    Q:Will this help for noise cancelling?
    by|May 27, 2024
    1 Answer
    Answer This Question

    A:  Hello Water, Foamular does not have any soundproofing properties. Foamular Extruded Polystyrene Insulation contributes little to the acoustical design of interior spaces. Two primary concerns exist in the acoustical design of interior space: control of reflected or reverberant sound within a room, and control of transmission of externally generated sound through a wall or other assembly into a room. Foamular Extruded Polystyrene Foam is a thermal not an acoustical insulation. It is neither an effective sound absorber nor a sound blocker. Foamular Insulation is not recommended for exposed use in interior spaces; once covered with a thermal barrier such as ½” gypsum board, the sound absorption properties of Foamular Insulation become irrelevant. Reducing sound transmission through a wall or roof assembly depends on the mass, stiffness, and air-tightness of the assembly and on filling the wall cavity with a porous, low density material that will absorb sound, an application for which fiber glass is ideal. Low density plastic insulation such as extruded polystyrene foam contributes little to either sound transmission or absorption in wall and floor/ceiling assemblies. Thank you for your inquiry!

        Q:Is it a good idea to use this to insulate a 16x7ft metal garage door?
        by|May 10, 2024
        1 Answer
        Answer This Question

        A:  Hello Arch, Owens Corning Foamular products are combustible and must be covered by a 15-minute thermal barrier such as 1/2" drywall. We do not recommend using Foamular to insulate a garage door. There are better choices such as the Owens Corning Garage Door Insulation Kit. Thank you for your inquiry!

          I used this as a pad to assist me with getting a level pad for my above-ground pool. I saw someone do this on YouTube, and it really helped me. Home Depot delivered the 6 boards that I needed (79$ for delivery, that was a little steep but the alternative of renting a truck…). They are pre-scored and that saves a lot of time and effort cutting, and keeping square. This is a nice surface for my pool bottom. Great results.

          I live in a concrete block home in Indiana. The inside walls are stick built against the blocks. Using this between the studs and we have half of the house done and our electric bill has dropped significantly. Can't wait to get this out into the other half of the house to see what our bill will be then. ?

          Worked great for creating a backing for a standing photo wall. Thick enough and not too flimsy, but also sturdy and not as heavy as wood.
