VapourTech® Brane® VHP

VapourTech^® Brane^® VHP is used as a wall wrap behind all types of cladding and in all wall systems in Climate Zone 2-8

NOTE: It is NOT recommended for this application in ABCB Climate Zone 1; select from our range of Class 1 and 2 Vapour Barrier products instead.

VapourTech^® Brane^® VHP can be used as wall wrap in brick veneer systems; however, SilverSark^® xR Micro-perforated is the preferred membrane for brick veneer systems outside the humid tropics.

VapourTech^® Brane^® VHP is available in 1.37 m and 1.5 m width rolls, and a convenient 2.74 m width roll that halves installation time and reduces the amount of air gaps and joins in the wall system.

If installed behind non-absorbent claddings such as steel, provision should be given for adequate drainage of any trapped moisture.
