EnergyGuard Tapered PolyIso Insulation
EnergyGuard Tapered PolyIso Foam Roof Insulation has a thermally efficient polyisocyanurate core bonded between organic/glass facers. It is readily available in the two most popular and efficient tapers, 1/8 inch per foot (1%) and 1/4 inch per foot (2%).
- Properly designed and installed, EnergyGuard Tapered PolyIso Foam Insulation Systems virtually eliminate ponding water.
- High thermal efficiency.
- Easily installed with mechanical fasteners, hot asphalt or loose laid in a ballasted system.
- Low point and letter codes are designated on each board.
- Engineering design board layouts are available from your plans and field verified dimensions.
- EnergyGuard Tapered PolyIso Foam Roof Insulation is designed for use over structural roof decks to provide slope to drain and to provide thermally efficient insulation.
- When properly installed, it is suitable for use under built-up, modified bitumen, and most single-ply roofing systems.
- Refer to the membrane manufacturers current application and specifications manual for proper installation procedures.
Traffic/Storage/Potential Fire Hazard
- EnergyGuard Tapered PolyIso Foam Roof Insulation is a non-structural, non-load bearing board. It is not designed for direct traffic usage unless adequately protected.
- EnergyGuard Tapered PolyIso Insulation should be stored dry and be protected from the elements. Once properly loaded at the job site, remove factory wraps and cover with a breathable tarp.
- As an unprotected polyisocyanurate will burn, fire safety precautions must be observed wherever any insulation products are used.
- Direct torching of modified bitumen roofing to EnergyGuard Tapered PolyIso Foam Roof Insulation will present a fire hazard. A properly installed fiber glass base sheet MUST be used over the insulation.
- These tapered systems are designed to provide a top surface of slope. Each board is manufactured to exact thickness specifications. GAF cannot be held responsible for field conditions such as actual building dimensions and deck deflection.
Installation Suggestions for Tapered Systems
Although each tapered system is different, here are some suggested methods for installing a Tapered PolyIso Foam Roof Insulation system efficiently.
- Verify building dimensions and drain locations with the Tapered Foam Roof Insulation Shop Drawing. Discrepancies should be reported to GAF prior to shipment.
- Verify that the proper number of truckloads and piece quantities have been received on the job site.
- Determine the area to be completed that day.
- Measure the distance from the drain to the perimeter where the shop drawing indicates full 4 x 4 insulation boards. Verify that the system will meet the drain piece.
- Start installing the tapered system utilizing full 4 x 4 boards. Work from the drain and finish the area where the shop drawing indicates field cutting.
- When more than one layer of insulation is utilized, all vertical board joints should be staggered, preferably by 1/2 board.
- Cover the insulation with the complete membrane system the same day.
- Listed by Underwriters Laboratories for use under Class A, B, or C Roof Covering. See UL, ULC Inc. Roofing Materials and Systems Directory for details.
- Approved component of Factory Mutual System Class I, Insulated Steel Deck Construction when secured to the steel deck with mechanical fasteners (such as DRILL-TEC roof insulation fastener system).
- Mechanical attachment of roof insulation is the most dependable method of attachment to steel decks since it minimizes lateral movement and wind blow-off.'
- For details, consult Factory Mutual Loss Prevention Sheet 1-28, 1-29, 1-28R, 1-29R and Approval Guide.
- Federal Specifications HH-I-1972.
WARNING: DO NOT EXPOSE TO OPEN FLAME OR EXCESSIVE HEAT. MAY BURN IF IGNITED. IF IGNITED, EXTINGUISH COMPLETELY.
NOTE: REPAIR ROOF LEAKS PROMPTLY TO AVOID ADVERSE EFFECTS, INCLUDING MOLD.
