What is a Drainable Housewrap?

A drainable housewrap, like HydroGap, incorporates both a water-resistive layer and a drainage gap, greatly facilitating water drainage from behind the exterior siding. Unlike typical housewraps, which provide only a water-resistive layer and can trap water behind siding, drainable housewraps provide a continuous drainage gap that allows water to quickly escape from the wall system, protecting the building enclosure.

There is growing recognition that walls systems need to drain, and housewraps will increasingly be judged by how effectively they drain bulk water from the wall.

HydroGap Drainable Housewrap provides a much higher and more constant drain rate than standard housewraps. Compared to standard housewraps, HydroGap is 100 times more effective at removing bulk water from the wall.
