FOAMULAR® DURAPINK® Extruded Polystyrene (XPS) Rigid Foam Insulation Product Data Sheet Key Features • Excellent long-term stable insulation performance of R-5 per inch2 • Exceptional moisture resistance, long-term durability Energy-Saving, MoistureResistant XPS Insulation XPS Recovery Roofing Insulation ASTM C578 Type IV, 25 psi minimum Description DURAPINK® Roofing Recovery Board is an extruded polystyrene (XPS) roofing product designed for use with single-ply membranes, including black EPDM1 and other darkcolored single-ply membranes. DURAPINK® roofing recovery board works without overlay protection, ballast or pavers. DURAPINK® roofing recovery board saves the trouble and expense of removing the old roof, and adds insulation and moisture protection to the new one, providing new economy and durability for worn out commercial roofs. Roofing recovery is an increasingly popular means of reroofing for aged and trouble-plagued roofs. The decision to recover a roof is based on two compelling reasons: The cost involved in tearing off the old roof, and the cost of disposing of the discarded debris—both of which can be significant. When you recover, both costs are avoided. • Recommended for use directly under black EPDM membranes, without the need for protection. • Limited lifetime warranty3 — maintains 90% of R-value and covers all ASTM C578 properties • The only XPS foam to be GREENGUARD Children & Schools CertifiedSM • The only XPS foam with certified recycled content— certified by Scientific Certification Systems (SCS) to contain a minimum 20% recycled content • Will not corrode, rot or support mold growth • Zero ozone depletion potential with 70% less global warming potential than our previous formula • Reusable • Lightweight, durable rigid foam panels are easy to handle and install • Easy to saw, cut or score Technical Information: • DURAPINK® roofing recovery board is to be installed over existing roofs only and not over new insulation. • When installed beneath dark-colored, mechanically attached membranes, some vertical displacement may be noticeable, especially during the high heat of mid-day. Such behavior is normal thermal expansion and contraction of the material. The movement will not affect the integrity of the recover roofing membrane or attachment systems. • Recovery roofing is often done over uneven substrates. Humps, sharp edges or ridges in the existing membrane should be cut out if possible before covering with DURAPINK® roofing recovery board. If this is not possible, DURAPINK® roofing recovery board can be placed, but may crack over uneven surfaces when walked on. • Examine the existing roof for areas of wet insulation and/or wet or deteriorated decking. Remove and replace wet or deteriorated material as necessary. • All roofs to be recovered should be evaluated for the presence of an existing vapor retarder. Research by the Oakridge National Laboratory (ORNL) suggests that some wet roof systems containing permeable materials can be dried to the interior of a building if no internal vapor retarder is present. • When installing DURAPINK® roofing recovery board beneath a dark-colored, mechanically attached
