimensions and spacing chosen forthe rafter-supporting purlins depend onthe corrugated sheet roofing used.

The width of the insulating panels mustbe greater than the clear spacing of thecross rafters to accommodate the slightlycompacted thermal insulation installedbetween them, which has to compensatefor any wood shrinkage.The division of the substructure intocross-rafters and counter battens ensuresthat the vapour-permeable protectivelayer is level and remains securely fixed.

The main goal here (depending on thethermal-insulation requirements for theroof) is to ensure that the continuous raft-ers do not create a thermal bridge. Thiscan be avoided by installing a secondinsulating layer, as shown in the examplehere. Another solution is to place insula-tion beneath the foil between the horizon-tal counter battens, or to install continu-ous bituminous fibreboard decking, whichsimultaneously acts as a protective layer.

The efficiency of the various insulatingmeasures and the utility of a houselargely depends on whether the protec-tive layers, which take the diverse loadsimposed on a building (thermal, moisture,air), can be applied consistently andsafely to all connections. They must alsobe open to inspection.

The storage capacity of the heavy roofmembers improves thermal protectionduring the summer.

•If the substructure unit spacing of62.5 cm is observed, the plywood panels(which are generally 125 cm wide) can bescrewed in the centre of the panels andat their edges. The width of the coverstrips has to be calculated accurately toensure that the edge spacing of thescrews is sufficient, and to fully cover thescrew heads. Narrower cover stripsshould not be used unless an alternativeway is found of fixing the facing panels(e.g. by screwing them onto more closelyspaced substructure elements) and thepanel edges only has to be cramped bythe screwed-down cover strips.

Although the absence of a visible boltedconnection (with a shadow gap, sealingtape and a correspondingly wide sub-structure) on a smooth large plywoodcladding panel does justice to the mate-rial, it nevertheless exposes the paneledges. This, in turn, makes it almostimpossible to prevent water absorptionand heightens the risk of damage ormovement from swelling and shrinkage.The following protective measures can betaken here: reduce the weather loads,e.g. by circumspect alignment of thebuilding, use large roof overhangs or can-tilevered balcony slabs, and give alledges water-repellent treatment. As theseprecautions were not taken in the exam-ple presented here, a more resistant jointwas chosen and secured with coverstrips.

The elements are jointed at the corner.Although the corner design shown hereis atypical for wooden frame construc-tions, it does make it easier to connectthe elements in an open corner joint.After it has been screwed together, thecorner must be sealed on the outside witha prefabricated, thermally insulated metalangle.

The greater requirements (regardingbuilding physics! placed on the exposedoutside corner mean that considerablecare must be taken when installing thethermal insulation and the vapour retardinglayer. The joint must be completelypacked with insulating material (filling,injecting) and the angle sealed with tape(buthyl, for instance) beneath the overlap-ping joint of the vapour retarding layer(nailed/clamped and bonded).

According to the Building Regulationsand DIN 4102 T-4, party walls must havea fire-resistance class of F 30-B (interior)and F 90-B (exterior). These requirementscan be met using glued laminated beamsor glued laminated timber elements whichare panelled accordingly on the outside(in contrast to trie procedure adoptedfor House A). If this method is chosen,the construction must be inspected anda permit may have to be obtained. Asan alternative to leaving an air spacebetween the party walls, an elastic insulat-ing material could be used here (e.g.building class A, melting point > 1000 °C).

• d

II is necessary to establish the requiredacoustic reduction (required Bw = 57 dBor 67 dB for greater sound insulation).Sound insulation can be improved evenmore with an interior facing shell of plas-terboard panels on spring shackles.

The expansion joint must extend to theouter edge of the exterior wall.The width of the non-flammable backfillinsulation must be established in co-oper-ation with the responsible authority.

UseStructural solid wood is primarily usedwhen the wood used has to fulfil strictrequirements concerning its load-bearingcapacity, appearance, dimensional accu-racy and shape retention. In woodenhouse construction, structural solid woodis used primarily in the construction offully insulated structures.

As the wood has a moisture content of15 ± 3 %, it need not be treated withchemical preservatives.

In both cases, finger jointing is permissi-ble as spring-actuated longitudinal joint-ing. This type of jointing does not weakenthe cross section of the wood and neednot be taken into account during stressdetection.In the case of visible structural solid tim-ber, a heart-free cut is obligatory for crosssections of up to 100 mm. This is madeby removing a 40 mm-thick heart plank, Aheart-free cut is obligatory for all othercross-sectional thicknesses and for theentire range of visible structural solidwoods.

