SilverWrap® xRS

By delivering an optimised level of reflective insulation, SilverWrap® xRS will save on requirements for bulk insulation. Under standard calculation assumptions in accordance with AS/NZS 4859.1:2002/Amdt 1:2006, a non-reflective house wrap will require R2.5 insulation batts to satisfy minimum NCC requirements.

By choosing SilverWrap® xRS, R1.8 batts will be sufficient to achieve compliance with national energy efficiency provisions.

SilverWrap® xRS is designed for use where water barrier and Class 1 Vapour Barrier properties are required for use as a wall wrap in residential and commercial buildings in BCA climate zone 1 and regions north of the Tropic of Capricorn in Climate Zone 2.

Class 1 Vapour Barrier wall wraps are not recommended for regions south of the Tropic of Capricorn in Climate Zone 2.climate zones 3-8.
