Structural Insulated Sheathing (SIS)

DOW SIS Plus is a sheathing product that combines structural, insulative, and weather barrier properties into one material. These properties are obtained by attaching a structural sheathing material to a polyisocyanurate insulation and adding a resilient exterior skin. The product is designed to help reduce thermal bridging.
