ThermaSheath-SI is a composite (97% recycled) product made up of an insulation and structural component that is designed to work seamlessly with non-structural Rmax ThermaSeath. The insulation component is an energy-efficient thermal insulation board composed of closed-cell polyisocyanurate (polyiso) foam bonded to reflective, reinforced aluminum facers providing superior physical and thermal properties along with a durable radiant barrier surface. The structural component is a board made of fibered, specially treated plies that are pressure- laminated with a water-resistant adhesive.
