ISSUE 09/08

All Wickes PVCu and Softwood windows conform to Part L of the Building Regulations.Part L is the section of the Build Regulations for England and Wales that sets thestandards for energy efficiency in buildings. The equivalent section of the ScottishBuilding Regulations is know as Part J. This legislation is designed to ensure thathomes become more efficient in terms of the amount of energy they consume.

In the past the Building Regulations mainly applied to ‘new builds’. However theserecent changes also apply to refurbishment projects. This means, if you are planning tochange existing windows you will either need to have these installed and certified by amember of FENSA (Fenestration Self Assessment scheme) or you can have thewindows and installation checked and certified by your local Building Control Office.

If the windows are being fixed into critical locations as defined in Part N of the BuildingRegulations and shown in FIG.1, then toughened glass must be used. Only Wickes PVCuMade-to-Measure windows fitted with toughened glass can be fitted in these locations.Building Regulation Part B may also call for certain windows to be suitable for a means ofescape route in the event of fire. Our PVCu Made-to-Measure windows can be fitted withegress hinges to achieve this, provided the necessary size is specified.

To comply with Building Regulations, ensure all applicable sizes and designs of openingsashes allow for a suitable fire escape route. Typically the open window should have anunobstructed emergency exit space of 0.33m2, with a minimum height and width of 450mm.Side hung opening sashes are the most suitable, particularly in upstairs situations. Narrow tophung sashes or vent lights are not appropriate. For escape purposes the bottom of the frameopening area should not be positioned more than 1100mm from floor level.

Wickes offer an egress hinge for side hung opening PVCu windows that are available to TakeAway In-Store.

NOTE: You should always fit fire detectors /smoke alarms in the house to give earlywarning of potential danger. Remember totest them regularly – it is no good if theydon’t work.

All our PVCu windows are designed forinternal glazing, which prevents theremoval of the glass by intruders from the outside.

For exterior beaded windows a similar levelof security can be obtained by glazing withsecurity glazing tape.

The type of frame you choose i.e. softwoodor PVCu, will depend to a large extent on thestyle of your house and personal preference.

MADE TO MEASURE WINDOWSFIG. 4 shows the styles of Made-to-MeasureCasement windows available in PVCu. TheMade-to-Measure range has all the samebenefits as the Take Away range but allowsyou greater choice of styles, glass option andsize.

The maximum size of sealed units in openinglights or fixed panels is determined by Codesof Practice approved by the Glass and Glazing Federation. You do not have to calculate

glass sizes yourself. When ordered, the framesare made to conform so that the sealed unitsizes and the sizes of opening lights are withinthe limitations.

BEFORE YOU STARTCheck whether or not your old frames cansimply be replaced by one of our In-Store windows, or you need to order a Made-to-Measure window.

To calculate the frame size needed, you mustcarefully measure the existing brickworkopening size from the outside. Do notmeasure the existing window frame, whichwill be less than the brick opening. If the wallaround the existing window is rendered overthe frame, some of the rendering must bechopped back to bare brick so that accuratemeasurements can be taken. Measure in atleast three places on both the height andwidth. See FIG.5.

If there is any variation in height or width,note the shortest measurement in eachdirection. These are the measurements to beput on the order form in millimetres.

DO NOT deduct anything for clearancepurposes. The necessary allowance will bemade when the frame is built, since thisvaries depending upon the window type.

Frames that are Made-to-Measure fit intobrick openings measured by you, andtherefore must be measured correctly inorder to fit. Remember, it is your responsibilityfor getting those measurements right. Doublecheck your measurements for both heightand width, or get someone else to check foryou. Use the shortest height and widthmeasurements.

Once a frame has been made to suit the sizeyou have specified, mistakes cannot berectified and frames cannot be altered.

ADDITIONAL PRODUCTSREQUIRED

Fixings to secure the frames to thesurrounding brickwork are not supplied.

For timber frames you will require 8 x 80mmFrame Fixers (510-000) or 10 x 100mmFrame Fixers (510-002) depending upon thegaps between the frames and brickwork. Thescrews should penetrate at least 32mm intothe brickwork.

