Tyvek® Building Envelope Weatherization Systems

DuPont™ Tyvek®—the protective material with more than 30 years of performance in millions of homes.

Wrapping a home with a weather-resistant barrier is good building practice because it helps combat water, moisture and air infiltration that are any structure’s worst enemies. Allowed to penetrate behind siding, wind-driven rain and moisture can saturate walls, creating a breeding ground for mould, mildew and wood rot. The properties of DuPont™ Tyvek® do not support the growth of mould or mildew.

Air infiltrating from outside can create comfort-robbing cold or warm spots while increasing heating and cooling costs.  DuPont™ Tyvek® acts like a windbreaker and wrapped over the sheathing and under the exterior siding—cut out around windows and doors and taped securely at the seams—resists air infiltration and water intrusion and makes for a more comfortable, energy-efficient home or building.

Whether you’re building new, renovating or re-siding, ask your construction professional or your home improvement retailer for these products and other miracles of science in the DuPont Weatherization Systems family of products.
