Installation Sheet: Reflective Foil Basement Wall Insulation

Basements are heat sinks. The outside earth constantly pulls heat from the interior causing a loss in radiant heat. Insulating basements are often over looked and cause valuable heat loss, especially if the area is heated. Reflective foil insulation is the ideal product for these applications.

InfraStop® Double Bubble Foil Insulation helps to reduce basement dampness and increase comfort. It reduces heat loss to the surrounding environment. InfraStop® is an excellent vapor and radon barrier. It's quick, safe, and easy to install and adds R-value. And unlike fiberglass insulation which loses its effectiveness with any moisture gain, InfraStop® is unaffected by moisture and humidity making it the perfect choice in basement applications.
