Armatherm™ 500 Series Foundation Wall Thermal Bridging US

Foundation Wall Thermal Bridging Solution

Thermal Bridging at foundation wall transitions creates heat loss at the foundation perimeter. This reduces the exterior wall’s effective R Value. Foundations are part of a  buildings’ thermal envelope. The intersection at a slab on grade to  foundation wall and exterior wall to foundation transition are both areas where heat flows out of a building. This is due primarily to non-continuous insulation details.

Foundation Wall Thermal Break

The linear transmittance (heat loss) at the base of the foundation wall can be reduced by as much as 60% by using an efficient, structural thermal break. Armatherm™ 500 is a load bearing, thermal break material manufactured in several densities to provide a range of load capacities with R values as high as R 3.8 per inch.

Thermal bridging at a foundation wall transition can be reduced further by increasing the length of the slab insulation.
