DuPont™ Tyvek® HomeWrap® is the original house wrap and is specifically designed for proper moisture and air management within wall systems. Tyvek® HomeWrap® is a uniquely engineered product made by spinning extremely fine high-density polyethylene (HPDE) fibers that are fused together to form a strong, uniform web. The tough structure of Tyvek® is engineered to create millions of extremely small pores that resist bulk water and air penetration, while allowing moisture vapor to pass through. Because the unique nonwoven structure of Tyvek® HomeWrap® makes it breathable, this helps promote drying in wall systems, to help prevent mold and water damage. In addition, Tyvek® HomeWrap® stops air movement through the walls which helps insulation perform closer to its full R-value and provides a more energy-efficient home.

Tyvek® HomeWrap® is easy to handle, light weight and fast to install. When you choose to install Tyvek® HomeWrap® you are supported by your local DuPontTM Tyvek® Specialist and the building science resources of DuPont. Your local Tyvek® Specialist offers on-site consulting, training and help with the latest updates on building codes. 
A superior air and water barrier is an integral part of a home that’s built for lasting comfort and energy efficiency. Whether you are building a new home or residing and remodeling an existing home, installing Tyvek® HomeWrap® will help protect your investment.