MaterialGlued laminated beams are solid, flat,building elements. They are composed oflayers of boards or planks connected toeach other with nails or hardwood driftbolts. The quality of the original material isnot subject to particularly high minimalrequirements. Laminations of gradesS7/S10 are sufficient. Side boards can beused. Although there are no obligatorylamination thicknesses, the customarysawmill thicknesses of 24-32 mm, or upto 60 mm in special cases, are recom-mended. Boards and planks with thick-nesses between 32 mm and 45 mm areoften used for visible structures.

UseFloors, ceilings, roofs, (both bearing andnon-bearing] can be constructed withglued laminated beams. The individualbeams are used vertically in the wall ele-ments.Additional measures can be taken if dia-phragm action is desired.Solid wooden elements have a far higherstorage capacity and therefore providebetter thermal insulation during the sum-mer months than wooden framework wallconstructions.The individual elements are connectedwith groove-and-tongue joints, rebates orflat steel connections. Swelling andshrinkage must be taken into considera-tion when selecting element widths. Inorder to avoid swelling, the wood must beeffectively we at her proofed to protect itduring transport, storage and installation.

This system, which has a high load-bear-ing capacity, allows for extremely slendercross sections. A variety of compositeconstruction systems involving the use ofconcrete are available on the market.

For invitations to tender and orders:- Manufacturer• Wood species• Thickness/width/length• SurfaceCalculated per m/mJ

ManufactureGlued laminated beams are generallyprefabricated. After the laminations havebeen dried to a wood moisture content of15 + 3% they are levelled, arrangedclose together lengthways, and gluedwith staggered joints in a continuousprocess. Laminations of the same thick-ness and width are used. The couplingforce can be transferred to the laminationjoints by using more nails, or by gluing orfinger jointing. The joint can be strength-ened by using profiled boards on thefaces.

Floor/ceiling openings and other open-ings must be taken into considerationwhen manufacturing glued laminatedbeams.

The elements can be prefabricated inlengths of up to 2.40 m, depending ontransportability. Lengths should notexceed 12 m.

UseUnplaned and planed boards andplanks are used for shuttering, externalcladding and the most diverse areas ofconstruction. When boards and planksare used for structures that have to bedimensioned in relation to load-bearingcapacity, they must meet the require-ments of DIN 1052 and be graded inaccordance with DIN 4074-1. If theboards do not have to perform a load-bearing or reinforcing function, there isno necessity under German buildingregulations to take preventive measuresto preserve the wood.It is advisable to use load-bearing lathingwith a cross section of 30 x 50 mm (mini-mum cross section 24 x 48 mm) to affixthe cladding. These cross sections areavailable as dry wood from trade stores:cross sections with an average moisturecontent of 15 ± 3 % can also be obtainedby invitation to tender.Visible joints and fastenings for externaluse must be made of galvanised steel or- better still - chromium-nickel stainlesssteel.

MaterialFormerly known as core plywood, block-board consists of a core layer of solidwood board-shaped strips that are gluedtogether. The width of the strips variesfrom approx. 24 mm to a maximum of30 mm. A face veneer (three-ply board)or a cross-band veneer and a faceveneer (five-ply board) is fixed to eachside, with the grain running perpendicularto that of the adjacent layer.

Laminated boards are composed of amiddle core of perpendicular rotary-cutveneers (strips) that are glued together.The veneers are 5-8 mm thick. A faceveneer, or a cross-band veneer and aface veneer, are fixed to each side. Thegrain of each sheet runs perpendicular tothat of the adjacent one.All glues with an assured adhesivestrength are permissible.

In the case of blockboard. the gluedwooden core is composed of softwoods(primarily spruce) to ensure a more stableform, whereas softer or harder hardwoodsare generally chosen for cross-bandveneers and face veneers.The same wood species can be used forboth wooden core and veneer plywood,alongside the customary indigenous soft-woods and hardwoods. A number oftropical woods are also used for the coresand for cross-band and face veneers,rounding off the customary indigenoussoftwoods and hardwoods available.

UseBlockboards and laminated boards areprimarily used in the manufacture of furni-ture, as well as in laboratory and stairconstruction. However, they are rarelyused in timber engineering.

