Division 7 Ebook Page 247 Low Slope Commercial Roofing Overview

Section Overview Low Slope Single-Ply Insulated Roof Systems 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 Extruded Polystyrene (XPS) Rigid Insulation FOAMULAR THERMAPINK XPS is a perfect 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 a perfect insulation layer for use below single-ply membrane roofing systems. Membrane systems vary in color and chemical composition, and, they 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 Underwriters Laboratories (UL) and Factory Mutual (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. Sustainability Owens Corning is committed to driving sustainability through greening our operations, greening our products and accelerating energy efficiency in the built environment. Owens Corning FOAMULAR XPS products, are GREENGUARD Indoor Air Quality Certified and GREENGUARD Children and Schools Certified SM . FOAMULAR XPS is also third party certified, to contain a minimum 20 percent recycled polystyrene content and is produced with a zero ozone depletion blowing agent formulation.