For the PVCu frames you will need ourspecial PVCu Window Frame Fixers (510-001 or 156-687).

All are in packs of 10 fixers.

Wickes Professional Woodstain in the colourof your choice will also be needed for timberframes, unless paint is preferred in whichcase you should use Wickes Master Exterior,Primer Undercoat and Exterior Gloss.

For timber frames you will also require aFlexistrip Glazing Tape (207-564), framesealant and Decorators Filler for makinggood.

For PVCu frames you will need WickesDecorators Filler, Wickes White Framesealand Wickes Expanding Foam Gap Filler forthe installation.

4. Timber frames

1. REMOVING THE OLD WINDOW

This should not be done until your new frameis on the premises and you have checked thesize and condition. You do not want anopening left for an intruder to gain access tothe house.

NOTE: To reduce damage to the decorativefinish, carefully score around the window,between the frame and the decorated wall(this will only help if the plaster is in goodcondition). Always assume that someredecoration may be necessary.

Start the frame removal by unscrewing andcompletely detaching any opening lights atthe hinges or by removal from the VSSframe.

Rake out the putty holding the glass in timberfixed lights and extract the small metalglazing sprigs, which will be found atintervals round the frame up against theglass. You will have to use an old chisel or asimilar tool to chop out the old hard putty.

Take care not to break the glass.

Remove the glass completely and putcarefully aside. It may prove useful at somelater date. With all the glass and openinglights removed you should be left with justthe old frame still attached to the brickwork,probably with nails, so it needs to be literallycut out of position. Start cutting through thetransoms or mullions as in FIG. 6, removingthem completely.

Follow this by cutting through the side jambsat an angle about one third of the way upfrom the sill. Take care not to damageinternal plastering with the saw blade.

If external rendering covers the outside edgeof the frame this rendering will have to bechopped back to the brickwork. This willfirstly enable the old frame to be cut out andlater to allow the new frame to be inserted.Insert a crowbar or similar tool behind the cutjambs and lever away from the wall.

NOTE. Place a flat piece of waste wood of asuitable size, between the brick / plaster andthe crowbar, this will reduce any damage tothe hard surface when pressure is applied.

Once you can get sufficient grip on the jambsuse your hands to completely pull out the oldtimber as seen in FIG.7. Where the jambsare mortised into the head and sill the tenonsshould break away easily.

Remove the head and sill in similar fashioncutting through them, then levering away.Take great care with the head particularly, asto not damage the internal plastering byusing this as a solid surface to lever against.It is likely that the old frame head will stillhave projecting ends (horns) embedded intothe brickwork at each side. Once the cuthead sections have been levered off thenails, these projecting ends should pull easilyout of the wall. The resulting holes should befilled with a mortar mix since they cannot beused again. Once all the timber has beenremoved, check the opening by removing oldnails and traces of old mortar used to in-fillthe gap between the frame and the brickworkto leave a clean clear opening.

If you discover or even suspect that the oldtimber shows signs of dry rot you shouldtreat the brickwork with Wickes All Purpose

Wood Treatment. Brushing this on will kill anyremaining spores embedded in the masonry.

2. PVCu VSS WINDOWS

PVCu VSS windows are only Made-to-Orderand are supplied pre-glazed.

Window features:A. Spiral sprung balance

Pivot bars are fitted to the bottom of thesash. This allows the sash to tilt inwards foreasier cleaning.

All balances are pre-tensioned at the factorybefore the window is despatched, howeversome small adjustments may be necessaryon site.

NOTE: Care must be taken not to overtension the balance. The balances should beregularly maintained as per manufacturer’sinstructions.

B. Travel stops

Travel stops are positioned to the top andbottom of the window, these are essential,and ensure that the spring balances do notbecome prematurely worn or damaged.

C. Tilt latches

Tilt latches provide a secure method ofretaining the sashes in the upright positionand also allow the sash to tilt when required.They work by engaging the jamb profile toprovide an easy sliding movement withoutthe risk of the sash inadvertently droppinginto the tilted position.