ManufactureIn general, 24 mm-thick softwood boardsthat have been carefully dried to a woodmoisture content of approx. 6-8 per centare considered suitable for the manufac-ture of block cores. These boards are cutinto laths with multi-blade circular sawsso that the lath width corresponds to thethickness of the inner core. The laths arethen glued together with casein, poly-vinylacetate or urea-formaldehyde resinsto form boards and pressed.

DIN 68705-4 refers to structural block-board and core-stripe blockboard asplywoods with defined, monitored elasto-mechanical properties. They are used inbuilding construction (e.g. for reinforce-ment).

In the manufacture of the core, rotary cutveneers 5-8 mm thick are glued in layersparallel to the grain to create blocks.These are then sawn at right angles to thelevel of the single plies to make boards.In both manufacturing processes, thecross-band and face veneers are gluedto the inner plies with the same glues andpressed.

MaterialParallel laminated veneer is a multi-plywood-based material. In contrast to ply-wood, its veneers are generally arrangedparallel to the gram and glued watertightwith phenol-formaldehyde resin. If broadwidths are required, plies are alsoarranged crosswise to increase stability.When wood class 100 G veneers areglued together, the single sheets areimpregnated with a wood preservative tofor protection against destructive fungi.

Application(s)Parallel laminated veneer may be used inall areas of work in which glued laminatedtimber is permitted.Owing to the high loads it is permitted tobear, parallel laminated veneer can alsobe used for reinforcing the followingstructural elements:purlins and other girders subject to bend-ing, girders at the point of support, load-bearing plates, connecting plates, etc.

The presence of cup shakes in theveneers makes it relatively easy toimpregnate parallel laminated veneerwith aqueous wood preservatives acrossits entire cross-sectional area. As aresult, it can be used in areas exposedto the weather (e.g. external use for roofpanels).

MaterialParallel Strand Lumber (PSL) consists ofstrands approximately 16-mm wide and3.2 mm thick. These are aligned parallelto the longitudinal axis of the beam andglued with waterproof phenol-formalde-hyde resin. The graded strands are gluedto create 483 mm-thick panels and thensawn into beams.Currently, PSL is only manufactured in theUSA.Paraffin is applied to give the lumber awater-repellent finish.Owing to the natural resistance of the twowood species used (resistance class 3 inaccordance with DIN 68364|, no woodpreservatives are added.

Application(s)Parallel Strand Lumber can be used forall work in which glued laminated timberis permitted unless otherwise certified.Parallel Strand Lumber has maferial prop-erties very similar to those of glued lami-naled timber; its advantages lie in its con-siderable flexural, compression andshearing strengths.The adhesive bond is weather resistant,but weather exposure causes the wood toturn grey.

ManufactureAfter being soaked and steamed, the logsare peeled to create veneers 2.5-3.2 mmthick. The strands are then dried to obtaina9-10 percent moisture content and cutinto 45-260 cm-long strips. After thedefects have been extracted, the strandsare glued with phenol-formaldehyde resinand pressed in continuously operatingpress. Afterward, they are cured in amicrowave process.

The veneer strands are arranged parallelto one another with their ends staggered.During the pressing process, the materialis compressed to increase its raw densityto a value slightly higher (approx. 15 percent) than that of the original wood. Asthere are gaps between the strands, cavi-ties are visible, especially at the ends.The resulting 20 m-long section is thencut to fhe desired lengths.

MaterialOSB (oriented strand board) is composedof aligned strands. Owing to the alternat-ing, cross-alignment of the strands, ori-ented strand boards - like plywood -have mechanical properties.Excellent mechanical properties havebeen obtained (two to three times thoseof normal chipboard types) by machine-cutting the wood parallel to the grain.

A variety of glues is used for bonding:phenol resin, polycarbamide (isocya-nate), MUPF (Kauramin) surface glue,and PMDI core resins. All these resins arewaterproof.

Application (s)Typical areas of application:OSB flat-pressed boards may be used forall work where class 100 wood-basedmaterials are permitted under the localBuilding Regulations.It may be used for panelling, with weatherproofing, the exterior of load-bearing/reinforcing walls.

