HydroGap Drainable Housewrap (5' x 100')

The Ultimate Moisture Management Solution for High-Performance Exteriors.

HydroGap is the most efficient drainable housewrap on the market, engineered to provide a continuous drainage path for water behind your siding. By creating a dedicated space for moisture to escape, it prevents rot, mold, and degradation, ensuring your home’s envelope stays dry and protected for decades.

Why Choose HydroGap?

Standard housewraps can sometimes trap water against the sheathing due to surface tension. HydroGap solves this with its patented 1mm compression-resistant spacers, which create a drainage gap that sheds water up to 2x faster than traditional weather-resistive barriers (WRBs).

Key Features

True Drainage Path: The 1mm spacers ensure that even if siding is nailed tightly, water can still flow freely down the wall.

Superior Breathability: With a high perm rating, it allows interior moisture vapor to escape, preventing "sick building syndrome."

Omni-Directional Installation: Can be installed in any direction without affecting the drainage flow, reducing waste and installation time.

Versatile Compatibility: Perfect for use under fiber cement, composite siding, engineered wood, and even cedar shingles.

Durability: UV-stable for up to 120 days, allowing for flexibility in construction schedules.
