Shop for insulation products at NEG and Karpp, and find a full line of fiberglass, cellulose, and mineral wool insulation solutions, including:

  • Rigid foam board insulation – made from polystyrene, polyisocyanurate, and polyurethane. Rigid foam board insulation must be covered with ½” of other materials (like gypsum board) or with weatherproof facing.