ManufactureLarge coarse rectangular chips (ca. 35 x75 mm, thickness 0.6 mm) are used tomanufacture OSB boards. The flat chipsare obtained by peeling and crushingveneers or by using a chipper. They arethen sieved, graded, dried, glued, spreadout and aligned. The strands arearranged crosswise in three or five layers,depending on the required board thick-ness. In the case of three-ply boards, thecore (comprising 50 per cent of thewhole) is generally laid crosswise, whilstthe grain of the surface sheets (account-ing for 25 per cent each) generally runsparallel to the machined length. Once thestrands have been aligned, the sheetsare pressed under heat. After they havecooled, they are formatted and ground.

ManufactureIn the manufacture of wood fibreboards,the wood chips are placed in a reactiontank known as a defibrator, steam-treatedand then defibrated mechanically withgrinding plates. This approach primarilyexploits the matting properties of thefibres and their natural adhesive strength.The latter can be increased by addingbonding agents and water-repellents aswell as by thermal and other treatments.The various manufacturing processes dif-fer mainly in the technique employed toproduce the fibrous material and thefibrous mat. These processes are referredto as wet or dry processes, depending onwhether the fibrous material is trans-ported or formed in a wet or dry process.

ManufactureIn the manufacture of extruded particleboards, particles are mixed with a bond-ing agent and pushed rhythmically alonga heated channel by a ram. The cross-section of the channel forming the boardcorresponds to that of the resulting prod-uct. The particles are positioned perpen-dicularly to the board's surface, whichproduces a relatively high shearingstrength at right angles to the surface.Extruded particle boards are made in acontinuous manufacturing processbecause the heating process and the rateof feed are adjusted to the curing time- Asthe particles pass through the channelshaft, they are bonded together to forman endless stream of board that is onlycut into sections after pressing is com-pleted.

Solid extruded boards are produced insingle layers only. Owing to the arrange-ment of the particles, these boards havea lower flexural strength than flat-pressedboards. Extruded particle boards are onlysuitable as cores in composite boards,Tubeboards, whose cores contain tubularcavities, are produced by arrangingtubes parallel to the shaft.

MaterialPorous soft fibreboard is manufacturedfrom spruce, fir and pine pulp in a wetproduction process. Fibre humidityexceeds 20 per cent during the manufac-turing process.The raw density of soft fibreboard liesbelow 450 kg/m;i, making it lower thanthat of medium hard and hard fibreboard.

Application®Soft fibreboards are used as insulation forfloors, walls, ceilings and roofs; they arealso employed as impact sound insulationunder floor screed, dry screed and woodflooring, and as sound absorbing panels.

Depending on the application, the boardsare connected by butt joints, rebate jointsor tongue-and-groove joints. The panelsare loosely laid and then mechanicallyfastened or glued. Special joint adhesivesealing may be required to ensure airtightness.

Like untreated wood, wooden fibreboardsmust be protected against UV-radiationand humidity. With a wood moisture con-tent of less than 20 per cent, theseboards are highly resistant to wood pestsand other sources of damage (bacteria,fungi, and insects).Wood fibreboards are available as insu-lating plaster-base elements for exteriorwalls. They are also suitable as elementsfor composite or sandwich construction incombination with hardboard or gypsumboard.

ManufactureIn the wet manufacturing process, waste(rom locally harvested coniferous trees ischipped and shredded. The chips arepulped with vapour in a reaction chamberand subsequently milled into fibres. Addi-tives and, if required, wood preservativesare blended into the fibre slurry. Theslurry is spread on a Foudrinier to createa flat fibrous mat, which is then dehy-drated by extrusion or by applying nega-tive pressure. In the final stage, the matsare shaped into boards and dried.Thicker panels (25-30 mm and upwards)are manufactured by laminating severalindividual boards.

MaterialCork, the outer bark of the cork oak tree,is available - as natural or expandedgranulated material (expanded cork, cak-ing cork) - in the form of insulating panelsand fill.The cork oaks, predominantly indigenousto the western Mediterranean region, canbe debarked every 8 to 10 years. Theyhave a lifespanof 100 to 150 years.

Applications)Cork is mould and rot resistant even whenthoroughly moist. However, exposure tomoisture over an extended period mayresult in fungal decay.Cork insulating boards are laid downloosely, then nailed, plugged or glued.Granulates are poured or injected. Insu-lating cork is especially suitable for usein areas subjected to pressure loadsand as impact sound insulation. Cork canalso be employed in composite insulatingsystems.

ManufactureCork is processed into insulating materi-als in a variety of ways depending on theintended use.

Natural granulated cork is manufacturedby crushing raw cork; it is used withoutadditives as insulating fill.

