Tyvek HomeWrap

Tyvek® HomeWrap® is a weatherization membrane that provides a protective layer under a home’s siding and over the sheathing. It is literally wrapped around a home over the wood or foam sheathing, cut out around windows and doors and taped at the seams.

The unique, nonwoven-fiber structure of Tyvek® HomeWrap® resists air infiltration and water intrusion, yet is engineered to readily allow moisture vapor to diffuse through the sheet, helping prevent mold and mildew buildup and wood rot. The fibrous structure is engineered with microscopic pores that readily allow moisture vapor to evaporate but are so small that bulk water and air cannot penetrate. Siding, whether it’s vinyl, wood, stucco, brick, or composite, does not completely prevent air and water penetration. Tyvek® is designed as a secondary defense to help manage a home’s wall systems.
