THE MANY BENEFITS OF A SMARTFRAME SUB-FLOOR

SUSTAINABILITY

Anybody would think that sand, limestone, silica, iron oxide and alumina and steel mesh for concrete slabs “grew on trees” by the claims their proponents make regarding their “green” credentials. Trees are the ONLY renewable building material, and as they grow, they actually REDUCE the atmospheric greenhouse gas, Carbon dioxide. The same cannot be said for any of the other materials in a concrete slab.

SMARTFRAME

SUB-FLOORS REDUCE LANDSCAPING AND DRAINAGE COSTS

SmartFrame sub-floors reduces the need for expensive and potentially damaging earthworks and drainage on building sites. By adopting the SmartFrame sub-floor construction, the preservation of waterways, natural water runoff, rock outcrops and other natural features can be assured. Further, underground water flows and evaporation of ground water is not disturbed. Unlike many other floors systems, SmartFrame sub-floors are the environmentally friendly alternative.

SMARTFRAME

SUB-FLOORS ARE SERVICE FRIENDLY

Under floor ducted heating is the quick method of heating your home, which reacts quickly to changing weather conditions. It is easy to run the heating system components under the floor, and even site the heater unit out of site and away from harms way. Plumbing, water supply and electrical services can easily be accommodated under the floor, and unlike slabs, can be added to or altered during the life of the building. It is ONLY with a raised sub-floor that items such as water saving under floor rain and grey-water tanks or bladders can be fitted to either new or existing homes, allowing maximum usage of precious back yard space.

TIMBER FLOORS LOOK AND FEEL WONDERFUL.

The look and feel of the Till-Cote overlay solid floor system adds warmth and beauty to the whole house. Timber enhances the quality of your lifestyle. A polished timber floor is not only practical and easy to clean, but becomes part of your décor.

SMARTFRAME

SUB-FLOORS ARE COMFORTABLE

SmartFrame sub-floors are easy on the legs because they act as a shock absorber, i.e. they have some “give’’. A person on their feet all day often experiences tiredness and sore limbs if they have been on hard surfaces all day.

Further, underground water flows and evaporation of ground water is not disturbed. Unlike many other floors systems, SmartFrame sub-floors are the environmentally friendly alternative.

SMARTFRAME

SUB-FLOORS ARE HIGH AND DRY

SmartFrame sub-floors on stump or pier systems are OFF the ground and away from damp. This greatly reduces the risk of rising damp and flash flooding. Living off the ground allows a continual airflow under the house to assist in maintaining a comfortable dry floor. A poorly protected or faulty slab can absorb moisture. Problems that may occur include moisture damage to external and internal cladding materials, carpets and other coverings.

SMARTFRAME

SUB-FLOORS ARE PRACTICAL

SmartFrame sub-floors are easily adaptable to split level designs, with alterations and extensions able to be carried out with minimal disruption to the block. On sloping land a SmartFrame sub- floor can enable owners to create valuable under floor storage. Ideal for storing garden tools and even that wine collection.

SMARTFRAME

SUB-FLOORS and TERMITE CONTROL

Termites love damp soil and can nest beneath a concrete slab. It is impossible to lift the slab to check and carry out regular inspections. SmartFrame H2 sub-floors built off the ground allows for regular inspections to detect any evidence of termites before they get into the home.

SmartFrame Sub-floor Design Guide 3

The “feeling” that is identified when a person walks on a floor is very subjective. Some people want to feel a very stiff floor and others want some ”give” so that it softens the footing. When people say the floor “bounces”, it may be vibrating. This sensation is often caused by lack of dead load such as furniture, direct applied ceilings or other materials to absorb or dampen the vibration. The allowable spans shown in the tables of this manual have been designed to meet the strength and serviceability criteria in AS1684.1 - 1999. FACTORS THAT CAN AFFECT FLOOR DYNAMIC PERFORMANCE. • The choice of flooring system • The depth, stiffness and mass of the joists • Spacing of joists • Fixing of sheathing to joists • Stiffness and mass of floor sheathing • Mass and Stiffness of ceiling materials • Method of installation • Location and type of internal partitions and

furniture FACTORS THAT CAN IMPROVE FLOOR

DYNAMIC PERFORMANCE. Glue-nailed floors will perform better than

floors secured by nails alone. Deflection of the sheathing material

between joists can be reduced by decreasing the joist spacing or using a thicker and/or stiffer sheathing.

