Home Wrap Breathes, Provides Barrier


DuPont Building Innovations has introduced a home building wrap that acts as a breathable air and water barrier, while providing continuous exterior insulation.

DuPont Tyvek ThermaWrap R5.0 is the company’s latest addition to its portfolio of weatherization products.

The product delivers the benefits of a weather barrier along with an insulation value of R5.0 in a single, integrated product that can be installed in shingle fashion, the company said in a product announcement.

The wrap—made using 20 percent pre-consumer, recycled polymers—is further reported to help builders achieve higher R-value wall assemblies, improve energy efficiency and reduce the potential of bulk water accumulation in the wall, the company says.

Additional Features, Availability

The wrap has a Class A-flame spread and smoke-developed index rating with no added fire-retardant chemicals, DuPont said.

The system is currently available through DuPont Tyvek distributors and dealers east of the Mississippi. By the end of 2014, the wrap is expected to be available across the remainder of the United States and Canada.

Based in Wilmington, DE, DuPont Building Innovations, a business unit of DuPont, offers products and services for residential and commercial construction.
