DuPont™ Tyvek® HomeWrap®
Sturdy Housewrap Engineered for Energy Efficiency
<br><b>DuPont™ Tyvek® HomeWrap®</b> is the original house wrap, leveraging advanced material science to keep air and water out while allowing water vapor to escape. This contributes to enhanced building durability by protecting homes from damaging wind and rain that can penetrate exterior cladding.
<br><br>
<b>Tyvek® HomeWrap®</b> is uniquely engineered by spinning extremely fine high-density polyethylene (HDPE) fibers that are fused together to form a strong, uniform web. This robust structure creates millions of tiny pores that resist bulk water and air penetration while allowing moisture vapor to pass through.
<br><br>
Additionally, <b>Tyvek® HomeWrap®</b> can reduce home energy bills by controlling air flow and water intrusion, thereby improving insulation performance and HVAC efficiency. It is designed to keep homes cool in the summer, warm in the winter, and dry all year round.
