DuPont™ Tyvek® ThermaWrap® R5.0 Helps Home Achieve Energy Star® Tier 3 and HERS Target Ratings

December 20, 2016

TNT General Contracting chose to use Tyvek® ThermaWrap® R5.0 on a new residential home in Belchertown, MA.


To create a comfortable home large enough for a family of four that would qualify for an Energy Star® Tier 3 rating to help keep energy costs affordable.


In order to realize the HERS and Energy Star® Tier 3 ratings, it was necessary to find a product that provided continuous exterior insulation of at least R-5 while still allowing the house to breathe without adding a lot of cost for installation.


DuPont™ Tyvek® ThermaWrap® R5.0 provided a continuous thermal break around the entire exterior of the house and provided the weatherization properties of regular DuPont™ Tyvek® HomeWrap®. The installation team was able to save installation time vs. installing a foam alternative. The HERS rating on the home registered at 38 providing the family with the energy savings necessary to fit their budget.

“DuPont™ Tyvek® ThermaWrap® R5.0 is one of the only exterior thermal products that I could find that provided a true thermal break on the entire exterior of the house while still allowing it to breathe properly. It was extremely easy to install.”