Proper installation is essential for dependable performance. Adequate and level support for the joists is necessary, as is correct fastening of the joists and sheathing.

The installation of a ceiling to the bottom flange of the joists.

Between joist blocking can provide some improvement to floor dynamic performance. It is emphasised that for between joist blocking to be effective, it is important that the blocking is continuous, this being easily achieved by the addition of a continuous bottom strap such as hoop iron strapping which is also attached to the end walls.

If floor dynamic performance is a concern to either the client, designer or contractor, then the above variables can be altered to improve dynamic performance. Some stiff floors with very little dead load may tend to vibrate. This can generally be dampened by directly attaching the ceiling below the underside of the joists.

5 STAR ENERGY RATING AND SMARTFRAME SUB-FLOORS

The introduction of the 5 Star Energy Rating Standard on 1 July 2004 in Victoria means that all new homes in Victoria will now be more energy and water efficient, this measure designed to reduce greenhouse gas emissions and reducing our demand upon precious water resources. 5 star homes should also save home owners money on their heating, cooling and water bills. The process of achieving a 5 Star rating is quite flexible, and while there is no single formula for obtaining a specific energy rating, a range of features can be used. These include:

i. Building orientation ii. Wall/ceiling insulation iii. Window type iv. Size v. Positioning vi. Shading and thermal performance vii. Floor products/insulation

There has been a popular misconception that homes with raised timber floors cannot achieve the 5 Star standard. This is incorrect, houses with timber floors can meet the standard. This means that you can continue using this traditional, easy, and often more cost effective mode of construction while enjoying the benefits that SmartFrame sub-floors offer.

The approach to successfully designing an energy efficient lightweight house with timber flooring will be different to the approach that works best for a design with high thermal mass, such as double brick on a slab floor.

Good building practice suggests that draughts should be minimised wherever possible. Typically, R3.2 ceiling and R2 wall insulation levels may be needed.

Good window design is important for all 5 Star houses, particularly those with timber sub-floors.

• To minimise heat uptake in summer, east or west facing windows may need to be shaded from the summer sun with eaves or blinds.

• For winter, a number of energy efficient options are available:

i. Thermally improved windows for some or all

windows. This included the choice of window frames used and/or the type of glass. For example, double-glazing can drastically reduce heat loss. Using double-glazing also overcomes the need to reduce window sizes particularly on south facing windows.

ii. Maximise north facing glass to increase winter heat build up, provided it is shaded in summer with awnings or blinds.

Tailoring the design to the site and orienting the house to make use of the winter sun are also particularly useful in achieving an energy efficient 5 Star outcome.

In May 2005, the minister for planning provided an extension until 30th April 2006 (Building Practice Note 2005-55) to the current 5 Star transitionary period for homes utilising suspended timber sub-floors.

This extension means that with timber sub-floors, you can simply use one of the following options:

4 Stars for the building fabric plus a rainwater tank, or 4 Stars for the building fabric plus a solar

hot water service, or 5 Stars for the building fabric

This document is not intended to be an exhaustive reference on the 5 Star standard, but is intended to give advice on what Total R-values (RT) a SmartFrame sub-floor system correctly fitted with certified insulation systems will provide.

CONCERTINA FOIL BATTSTM - SUB-FLOOR

QUICK AND EASY TO INSTALL EASY TO RETROFIT

“BREATHING” AIRSPACES ALLOWS GLUEING OF SHEETING

Perforated CONCERTINA FOIL BATTSTM allow moisture drainage and maximum breathing of timber flooring, and combined with still airspaces, produce high and c o n s i s t e n t t h e r m a l performance, reflecting 97% of radiant heat back to the floor. FOIL BATTS do not absorb or retain heat and therefore do not create warm cosy nesting environments for rodents or pests.

Total R-value of the structure (RT) is the sum of all component R-values, including the internal airspaces and the surface air films on either side of the structure. NB: Framing timbers are excluded from the Total R-value (RT), as per AS/NZS 4859.1:2002

• Staple FOIL BATTS to lower sides of floor joists (approx 5 staples) at a uniform maximum depth of 100mm to achieve the maximum Total R-value RT

for winter. FOIL BATTS are expanded creating a shallow concertina profile - with narrow joist centres gather up excess folds. For SmartFrame I-Joists, FOIL BATTS are stapled at 100mm depth. FOIL BATTS are lightweight, self supporting and sagging will not occur.

