DuPont Tyvek Weatherization Systems

DuPont Tyvek the protective material with more then 30 years of performance in millions of homes.

Wrapping a home or building in a weather-resistant barrier is not just good sense, it’s 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 mold, mildew and wood rot. The properties of DuPont™ Tyvek® do not support the growth of mold 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.
