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
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
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.
