Typar's new HouseWrap DW is a high-performance housewrap engineered with continuous, multi-directional spacers that provide a drainage gap between the sheathing and the cladding. The material provides 96% drainage efficiency as measured by ASTM 2273 and exceeds AC 38 drainage specifications. The housewrap's design results in faster drainage and drier exterior walls, particularly in regions receiving significant annual rainfall. The maker says HouseWrap DW can remove 100 times more bulk water than standard housewraps. Check with your dealer for pricing. typar.com