Expanded granulated cork is manufac-tured by adding superheated vapour tothe natural granulated cork under pres-sure in a hermetically sealed container.The natural cork resin (suberin) shifts tothe outside of the granules and bondsthem to each other. The required vapourtemperature depends on the resin con-tent. The blocks are then cut into slabs orgranulated.

Impregnated cork is manufactured byadding a bonding agent such as syn-thetic resin or bitumen to the heatedgranulate.

MaterialPlastic foams are oil-refining productsthat are manufactured by foaming the rawmaterial and simultaneously adding pro-pellants or blowing agents. Plastic foamsare porous in structure and are mainlyavailable as HR-foams.

Expandable polystyrene, also called sty-ropor, is a predominantly closed-cell,hard plastic foam. The "styropor" granu-late is processed into boards, mouldingsand sheets. The material is rot, mould andpest resistant. It is not resistant, however,to constant moisture or humidity.

Appiication(s)It is typically used in non-ventilated flatroofs (which must be protected againsthot bitumen), and composite insulationsystems for exterior walls.Rigid plastic foamboard is not very suita-ble for use in timber frameworks, how-ever, because it does not compensate forwood shrinkage.EPS boards are frequently employed insandwich constructions in combinationwith a variety of materials, for example,with fibrated cement panels as fagadeelements, or with timbering and plaster-board as wall and roof elements.In floor construction, EPS boards areused as impact sound and thermal insula-tion.

MaterialFlax is a textile fibre (belonging to thegroup of bast fibres) harvested from theroughly 1-metre-long flax plant. As insula-tion, flax is resistant to mould and canabsorb and release up to 20 per cent ofits own weight in moisture.

Application(s)Insulating mats of flax are used for roof,wall and floor insulation.Insulating feltings are used as impactsound insulation. Cavity flocks (insulatingmats cut into small pieces) and shives(wooden parts of the stalks) are used tofill cavities, (or example, sound-boardedceilings.Flax, in the form of pipe casing, is alsoused to insulate ducts and pipes.

MaterialHemp fibres are tear-resistant and alsohighly stress-resistant, which makes themsuitable as impact sound insulation. Sincehemp fibres do not contain protein, theyare naturally protected against pests andmould, thus obviating the need for addi-tives. Hemp fibres can absorb up to 18per cent of their own weight in moistureand release the moisture when the air isdry. They therefore have a balancingeffect on the interior climate.Hemp insulating materials are recyclable.

Applications)Hemp mats are used as thermal insula-tion in walls, ceilings and floors, as sub-or common-rafter insulation and asimpact sound insulation (d = 15/20/30 mm) below floor screeds.

ManufactureThe clay is prepared, finely ground,granulated and fired in revolving kilns ina countercurrent process at roughly1,200 "C The organic matter enclosed inthe clay is burnt off. Supported by heavyoil, the clay granules expand while thesurface melts to some degree and formsa sintered outer skin.

Vapour Retarding Layer/Vapour Barrier

DIN 4108-4

Vapour retarding layers or vapour barriersare essential layers in multi-shell ormultilayer wall structures, whose impor-tance with regard to building physicsand construction engineering is increas-ing as ever greater requirements areplaced on thermal insulation and energysavings.

MaterialVapour retarding layers are composedof coated or uncoated special papersand foils. They ensure that the outwarddiffusion of water vapour forming in abuilding can be metred and controlledthrough its thermal insulation. Permeatedor condensed water vapour has to bedissipated either directly or by ventilation.A seasonal balance at least must bemaintained to ensure that the thermalinsulation remains serviceable,

Vapour barriers are vapour-tight sheetsof plastic, metal foil or layered paperand/or synthetic materials, which preventthe outward diffusion of water vapourfrom the inside. Their vapour diffusionresistance is determined by the vapourdiffusion resistance of the individuallayers from the inside out. As a basicprinciple, each building element layershould permit more diffusion than thelayer below it.

The effectiveness of a vapour barrier isfundamentally dependent on the techni-cal and permanent connections that aremade. Perforations and permeation cansignificantly reduce the functioning ofvapour barriers.

