One Fabric. Two Jobs.
A house wrap — also called a building wrap or weather-resistive barrier — is installed on the exterior wall framing beneath the cladding or facade. It manages two simultaneous and opposing moisture challenges in a wall assembly: preventing liquid water from wind-driven rain penetrating inward, while allowing moisture vapour generated inside the building to escape outward.
A wall that blocks all moisture traps the vapour buildings produce continuously and causes condensation, mould, and structural decay within the wall cavity. A wall that allows free moisture transmission admits wind-driven rain and destroys insulation and framing. The house wrap solves both simultaneously — a one-way moisture valve at the building scale.
➤ Woven PP House Wrap
Woven polypropylene house wraps offer higher tear resistance and puncture resistance than spunbond alternatives — critical on construction sites where wall wraps are exposed to mechanical damage from fixings, tools, and rough handling during cladding installation. Woven wraps are specified on commercial and industrial buildings and on residential projects where the construction programme involves extended exposure before cladding is applied.