• Overlap adjoining FOIL BATTS by a minimum 50mm. No cutting is needed. Sealed overlaps are not necessary as heat flow is downward radiation in winter, i.e. there is no convective winter heat loss from floors.

• FOIL BATTS should be installed as flooring is laid and not be exposed unnecessarily to wind and rain. Open joist ends can be covered if necessary for protection from wind during construction. Install FOIL BATTS preferably after electrical, plumbing and ductwork are completed.

• Ensure the upper foil surface is clean, bright and free of all sawdust and debris to obtain best thermal performance, i.e. level the tops of joists first before fitting FOIL BATTS, then fit the flooring.

• FOIL BATTS perforations are specifically designed for platform sheet flooring, where roof is not on. Holes are in concertina valleys to allow quick draining of any rain penetrating the floor during construction, as well as any moisture formed by possible condensation.

• Timbers can breathe because of FOIL BATTS deep airspaces and unsealed overlaps. Beware of alternate insulations that require substantial perforations for drainage and breathing.

• The stated Total R-values RT are dependent on the creation of still air and zero air velocity beneath timber floors for both the airspace above and below

FOIL BATTS, and the upward foil surface shielded from dust accumulation on which maximises thermal performance.

• Enclosed building perimeters achieve this still air with:

i. Brick veneer or cavity brick construction - automatically creates still air. Ventilator plates are too small to permit high air speed and there is no need to block off or shield open joist ends.

ii. Weatherboard or fibro-cement cladding - minimise gaps between base boards and fix black close-weave shade cloth behind boards as a wind break. Open joist ends are wind shielded by the cladding itself.

• Open building perimeters (eg pole frame houses) require a perforated floor joist underlining to create still air and ensure breathing and drainage (eg roll foil)/cement sheeting). Open joist ends are wind shielded by the cladding itself. With 100mm joists, create two 50mm FOIL BATT airspaces which are surrounded by still air.

• Perforated FOIL BATTS can be installed under existing floors where there is adequate ground clearance . If there is a risk of condensation, then ensure that perforation holes are closest to the ground by reversing the folds of the stapling flanges.

• Under floor insulation does not require a 100% complete coverage, eg FOIL BATTS do not need to make a tight or close fit around ductwork.

CONCERTINA FOIL BATTS do not form a stable base to harbour vermin under timber floors.

* The timber species in SmartFrame LVL13 are not susceptible to Lyctid Borer attack. A more comprehensive Hazard Class Table is available in AS/NZS1604.4:2004, but it is NOT recommended that SmartFrame LVL13 be used in end uses with exposures requiring treatment in excess of H3. Experience is showing that LOSP treated timber in the outside above ground (H3 Hazard Class) may experience some leaching of the active ingredients of the LOSP treatment. To minimize the possibility of timber degradation in these situations, it is recommended that: Smart Guard H3 treated LVL13 NOT be used where the surface is horizontally exposed AND unprotected from water entrapment OR where post-treatment protection cannot be maintained. Post treatment protection may include:

(i) ProtectadeckTM high density water proof joist/bearer cover or malthoid capping (j) An impervious membrane such as regularly maintained painting or staining. (ii) Construction detailing to prevent water entrapment.

SmartGuard H3 treated timber can be painted just like dry untreated timber, however the primer must be an oil based primer, even for waterborne (acrylic) top coats. FASTENERS FOR SmartGuard H3 LVL

For SmartGuard H3 LVL to be used in exposed exterior applications, it is recommended that either hot dipped galvanised of stainless steel fasteners are used.

SMARTGUARD™ TREATMENT SmartFrame LVL13 can be supplied SmartGuard™ LOSP treated to H3 hazard class levels, as per AS/NZS 1604.4:2004. (Note: Water borne treatment processes are NOT suitable for SmartFrame LVL13). The hazard class number selected is based upon the specific exposure condition for the proposed end use of the SmartFrame LVL13, as shown in the table below.

In-line bearer and joists can assist where ground clear-ance is at a minimum or allows average overall depth of the floor to be minimised but maintaining the long span capability of the joists

Stacked bearer and joist allows continuous span joists to be used (supported at 3 or more supports). Continuous spans may reduce the joist depth in some circumstances.

