|Product Code||Duty||Thickness||Width||Length||Area per roll|
|VTW-45||Light Wall||0.46 mm||1500 mm||30 m||45 m²|
|VTW-91||Light Wall||0.46 mm||3050 mm||30 m||91.5 m²|
* NOTE: For ABCB Climate Zone 1 and north of The Tropic of Capricorn in Climate Zone 2, substitute VapourTech® Wall with a Class 1 or Class 2 Vapour Barrier such as SilverSark HVB or SilverSark xR. VapourTech® Wall can be used as wall wrap in brick veneer systems. Where reflective cavities are desired, SilverWrap® xRS Micro-perforated is the preferred membrane for brick veneer systems outside of the humid tropics. If installed behind non-absorbent claddings such as steel, provision should be given for adequate drainage of any trapped moisture.
