Tyvek® Advantages


Why is Tyvek® the leading housewrap?
You won't find any holes in our success story.
DuPont not only invented Tyvek®, we invented housewrap. And today, more homes are wrapped in Tyvek® than any other brand.

Tyvek® performs.
DuPont developed a nonwoven fabric structure that not only resists airflow and water penetration, but it breathes, too. Moisture vapor can pass through… without perforations!

Tyvek® protects.
Because Tyvek® has no holes, it protects your framing and sheathing better during construction. Tyvek® helps minimize damage from water leaks after the sale, and helps protect you from expensive callbacks. And Tyvek® is protected by a comprehensive DuPont guarantee.
