HydroGap® SA is the first and only self-adhered WRB to incorporate a true drainage space. As one of the best housewraps on the market, HydroGap® SA reduces the risk of moisture damage by keeping walls dry. The self-adhered component of this product helps limit the amount of air that passes through the membrane.

The 1mm spacer technology combined with a fully continuous breathable acrylic adhesive provides an unmatched air and moisture barrier. Additionally, this drainable housewrap has a mesh-like material that increases the tear resistance and improves the flexibility and stretch of the product when tension is applied. The features, benefits, and ease of installation make HydroGap® SA a favorite among contractors for residential and multi-family builds.
