FOAMULAR XPS ROOF INSULATION FOR COMMERCIAL BUILDINGS PAGE 9 SINGLE-PLY ROOFING SYSTEMS Single-ply roofing membranes are flexible sheets of compounded synthetic materials that are manufactured in a factory. Single ply roof systems provide strength, flexibility, durability and installation speed. The inherent advantages of single-ply systems is the consistency of the quality of the plant manufactured membrane, and the versatility of product types, installation and attachment methods, all resulting in broader system appeal. Single-ply systems are different than another common category of roofing known as BUR (built up roofs), which utilize alternating layers of hot asphalt and reinforcing fabrics to construct a roof in place. FOAMULAR THERMAPINK XPS RIGID INSULATION FOAMULAR THERMAPINK XPS insulation is an excellent insulation choice for single-ply roofing systems. THERMAPINK XPS insulation, with a variety of compressive strengths, high resistance to water absorption, and a stable long term R-value of 5 per inch, is an excellent insulation layer for use below single-ply membrane roofing systems. Membrane systems vary in color and chemical composition, and may be mechanically attached, loose laid/ ballasted or fully adhered. Depending on the type of system specified, cover boards or slip sheets may be required over FOAMULAR THERMAPINK XPS insulation. Single-ply systems with THERMAPINK XPS insulation have a wide variety of UL and FM performance ratings for fire and wind resistance including ASTM E108 Class A, FM 4450 Class I, UL 1256 direct to steel deck with no thermal barrier layer, and, 90 psf and higher wind classifications. See pages 7 and 8 for FOAMULAR THERMAPINK insulation physical properties and size availability.
