Roof application:
|
KINGWAYTM vapor barrier breathable membranes are commonly use as waterproof underlay beneath the roof covering, which impervious to any wind driven rain or snow that gets blown through the roof covering, even when in direct contact with timber rafters and insulation. Meanwhile as they are vapor permeable, allow the roof structure to breathe, so the moisture from leakage and condensation can escape, to avoid mold and rot of fiberglass or cellulose insulation, so won’t lose its R-value due to heat-conducting moisture. |
