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.

About
Tyvek® ThermaWrap® R5.0
Tyvek® ThermaWrap® R5.0 offers the air and water management benefits of all Tyvek® weather barriers with an R-value of 5.0. benefits.

Compared to other exterior insulation products, the unique structure of Tyvek® ThermaWrap® R5.0 allows any moisture that may get inside the wall to dry and escape to the outside, helping to prevent the accumulation of water in the wall reducing the chance for water damage and mold.

This short video gives a fun explanation on thermal bridging and the benefits of
Tyvek® ThermaWrap® R5.0:
The below thermal images show two new houses, both built with interior wall insulation. The house on the left was built WITHOUT any exterior insulation. The house on the right was built WITH Tyvek® ThermaWrap® R5.0 continuous exterior insulation and weather barrier. The yellow vertical lines on the house without Tyvek® ThermaWrap® R5.0 shows heat loss through the studs. Note the lack of heat loss on the house with Tyvek® ThermaWrap® R5.0. This means improved energy efficiency and lower utilities bills.
An Insulating Blanket for Your Home

Wall studs account for up to 25% of every wall. The heat loss through the studs is the equivalent of having an entire side of the house completely uninsulated. That’s like keeping your windows and doors open with the heater or the air-conditioner on!

Tyvek® ThermaWrap® R5.0 fights thermal bridging by blanketing the outside of the wall and the studs with an R 5.0 continuous insulation, so that heat escaping through the studs can’t get out. This can help reduce energy bills by up to 25%!

Significant heat loss through the studs on a wall without exterior insulation beneath the cladding
With Tyvek® ThermaWrap® R5.0 on the exterior wall beneath the cladding heat loss through the stud to the outside is greatly reduced.