D. Sash locks

As well as providing a secure lock, the sashlock incorporates a sweeping cam to pushthe sash into a fully closed position ensuringa good seal at the head and sill of thewindow and at the meeting rail.

E. Removing the vertical sliding sash

• Release both tilt latches inwards and support the weight of the sash as you tilt the sash into the room.

• Release the bar restrictor (if fitted) by removing both screws from the sash slides and remove the bar from the sash. Then lower the sash to the horizontal position.

• Using a screwdriver prise the black plastic rivet from its location holding the pivot bar in place.

• Slide the sash off the pivot bars – this operation may require assistance to ensure that the sash is not damaged.

NOTE: It is important to take care and makesure that the balances are fully retracted andthat the sash is tilted in excess of 90º whenremoving as failure to do so could result inan injury.

Do not remove the travel stops.

F. Maintenance

To ensure your VSS windows provide thebest possible service it is important that thefollowing maintenance schedule is adopted:

• Clean the windows at regular intervals witha propriety brand cleaner.

• Check that the balance fixing screw is secure – but don’t over tighten the screw.

• Check that the bottom fixing bracket is secured to the sash and not damaged or distorted in any way.

• Check that the top pin roll in the spiral is engaged in the pivot shoe and the bottom roll.

• Check that the tube is not damagedin anyway.

• If dirt and debris has built up at the bottomend of the balance, this should be cleanedwith a cloth and re-greased.

Care should be taken not to contaminate thepivot shoe or the slide channel.

• Check the travel stops are in place and that the sashes move to contact the travel stop without undue force. This will ensure that the balances are not being either over extended or crushed. Check that the sashes run smoothly, if required adjust balances as per manufacturersinstructions.

3. PVCu FRAMES

Made-to-Measure, Take Away, and Made-To-Order.

Frames all come with the fixed glasstemporarily in place and without the sills, butsash frames / opening lights within thewindow are factory glazed so please DONOT try to remove the glass. The only workyou will need to do is fit the handle. (Minoradjustment of the hinges may be necessaryif the window is fitted out of plumb).

For the Take Away PVCu windows, Sills andhandles are sold separately.

Made-to-Measure and Made-to-Orderwindows are supplied with Sills and handles.included.

Before installation of the frame remove all the fixed glass. This is done by removing the vertical beads from the securing nibs by exerting pressure in the direction shown in FIG.8.Where the window is too big to handlecomfortably, we suggest that the sashpanel(s) are removed by unscrewing the topand bottom hinge from the outer frame andstored safely to be fitted after the windowframe is installed.

It may be necessary to use a wide bladedstripping knife to help lever the beads out ofposition but take care not to damage thePVCu frame edges. Put the sealed unitssafely aside resting on timber blocks andleaning against a wall. Do not stack them flatone on top of the other.

Fit the sill to the frame next. Drill 5mmdiameter clearance holes right through thesill section from the underside as in FIG.9 with holes at 200mm maximum fromeach end and at 600mm centres in between.

Rest the sill on the frame with the upstand tothe inside of the frame. Drill 3mm pilot holesthrough the centre of the sill clearance holesinto the mainframe. Remove the sill.

Run a bead of white silicone frame sealantalong the face of the sill upstand.

Replace the sill bedding well down onto thesilicone and secure with screws provided(No.8 x 13/4" pan pozi). Do not overtighten the screws, as this may distort the sill. If overtightened slacken off slightly to removeany distortions. FIG.10.

Wipe excess silicone from the joints. Usingmore silicone as a seal and adhesive, fit thesill end caps, pushing them firmly into place.Use a little masking tape to hold them inplace until the silicone has cured. Clean offexcess silicone.

Lift the frame into the prepared opening.Ideally there will be about 5mm clearance allround the frame. Use wedges (wooden orplastic) stretching from the inner edge of theframe to the outer edge to set the framecentral, level, square and plumb in theopening. Check for squareness by measuringthe frame diagonals, as seen in FIG.11. Theymust measure exactly the same. Use a spritlevel to check they are set vertical and levelFIG.12.

