Underlayments

Housewrap and Roof Underlayment optimize home building.

Gorilla Wrap(TM) non-perforated, nonwoven, polymeric housewrap minimizes air infiltration, resulting in energy efficiency and moisture control. Translucent material offers tear resistance and enables contractors to see studs, nails, and windows on home's frame. Employing asphalt with nonwoven polyester reinforcement, DuraBase(TM) underlayment provides puncture resistance and waterproofing as it...
