Suited for a wide range of applications, FOAMULAR extruded polystyrene (XPS) insulation is ideal for roofing applications including single-ply, protected roof membrane assemblies (PRMA), tapered, vegetative roofs, plaza decks, architectural metal roofing and recover roofing. For more information about the specific FOAMULAR insulation products below, please review each product's data sheet available at www. owenscorningcommercial.com or www.foamular.com. FOAMULAR THERMAPINK XPS insulation is an excellent insulation choice for single-ply roofing systems or architectural metal roofing. THERMAPINK 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 Underwriters Laboratories (UL) and Factory Mutual (FM) performance ratings for fire and wind resistance including ASTM E108 Class A, ASTM E119 hourly fire resistance, FM 4450 Class I, UL 1256 direct to steel deck with no thermal barrier layer, and 90 psf and higher wind classifications. THERMAPINK 25 insulation has a 25 psi compressive strength that is also strong enough to hold the retention clips used to secure metal roofing. Bearing plates under the clips sit into the surface of the insulation as they are tightened. No adhered facer means no extra labor needed to trim the surface to achieve proper seating. FOAMULAR XPS insulation products 404, 604, 404RB and 604RB are used in PRMA applications. FOAMULAR XPS insulation is the only insulation used in PRMA roof systems due to its excellent resistance to water absorption compared to any other type of rigid board insulation. Since the insulation is installed above the waterproofing membrane and is exposed to water through its service life, resistance to water while maintaining physical properties is critical. FOAMULAR 404 and 604 insulations have channels cut into the bottom edges on all four sides of the board to enhance drainage at the board/ membrane interface. FOAMULAR 404RB and 604RB insulations have ribs cut into the top surface of the board in addition to the channels on the bottom. The ribs serve as drainage enhancement under pavers when the pavers are laid directly on top of the foam board. This is in lieu of using pedestals to support and create drainage under the pavers. FOAMULAR DURAPINK XPS insulation is an excellent insulation choice for recover single-ply roofing systems. Unlike other cover boards sometimes used for recover, DURAPINK XPS insulation has high resistance to water absorption, maintaining all of its insulation and strength properties while any latent water that may be in the old system dissipates. DURAPINK recover insulation systems have a wide variety of UL and FM performance ratings including ASTM E108 Class A, and wind uplift resistance classifications. FOAMULAR Tapered Roof Insulation provides a thermally efficient, moisture-resistant positive drainage slope for use under single-ply or other types of roofing systems.
