Q:What is the STC rating on 1” polly urathane
by|Oct 19, 2023
1 Answer
Answer This Question

A:  Hello BobZ, Owens Corning products do not have a STC rating. They can contribute to an assemblies STC Rating. The amount they contribute can vary based on the other components in the assembly. However, Foamular does not have any soundproofing properties. Foamular Extruded Polystyrene Foam is a thermal not an acoustical insulation. It is neither an effective sound absorber nor a sound blocker. Thank you for your inquiry!

    Q:Can this foam insulation be painted?
    by|May 18, 2023
    1 Answer
    Answer This Question

    A:  Hello bear, if the Foamular is being used for crafts then it can be painted with latex paint. If the Foamular is being used as a building material, painting would not be an acceptable cover for the product. Foamular is a combustible product and must be covered with a 15-minute thermal barrier when being used as a building material. Thank you for your inquiry!
