Products: High Performance Building Products: HydroGap Housewrap 1mm


Did you know that major siding manufacturers, such as James Hardie and Boral, have recently issued drainage requirements behind their products? Drainable housewraps with a drainage efficiency of at least 90% when tested according to ASTM E2273 are now recommended or required behind certain exterior sidings. 

Drainage efficiency isn't the whole story. We suggest that you question how long it takes to reach the 90% – how fast does your housewrap remove the moisture? The longer moisture remains trapped, the longer it has to cause mold, rot and premature failure. 

HydroGap Drainable Housewrap eliminates excess moisture in a matter of minutes and prevents the damaging effects of mold and rot. Its unique design provides up to two times the performance over other drainable housewraps and removes over 100 times more bulk water than standard housewraps.
