5 STAR ENERGY RATING AND SmartFrame SUB-FLOORS To enable designers of SmartFrame sub-floor systems to assign Total R-value R T the floor for input into energy rating programs or manual calculations, Tilling have complimented their SmartFrame floor systems with the certified CONCER- TINA FOIL BATTS TM insulation system developed and marketed by Wren Industries Pty Ltd. TECHNICAL SUPPORT Because of the importance that Tilling’s place on the provision of expert technical support for their SmartFrame range of Engineered Timber Products, designers of sub-floor systems are free to contact the SmartData customer helpline on 1300 668 690 or at smartdata@tilling.com.au to seek advice on how to use the Total R-values R T in this Design Guide with energy rating software. Designers are also recommended to visit www.wpv.org.au/5star and download the excellent PDF “Timber - more than a 5 star energy solution” For further information specifically related to the CONCERTINA FOIL BATTS, contact Wren Industries Pty Ltd on (03) 9532 5855, or email info@concertinafoilbatts.com.

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 6
