This wrap can protect your home from rainwater even before cladding is installed. How so? Well, it’s due to the maximum defense feature. This means that it won’t tear.


This DuPont™ product is made from non-woven, non-perforated, and high-density polyethylene fibers. These are fused together to create a uniform web. This web creates tiny pores that are resistant to water and resists air penetration too. All of this while permitting vapor to pass through. Since Tyvek is a non-woven house wrap, this does mean that it allows moisture vapor to escape. This does mean that it simultaneously keeps the air and water out of your wall.
