DuPont™ Tyvek® ThermaWrap™ R5.0: An Insulating Blanket for Your Home
The exterior walls of most homes have insulation between the wood studs inside the wall. But because wood is a poor insulator, significant heat loss can occur through the studs. This is called thermal bridging. Tyvek® ThermaWrap™ R5.0 improves a home’s energy efficiency by providing a blanket of continuous exterior insulation over the walls and studs, reducing thermal bridging.
