LEED Certification Resources

An extruded polystyrene foam (XPS), Styrofoam™ insulation is designed for use in residential and commercial construction and meets applicable requirements for fire, air and water-resistive barriers.

Thermax™ and Tuff-R™ insulation are both made polysocyanurate rigid foam and include glass fiber in the foam core for fire resistance. Thermax™ is used primarily in commercial construction, while Tuff-R™ is primarily for residential applications.

Made by combining equal parts of polymeric methylene-diphenyl diisocyanate and a polyol blend, spray polyurethane foam is designed to expand upon application to provide insulation and air sealing.

Tyvek™ Mechanically Fastened Air & Water Barrier Systems, based on flashspun high-density polyethylene, is used primarily in low-rise buildings and high-performance commercial buildings.

Made with proprietary polymer technology, Tyvek™ Fluid-Applied Weather Barrier Systems is designed to use when building geometry or application substrates preclude mechanically fastened barrier products.
