Structural Insulated Sheathing (SIS) from DOW

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 composed of recycled content to a polyisocyanurate insulation and adding a resilient exterior skin. The product is designed to help reduce thermal bridging, and eliminate the need for separate house wrap.