PropertiesThe su-value, the water vapour diffusion-equivalent air-layer thickness, specifiesby how much lower the flow of watervapour is through a building elementlayer in comparison to an air layer ofequal thickness. The value is specified inmetres and is the product of the thicknessof the building material (s) and its watervapour diffusion resistance coefficient u.sD=uxs(m)

Metal foils with a thickness greater than0.05 mm are classified as absolutelyvapour-tight under DIN 4108-4. A materiallayer with a diffusion resistance of so=1500 m is considered vapour-tight forconstruction purposes. These materialscan be used as vapour barriers.

A material with a diffusion resistance2 < s0 < 1500 m can be used as a vapourretarding layer.

Materials with an sD-value < 0.3 m areconsidered diffusion-open.

Diffusion-openVapour retarding layerVapour barrier

sD< 0.3 msD 2-1,500 msD ;> 1,500 m

Recommendations for sealing joints, over-laps, junctions and penetrations of vapourretarding layers and vapour barriers arecontained in DIN 4108-7.

Building papers and sheeting, in additionto their function as a vapour retardinglayer or a vapour barrier, can also per-form the following functions in the struc-ture of a wall or roof construction:• Air-tight layer• Windproof layer• Waterproof underlay• Moisture barrier• Separating layerPay attention to the vapour diffusionresistance!

UseAir-tightness is a basic principle for awood construction designed to function inline with the requirements of buildingphysics and construction engineering.The high insulation values, which arerelatively easy to achieve, of the exteriorsurfaces will only be effective if theyare not cancelled out by leakagesinvolving condensation problems anddraughts.

What is required is a continuous, airtightlevel with a minimal number of junctionsand penetrations as well as joints andjunctions which are not only technically

simple and safe to install, but also takeinto consideration inevitable deforma-tions. Their correct installation can bechecked using a blower door test.

This requirement applies to vapour-permeable or ventilated exterior wallconstructions and especially to thosewhere the airtight level is also the vapourbarrier. The sealing materials must beco-ordinated and selected in accordancewith wood construction requirements. Asa rule, the air seal is attached inside andmay be identical to the vapour retardinglayer or vapour barrier,

The wind seal, however, is fastened onthe outside of the thermal insulation. Itprotects the thermal insulation fromexcessive cooling and prevents exteriorair from infiltrating, for instance, throughthe joints between the wooden construc-tion and the thermal insulation. To satisfythe requirement of increasing vapourpermeability from the inside to the out-side, a diffusion-open wind seal shouldbe chosen.

Damp-Proofing

DIN 18195-1 to 10

Building seals that meet the requirementsof DIN 18195 are designed to preventdamage caused by pressing or non-pressing water as well as by groundmoisture on the outside along the border-ing building elements.

Damp-proofing is also required to avertdamage to wooden elements that couldemanate from adjacent building elementssuch as concrete or masonry (buildingdamp) or be caused by damp from thesubsoil or weather.

For these seals, which are not included inDIN 18195, other types of bituminoussheeting can be used than listed barebitumen sheeting, asphalt roofing felt,asphalt roofing seal sheeting, bitumenseal sheeting, asphalt sheeting with dif-ferent interply sheets: e.g. thick PE foil orother flexible plastic sheeting.

DimensionsBitumen sheetingThickness (mm]: 4-5Width [cm]: 100Length [m]: 5

Plastic sheetingThickness [mm]: 1-3Width [cm]: 100,120, 130, 170,200Length [m]: 10,20,25

Separating layers become necessarywhen different building materials areconnected in such a way that their effec-tiveness is impaired or completely lost.

Typical examples of this are separatinglayers on anticapillary courses under-neath reinforced concrete floor slabs,separating layers between impact-soundinsulation and wet lines, or between sheetcovering and timber formwork, etc.

The following materials can be consid-ered for use as separating layersbetween different building elements:• Polyethylene foil• Polyester felts• Foam mats• Oil paper• Sodium bicarbonate kraft paper

Wood and wood-based materials are atrisk from vegetable pesls (fungi) and ani-mal pests (insects). When infestationoccurs, the outward appearance, the effi-ciency and the load-bearing capacity ofwooden structures can be reduced tosuch an extent that they are completelydestroyed.

Fungi require organic material (cellulose)for their development. They thrive particu-larly well in moist, warm areas without anair-flow. There are different types ofmould, e.g. "real dry rot". As a rule the rotcaused by fungi requires a wood mois-ture content of at least 20 %.

Insects, primarily beetles, e.g. wood ticks,use the sap area of the wood (predomi-nantly softwood), as a source of food andto house their larvae. The fully developedticks leave the wood through characteris-tic entrances. Not only living trees can beattacked, but also dry built-in timber, Awood moisture content of at least 10% isa precondition for infestation.

