Dow Styrofoam CM Spray Polyurethane Foam

STYROFOAM SPF Insulation (CM Series) is a professionally applied two-component, polyurethane foam that creates a seamless, monolithic barrier for protection against water vapor and air on the interior of steel stud walls. This closed-cell, 2-pcf spray foam successfully incorporates an advanced blowing agent with zero ozone depleting potential.

Product Description

Styrofoam SPF Insulation is created from a unique polyol technology, which offers high foam yield and wide processing latitude. The closed-cell, 2 pcf foam expands during application to fill cavities, cracks and crevices, blocking the uncontrolled air leakage that can threaten consistent, comfortable indoor temperatures.
