    • Our take on the Foam Sheet, Water-Resistant Closed Cell

    This is a 2-inch-thick, 18 by 24 inch gray polyethylene foam sheet with closed cells, so it resists water and won't soak up spills. It meets military spec A-A-59136 Type 1 Class 1 Grade A, which sets its density at 2.2 lb/cu ft and its firmness at 9 psi at 25 percent deflection. That makes it a firm, dense foam rather than a soft cushion, suited to padding, packing, insulation and impact protection. Compared with cheap white packing foam, it holds up better under load and moisture, but it is heavier and stiffer than EVA or polyurethane foams used for comfort padding.

    Questions and answers

    What is closed-cell foam good for?
    Closed cells keep water and air from passing through, so it suits padding, packing, insulation and sealing where moisture is a concern. It also holds up better than open-cell foam under repeated pressure.
    How firm is this foam?
    It takes 9 psi to compress it 25 percent, which is a firm, dense foam. It supports weight and absorbs impact but is not soft enough for cushions or mattresses.
    Can I glue it to a surface?
    It has a plain backing with no adhesive. You can bond it with a spray adhesive or contact cement made for polyethylene, or hold it in place mechanically.
    What does the military spec mean?
    A-A-59136 Type 1 Class 1 Grade A sets requirements for density, firmness and cell structure. Meeting it means the foam is consistent from sheet to sheet.
    What temperature can it handle?
    It is rated from -20 to 150 degrees F. Keep it away from direct heat sources above that range.
    How big is the sheet?
    It is 18 inches by 24 inches and 2 inches thick, so one sheet covers 3 square feet of surface.
    Where is the Foam Sheet, Water-Resistant Closed Cell cheapest?
    At The Tools Man, for $24.47, as of our latest check.
