Closed Cell Foam Products - Closed Cell Spray Foam Insulation

Closed cell foam and sponge rubber products have been used for gasketing, cushioning, insulating, and padding applications for years. The number of options available can be daunting, but Insul-Fab sales engineers can help specify the right product for each application based on needs for compression deflection, compression set, temperature, flammability, oil resistance, UV resistance, and density.


Closed cell foam is what it sounds like. The cells are completely closed, which prevents air and moisture from getting through. Therefore, it gives closed foam more rigid and stable characteristics than open cell. Closed cell foam insulation helps provide structural integrity to buildings and is unaffected by water when they come in contact with each other.


  • Neoprene blends, PVC, vinyl/nitrile, polyethylene, EPDM, polyurethane, silicone, and more in split-thickness rolls and sheets or converted to end-use products.
  • Vertical integration of capabilities provides splitting, adhesive lamination, roll slitting, spooling, die-cutting, thermoforming, and water jet cutting.
