Thermal bridging is the movement of heat across an object that is more conductive than the materials around it. The conductive material creates a path of least resistance for heat. Thermal bridging can be a major source of energy loss in homes and buildings, leading to higher utility bills. Thermal Bridging in Homes
A significant thermal bridge can be created in residential home construction by the studs in the wall. American homes have traditionally been built with 2x4 wood studs spaced 16” on center, with fiberglass batt insulation added to the cavity. Although the fiberglass insulation may have an r-value of R-15 or more, it can only be placed in between the wood studs. These studs are more conductive than the fiberglass insulation surrounding them, so although the insulation reduces energy loss through the wall, it does not stop energy loss across the thermal bridge. Nearly 25% of a home’s wall is made of wood studs. Even if you have fiberglass insulation in the cavity, it adds up to one whole wall of the home with zero insulation. As you are paying to make your home comfortable, 25% of your walls are working against you.
