Wilmington, Del.-based DuPont Building Innovations launched DuPont Tyvek ThermaWrap R5.0, a building wrap that acts as a breathable air and water barrier, while providing continuous exterior insulation.

This new addition to the DuPont product portfolio helps builders achieve higher R-value wall assemblies, improving energy efficiency while helping to reduce the chance of water accumulation in the wall, which can lead to mold and water damage that may occur when using other non-vapor permeable exterior insulation products, according to the company.

“We recognized the need for a product that can be installed like a building wrap, and provide builders a level of insulation to help improve energy efficiency and air and water protection to improve the durability of their homes," said Angela Strzelecki, North America business director, DuPont Building Innovations. "At the same time, DuPont Tyvek ThermaWrap R5.0 can help builders meet or exceed increasingly stringent codes, standards and home certification programs. ” 

The product claims to deliver the benefits of a weather barrier along with an insulation value of R5.0 in a single, integrated product that can be installed using familiar installation techniques similar to those for DuPont Tyvek HomeWrap.
