Guide for Use in Low Slope Roofing 1 Systems FOAMULAR THERMAPINK Extruded Polystyrene (XPS) Rigid Foam Insulation Notes and Details: 1. Must consult complete specifications for full product and system details. See www.foamular.com, the UL On-line Certifications Directory and FM RoofNav for complete system details. 2. Mechanically attached membranes are typically held in place with screws and stress plates. Fully adhered are held with adhesives or are self-bonding. Ballasted are loose laid, held down with dead weight of stones or pavers. 3. Typical structural deck type is noted. Concrete can be used in place of steel or vise-versa. 4. Concrete decks are a thermal (fire) barrier, therefore no need to add gypsum board. For steel deck, gyp board is not required for UL Const. #457. Gypsum board thermal barrier is required for all FM Class 1 steel deck systems using XPS. Gypsum board thermal barrier is also required for PRMA systems on steel deck. 5. Typical insulation choice is shown. Other THERMAPINK products may be used if specified. Thickness may be limited by FM or UL . 6. Cover layer may be board such as gypsum (GP DensDeck is common), or high density wood fiber. It may be mechanically attached or fully adhered per system specifications. Fabric slipsheets are needed for PVC membranes for chemical separation and fire rating (Sheet must be approved by PVC manufacturer. Atlas FR- 10 slipsheet can be used). Fabric slipsheet needed for TPO for fire rating (Altas FR-10 is common). For metal roofing, a cover board is required with a copper or black roof surface. 7. Approved Single Ply means approved by membrane manufacturer, and UL or FM, and installed in accordance with manufacturers and UL or FM system specifications. For recover roofing systems, the existing membrane may be BUR, modified bitumen or single ply. 8. Ballast weight, type and placement per design standard, ANSI/SPRI RP-4, Wind Design Guide for Ballasted Single-Ply Roof Systems.