FIG.13 shows the positioning of wedgeswhich have to be removed later or coveredover. Once the frame is set drill clearanceholes through the frame and into thebrickwork for the PVCu frame fixers. Holeswill be required at 200mm from accessiblecorners, at the ends of prefixed hinges and atmaximum 600mm centres in between.Countersink the frame for the screw heads.

Tap in the fixers. Tighten the screws so thatthe frame is securely held but not so tight thatthe frame is distorted or so that excessivepressure pulls the welded frame joints apart.Apply a small amount of silicone to the screwshanks and heads to ensure that they aresealed against the PVCu frame.

Alternatively, for internal fixing use the plasticfixing lugs (provided). Twist / clip the lugs inplace on the edges of the window frame andsecure into the internal brick or breeze block.NOTE: when using an existing opening the

plaster should be chipped away, the fixinglugs inserted and the fixings re-plasteredover. With 'New Builds' the fixings should beplastered over to finish as normal practice.

GLAZING

We suggest that you start with the fitting ofthe smallest sealed unit, since this will beeasier to handle. FIG.14 shows the locationof setting and spacer blocks for the frames.

Opening sash lights do not require toeing and heeling as they are factory glazed. They may however require minor hingeadjustment to perfectly align the window.Position setting blocks in the bottom of theframe as in FIG.14.

Thoroughly clean the glass with a dry lint freecloth especially around the perimeter of theface which will be against the e-gasket. If thisis not clean and dry it will not adhereproperly. It is important to install the glass thecorrect way around to gain full benefits of theLow E coating. Check the glass label forcorrect orientation. Place the sealed unit intothe frame resting on the setting blocks. Try tokeep the glass just clear of the exposedglazing tape in the frame corners. Centralisethe unit in the frame, inserting spacer blocksas necessary to ensure the sealed unit isproperly aligned within the frame, and theframe is square.

After the positioning of the glass, fit the topglazing bead into the frame. Ensure that the

nibs engage correctly as in FIG.15.

Now fit the bottom glazing bead and then theside glazing beads in similar fashion. You willnote the side beads are formed to fit over thetop and bottom glazing beads.

It will be necessary to exert some pressureon the glazing beads to get them to engagecorrectly. Complete all glazing for the windowas above.

MAKING GOOD

The wedges used for the original setting ofthe frame must now be removed. The gapbetween the frame and brickwork must bepartially filled with Wickes Expanding GapFoam Filler. Do not attempt to fill in oneapplication. Since the foam cures by reactingto moisture in the atmosphere you shouldonly apply layers about 15mm thick at a time.Only when one coat of surface has curedshould you apply the next. It is helpful tomoisten the cavity with a water spray beforeusing the foam to improve adhesion andcuring but do not allow excess water to lie inhollows.

Do not overfill the cavity since this wouldcause the frame to bow inwards as the foamexpands and it does expand considerably.Fuller instructions for the use of the foam willbe found on the container. Once the foamhas fully cured the external face of it shouldbe covered by a coat of white silicone framesealant, and internally by Decorators Filler.

FIG.16 shows the filled cavity. Do not infill thegap around the frame with a rigid materialsuch as a mortar mix. The infill material mustbe flexible to allow the PVCu to expand andcontract naturally.

NOTE: A wise precaution is to use maskingtape to prevent the foam from coming intocontact with the front of the windows. Thistape should be peeled off immediately afterthe foam has been applied.

4. TIMBER FRAMES

Take Away Timber Frame(s) are not suppliedwith glass. Glass to the correct size can beeasily purchased from a local glassmerchant.

NOTE: Sizes can be found in FIG. 3.

Before starting, make sure you haveeverything you need to complete the job. Forsite glazed windows, the glass units must bestacked on edge on timber battens, leaningback at a slight angle against a firm support.Take particular care not to damage corners.Store the glass in a dry place where there isno risk of it being knocked.

With the brickwork opening prepared, theframe can be lifted directly into position fromthe outside. There should be a gap of about5mm from side to side and top to bottombetween the brick opening and the frame.These gaps will allow the frame to be alignedcorrectly and set squarely. Set the frame intothe opening so that the drip groove on theunderside of the sill is well clear of theoutside wall. Get the sill level first, usingdurable wedges to push the frame head upagainst the lintel above. Check that it is levelusing a long spirit level, adjusting the wedgesas necessary.

