CONCERTINA FOIL BATTS TM - SUB-FLOOR QUICK AND EASY TO INSTALL EASY TO RETROFIT Total R-value of the structure (R T ) 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 (R T ), as per AS/NZS 4859.1:2002.

For R T values for alternative joist depths, contact Wren Industries Pty Ltd Perforated CONCERTINA FOIL BATTS TM allow moisture drainage and maximum breathing of timber flooring, and combined with still airspaces, produce high and consistent thermal 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. “BREATHING” AIRSPACES ALLOWS GLUEING OF SHEETING SmartFrame Sub-floor Design Guide 7
CONCERTINA FOIL BATTS TM INSTALLATION INSTRUCTIONS - FLOORS* 1) Staple FOIL BATTS 90mm down on sides of floor joists (approx. 6 staples) with a maximum airspace depth of 100mm to achieve the maximum R-value for winter. FOIL BATTS are expanded creating a shallow concertina profile and held taut with staple in flange corners, to minimise sagging. With narrow joist centres gather up excess folds. For 200mm “I” beams, FOIL BATTS are stapled at 100mm depth. FOIL BATTS are self supporting. 2) Overlap adjoining FOIL BATTS by a minimum 50 mm. No cutting is needed. Sealed overlaps are not necessary as heat flow is downward radiation in winter, ie. there is no convective winter heat loss from floors (refer 7 still air). 3) FOIL BATTS to be installed as flooring is laid and not be exposed to wind or rain. Open joist ends should be covered if necessary for protection from wind and rain during construction, eg dampcourse type material. Install FOIL BATTS preferably after electrical, plumbing and ductwork are completed. 4) Upward FOIL BATT 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. 5) Drainage. 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 (low risk generally). 6) Timbers can breathe because of FOIL BATTS deep airspaces and unsealed overlaps. Be aware that alternative insulations will require substantial perforations for drainage and breathing. 7) Still air. The stated Total R-values are dependent on the creation of still air and zero air velocity beneath timber floors for both the airspace above and below FOIL BATTS. 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 entry and exit. (ii) Weatherboard or fibro-cement cladding – minimise gaps between base boards and fix black close-weave shade cloth behind boards as a wind break. No air speed. Open building perimeters (eg pole frame houses) require a perforated floor joist underlining to create still air and ensure breathing and drainage (eg building paper/foil). With 100 mm joists, create two 50 mm FOIL BATT airspaces which are surrounded by still air. 8) Existing Floors. Perforated or non-perforated FOIL BATTS can be used. 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. 9) Coverage. In winter 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. 10) Electrical Safety: Ensure all health and safety precautions are taken when stapling Concertina FOIL BATTS in close proximity to electrical cabling. Aluminum foil has the ability to conduct electricity, and incorrect installation will provide a safety risk. If in doubt consult a qualified electrician. For further information contact Wren Industries. (i) New house construction: In new house construction and renovations it is typical that there is no preexisting electrical cabling fixed to sides of floor joists, and therefore it is safe to use metal staples for fixing fibre batt or foil insulations such as Concertina FOIL BATTS between joists. (ii) Retrofit insulation: Where electrical cabling exists and fitted to sides of floor joists, simply position Concertina FOIL BATTS above or below cabling to avoid potential conduction.

Tilling Timber accepts no responsibility for errors, omissions in the fixing details and any responsibility whatsoever in the use of FOIL BATTS in general.
