DuPont Introduces Revolutionary Insulated, Breathable Air and Water Barrier Building Wrap

DuPont™ Tyvek® ThermaWrap™ R5.0 Boosts R-value While Reducing Risk of Mold and Water Damage

Dupont 1WILMINGTON, Del., Nov.6, 2013 – 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.

Based on sophisticated building science, DuPont™ Tyvek® ThermaWrap™ R5.0 delivers 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®. Like all Tyvek® building wraps, Tyvek® ThermaWrap R5.0 helps keep air and bulk water out of walls, but is breathable, allowing moisture vapor to escape the wall assembly, which helps walls dry to the outside.

Dupont 3DuPont™ Tyvek® ThermaWrap™ R5.0 will offer another insulation option to builders seeking to construct above-code, more energy-efficient homes as they work to achieve the higher wall R-values required by the most recent versions of the International Energy Conservation Code (IECC). This also can be done without dramatically changing current building practices.

“This product is the only one of its kind on the market,” said Angela Strzelecki, North America business director, DuPont Building Innovations. “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. At the same time, DuPont™ Tyvek® ThermaWrap™ R5.0 can help builders meet or exceed increasingly stringent codes, standards and home certification programs. ”

Dupont 2As a leader in energy-efficient building, Schottenstein Homes of Columbus, Ohio was among the first builders to install this new product on a single-family home in their new subdivision in the Hilliard area.  “Although current codes for our market do not require the use of exterior insulation, our builders are aware that they will soon be dealing with that requirement.  I am very excited about this new product from DuPont™ and I am looking forward to working with the builders in Central Ohio to provide a solution to upcoming code changes,” said Ann Misiolek, Senior Certified DuPont™ Tyvek® Specialist for Parksite, the local distributor of the DuPont™ Tyvek® Weatherization products.
