Residential Air and Water Barriers

Superior Air and Water Barrier Systems for Homes

Build in durability and energy efficiency with Tyvek® weather barriers that help keep air and water out, and let buildings breathe.

A superior air and water barrier is an integral part of a home that’s built for lasting comfort and energy efficiency. DuPont Building Envelope Systems help control airflow through walls, while holding out bulk water, and allowing moisture vapor to escape.

Our integrated family of products, starting with DuPontTM Tyvek®, weather barriers, are backed by sophisticated building science that delivers superior performance, from UV resistance to vapor permeability. They are rigorously tested to meet or exceed industry performance standards and building and energy codes, and are backed by a limited warranty. 

DuPont invented the air and water barrier category more than 30 years ago. Today, Tyvek® weather barrier systems are enhancing quality, comfort and ROI in new construction and remodel/reside projects.