Now align the jambs - the vertical framesides. They must be perfectly vertical. Againuse a spirit level on both the outside facesand the glazing faces to check that they arevertical. Use wedges to hold the frame in thecorrect position. Check for squareness bymeasuring the frame diagonals, FIG. 11.They must measure exactly the same.

Adjust the thickness of the wedges ifnecessary to ensure accurate squarepositioning. As a final check un-latch theopening lights to make sure they do openfreely. Secure the frame to the brickwork usingthe frame fixers. Drill and countersinkclearance holes in the frame and through intothe brickwork 150mm from each corner and atmaximum 600mm intervals in between allaround. Alternatively fixing straps can be used.

Keep the clearance holes in the centre of theglazing rebate, where they will in due coursebe covered by the glass. Knock in the fixersand drive home the fixing screws taking carenot to distort the frame.

When painting, particular care must be takento ensure that paint does not get onto thewool pile seals or moving parts of thewindow.

Always take particular care when installingfactory finished timber windows to ensurethat the paint finish is not damaged prior to,or during installation.

GLAZING TIMBER FRAMES

For installing double glazed units into WickesTimber Casement Windows with drained andvented bottom beads.

The Glazing Strip system is now therecommended way of installing double glazedunits into Wickes Timber Windows. Withdrained and vented bottom beads, it is quick,clean and simple to use and will not hardenor crack. When correctly applied andmaintained, it provides a weatherproof sealand will protect double glazed units for up to4 times longer than traditional methods.

Step 1 Remove all dust, grease and loosematerial from the rebate. Any moisture on thetimber should be wiped off using a cleanpaper towel or other absorbent material togive a dry surface. Check that the unit fits intothe frame and can be correctly positioned tofacilitate drainage and ventilation. Whenstanding the unit on setting blocks checkthere is a minimum 5mm edge clearance atthe bottom of the unit. It is important to installthe glass the correct way around to gain fullbenefits of the Low E coating. Check theglass label for correct orientation. The spacerbar should ideally be level with the sightlineor slightly below.

Step 2 Starting at one corner, apply GlazingStrip to the face of the unit with the bottomedge of the backing paper aligned with theedge of the unit. Cut the end of the GlazingStrip and the backing paper flush with theend of the unit using a sharp blade. Fold backapproximately 5cm of the backing paper fromeach end to expose the strip sealant.

Step 3 Begin the application of the secondlength of Glazing Strip by forming a butt jointagainst one of the exposed sections ofGlazing Strip already applied. Do not overlapthe strip or leave gaps between adjacentsections of strip and do not makeindentations at the joint. Continue by aligningthe backing paper with the edge of the unitand cut the Glazing Strip and backing paperas before.

Step 4 Continue to apply Glazing Strip alongthe perimeter of the unit as described aboveuntil you reach the final joint. When the fourthlength reaches the exposed section of thefirst length, fold the strip back on itself andcut through the backing paper and strip at thecrease so as to form a neat joint. Replace thebacking paper onto the strip at the fourcorners. Carefully turn the unit over and applystrip to the face of the unit following the samemethod used for the first side.

Step 5 Position the setting block(s) on thebottom rail as near to the quarter points aspossible as shown. Where more than one unitper window is to be glazed, start by glazingthe bottom unit(s).

Step 6 Remove backing paper from one sideof the unit and position the bottom of the uniton the setting block(s). Centralise in theframe before the Glazing Strip makes contactwith the rebate upstand. Guide the unit backuntil the strip sealant touches the rebateupstand on all sides. Press firmly all the wayround the edge of the double glazed unit toensure that the Glazing Strip is compressedbetween the unit and rebate upstand.

Step 7 If glazing an opening sash, insertlocation blocks around the unit as shown inFIG. 14.

Step 8 Remove the backing paper from thestrip facing you. Take the bottom bead andplace onto the platform.