• Depths from 200 to 450 mm (Only 200 and 240 reproduced below) • Lengths up to 12.0 metres in 300 mm increments • 25 year treatment warranty on H2 treated product (conditions apply)

RECOMMENDED MAXIMUM SPANS FOR RESIDENTIAL FLOORS GENERAL DOMESTIC - 1.5 kPa

In compiling the span tables in this manual, the requirements of the relevant Australian Standards and codes along with established Industry standard design guidelines for Residential Construction have been followed. In par-ticular, the following codes and references have been used:

AS/NZS 4063:1992 Timber - Stress graded - In-grade strength and stiffness evaluation. AS 1170.1:1989 SAA Loading Code Part 1: Dead and live loads and load combinations. AS 1720.1:1988 SAA Timber Structures code Part 1 - Design Methods AS 1684.1:1999 Residential timber-framed construction

SERVICEABILITY CRITERIA Max permanent load deflection - lesser of span / 300 or 15 mm (j2 = 2) Max live load deflection - lesser of span / 360 or 9 mm FLOOR DYNAMIC PERFORMANCE CRITERIA Minimum Natural Frequency - 8 Hertz Maximum differential deflection between Joists of 2 mm under a concentrated load of 1.0 kN mid-span. FLOORING: Spans are suitable for solid timber, particle board and ply flooring. Floor sheathing glued and nailed to the joists will improve floor rigidity. Where a heavy overlay material is to be applied, such as thick mortar bed tiled or slate floors, the permanent load allowance should be increased to 1.2 kPa. A reduction of joist spacing can be used to accommodate this extra permanent load. A satisfactory result can be achieved by adopting the maximum spans for 600-mm and 450-mm spacings but installing the joists at 450-mm and 300-mm spacings respectively.

Q. Are the glues used in SmartFrame Engineered Wood Products safe? A. Yes, they are safe, Phenolic resins used in our Engineered Wood Products are stable, polymerised materials. The polymerisation reaction is non-reversible (i.e. once the polymer is formed, it doesn’t break down). A wood dust warning label is provided for all SmartFrame wood products to alert our customers that wood dust can be generated by sawing, sanding, or machining wood and wood products. Q. What is the level of formaldehyde emission from our phenolic-bonded Engineered Wood Products? A. Tests have confirmed that formaldehyde emissions from our phenolic-bonded products (ie. OSB, LVL, I-Joists, and Glulam) are well below 0.1 ppm under reasonably foreseeable conditions of use. Independent third party testing in accordance with ASTM E 1333, “Determining Formaldehyde Levels From Wood Products Under Defined Test Conditions Using a Large Chamber”, has shown formaldehyde emissions from the products to be below 0.1 ppm. In short, all available information indicates that formaldehyde levels associated with phenolic resin-bonded wood products are similar to those of the dimension lumber veneer or other forms of wood used to make the products. Q. How much formaldehyde is in our phenolic-bonded, Engineered Wood Products? A. The amount of formaldehyde in our Engineered Wood Products is less than 0.1 percent of the dry weight.

Q. What is being done to reduce the exposure to formaldehyde? A. Formaldehyde is normally present at low levels, usually less than 0.03 ppm, in both outdoor and indoor air. Efforts have been made by both government and industry to reduce exposure to formaldehyde. A 1985 regulation by the US Department of Housing and Urban Development (HUD), covering the use of manufactured pressed wood products in housing was designed to ensure that indoor levels were below 0.4 ppm. Product standards established for plywood and particleboard led to significant reductions in formaldehyde emissions from those products. Furthermore, HUD acknowledged that phenolic resin bonded wood products emitted such small quantities of formaldehyde that these products were exempted from all the testing and certification requirements of the standards. In Germany, the German Hazardous Materials regulation, better known as the “E1” Standard, sets a limit of 0.1 ppm for formaldehyde emissions from some wood-based composite products. All available data indicates that our phenolic bonded Engineered Wood Products meet this requirement. Q. What affects formaldehyde levels in a home? A. Formaldehyde levels in the indoor air depend mainly on what is releasing the formaldehyde, the temperature, the humidity, and the air exchange rate (ie. the amount of outdoor air entering or leaving the indoor area) Levels of formaldehyde decrease with increasing air exchange rate, decreasing temperature, and decreasing humidity.