Wood preservation is subdivided intoremedial wood preservation, which isnecessary when infestation has alreadytaken place, and preventative wood pres-ervation, which stops infestation bydestroying the preconditions under whichthe pests thnv9.

Preventative wood preservationPreventative wood preservation can beachieved in several ways:- wood selection• wood preservation by design• chemical wood preservation

Wood Selection:It is important to select well-dried andseasoned timber (wood moisture contentu < 20 %) and, where possible, to use atimber species with great durability orhigh resistance (see appendix).

Structural wood preservation:This must be taken into consideration dur-ing the design phase e.g. when choosingthe location of the building, designing thefacade or planning protective roof projec-tions. When working out the details, how-ever, what must be avoided, above all, iscontact to the ground, the formation ofcondensation, and continual moisturepenetration of the wood by rain andsplashing water. Damp timbers must beable to dry out. Thus a fundamentalaspect of structural wood preservationinvolves aerating and ventilating the con-struction and the building element layersin order to allow any moisture to escape.

Chemical wood preservation:Fungus and insect infestation should beprevented by using chemical wood pre-servatives.

DIN 68800-3 differentiates betweenchemical wood preservatives for:• load-bearing and reinforcing wooden

building elements• non-bearing timbers which are dimen-

sionally unstable• dimensionally stable non-bearing tim-

bers for windows and exterior doors

Preventative wood preservation is com-pulsory for load-bearing building ele-ments. However chemical wood preser-vatives are only required for certain haz-ard classes, which are listed in DIN68800-3 (see appendix).

The standard merely makes recommen-dations for non-bearing building elementswhich are dimensionally unstable. Ifwritten agreement has been reachedbetween the architect and the builder, thewood need not be chemically preserved.Large-area application of wood preserva-tives should generally be avoided on theinterior.

Chemical wood preservatives need notbe used on windows and exterior doors ifheartwood complying with certain durabil-ity grades is used (see appendix).

Durability grades in accordance withDIN 1052:

Grade1

Descriptionvery durabledurablereasonably durablenot very durablenon-durable

Hazard classes:Under DIN 68800-3. timber building ele-ments and wood-based materials areallocated a hazard class ranging from GK0 to GK 4 - not at risk to highly at risk -according to their area of application.Hazard class 0 does not require chemicalwood preservation.

The application of chemical agents is notmandatory for classes GK 1 to GK 4either, e.g. if timbers are used which areconsidered sufficiently "naturally durable"for the hazard class in question.

A special certificate can also be obtainedto assign a structure to a lower hazardclass. To obtain this certificate, specialstructural measures must be taken todestroy destructive fungi and preventinsects from accessing covered timbers.

A wood moisture content of below 20 percent is required to avoid fungal decay.Insect attacks can be prevented by tak-ing structural protection measures, e.g.by using suitable cladding or by keepingthe wood moisture content below 10 percent. If the wood remains open and canbe inspected for insect attacks, chemical

od preservatives can also be avoided,'e.g. in undeveloped roof trusses, ifaccessibility is ensured.

Nearly all load-bearing and reinforcingbuilding elements can be classified asGK 0, with the exception of sills (GK 2).Chemical wood preservatives can also be[dispensed with here if sap-free pine,'larch or Douglas fir is used.

Chemical wood preservatives:Wood preservation by design should begiven priority in every case when buildingwood constructions. If it is pursued con-sistently chemical wood preservatives canbe avoided completely. Even under DIN,preventative chemical wood preservationis only a supplementary measure, andshould be taken only when wood selectionand design measures prove inadequate.

DIN 68800-3 specifies how the woodpreservatives are to be applied:• according to the inspection grades:

- insect repelling Iv- inimical to mould P- weatherproof W- inimical to mildew E,each preservative can be applied indi-vidually or in combination depending onthe hazard class.

• according to the wood species (roundtimber, sawn timber, laminated wood ...)

• according to the method of application(painting, spraying, dipping, boreholeimpregnation, vacuum and boiler pres-sure impregnation ...), including pos-sible pre-treatments of wood speciesthat are difficult to impregnate and theappropriate amounts to be applied forthe hazard classes stipulated, whilstobserving occupational health andsafety measures.

Pay attention to the manufacturers'instructions.Wood preservatives can be divided into:• water soluble wood preservatives,• solvent based wood preservatives,• oleaginous wood preservatives.

Water soluble wood preservatives:These preservatives contain inorganic ororganic salts as agents which act asbiocides.A problem with inorganic water-solublewood preservative salts is leaching causedby moisture, e.g. rain. Salts for hazardclasses 1 and 2 are always leachable andneed to be covered on site to protect themagainst moisture. Non-leachable salts forhazard classes 3 and 4 contain chromates(chrome-VI-compounds) and require a fix-ing period of several weeks in the wood.They need to be stored and protected fromrain during this time.

Organic water-soluble salts are approvedfor hazard classes 3 and 4 and fix inwood without the addition of chromates.

Solvent based wood preservatives:These comprise organic solvents andorganic compounds which act as bio-cides. There is a controversial publicdebate about some of the fungicides andinsecticides used (e.g. pyrethroid). Spe-cific problems arise when pentachloro-phenol (PCP) and lindane-containingagents are used indoors. For this reasonPCP has been banned in Germany since1990.

Oleaginous wood preservatives:These are creosote compounds andcreosoles.

Processing:For reasons of occupational health andsafety during processing, and to protectsubsequent occupants from exposure tothe agents and solvents contained in thewood, it is principally recommended thatclosed equipment be used to introduce thepreservatives into the wood (boiler pres-sure impregnation, possibly also troughimpregnation, spray tunnel procedure).

The processing of wood preservatives onthe construction site should be limited tothe treatment of sawn edges, etc. Further-more, the wood preservative should beapplied by brush and not sprayed.

Identification:Only products whose effectiveness andharmlessness have been demonstrated intests may be used as chemical wood pre-servatives. They are subject to theapproval mark regulation of the GermanLander and are issued with the Institute ofStructural Engineering in Berlin approvalmark when their usability has beenproven,

The area of constructed wood that hasbeen treated must be provided with long-term visible identification by the contrac-tor in accordance with DIN 68800-3.

Waste disposal:Remains of wood preservatives as well asempty containers and contaminatedpackages are hazardous waste. Timbertreated with wood preservatives must beincinerated as hazardous waste. Landfill-ing is prohibited.

Joint Sealing Tapes

Joint sealing tapes

DIN 18542

For invitations to tender and orders:• Manufacturer• Thickness• Width• Length• ColourCalculated per metre

MaterialOpen-pored and closed-cell materials areused for joint sealing tapes.Common types of sealing tapes are:• foam sealing tape• silicon sealing tape• butyl rubber tape

Open-pored sealing tapes are made ofpolyuretriane soft foam, for example,which is impregnated with pre-set flame-retardant synthetic resin, partially impreg-nated with bitumen, and can be pre-com-pressed at the factory for the applicationin question.

Closed-cell materials made of plastic areusually used for damp-proofing.

Open-pored materials have good soundinsulation properties, but are only effec-tive as damp- and wind-proof seals whencompressed.

Joint sealing tapes are available as singleor double-sided adhesive tapes.

UseJoint sealing tapes are used to function-ally connect building elements and build-ing element layers to each other. Accord-ing to the level of compression, they areeither driving rain or wind-proof, and cantherefore create both rain and wind barri-ers along joints.To prevent the formation of condensationat a joint's edges, the joint must have avapour-tight structure on the inside.

Processing:Sealing tapes are normally supplied pre-compressed (to approx. 20 per cent ofthe original thickness), whereby theretraction to the width of the joint is sogradual that it allows sufficient time dur-ing application to position the tape intothe joint.The seal effect of the joint sealing tapedepends on its residual compressionwhen in position:

cal members. The walls are in a two-skinform of construction and are braced bythe internal plywood lining. The inner leaf,in which the mechanical services arehoused, bears the loads from the floor,which stops short of the vapour barrier.This ensured a simple assembly of thehouse and a safe, airtight construction. Thewall is insulated with a total thickness of22 cm cellulose fibre. The problem of noisetransmission via the continuous verticalstuds was reduced by building the innerleaf of the wall with horizontal members.The floor is in a simple, hand-nailed verti-cally stacked plank construction. The

advantage of this system is that it allowsthe use of cheaper off cut products. Thefloor also has great rigidity, with a struc-tural depth comparable to that of a rein-forced concrete slab. No chemical pre-servatives were used for the wall, floor orroof timbers. ty DETAIL 1/1998
