Page 8 of 13 - As part of a Roof Deck Construction for interior fire exposure as specified in Section 2603.4.1.5 of the IBC. See Section 7.2 for a link to the UL Online Certifications Directory for Roof Deck Constructions for assemblies UL Classified in accordance with UL 1256 incorporating FOAMULAR XPS insulation boards. Recover and Reroofing: New roofing must not be applied over existing roof-covering systems except in compliance with Section 1510 of the IBC and Maintenance & Repair systems as referenced in UL Classified systems described in Section 7.2 of this report. The fire performance of a roof system is directly affected by the materials covering the foam plastic insulation. The components of the existing roofing that are to remain on the roof deck must be inspected in accordance with IBC Section 1510 or IRC Section R907. Unless listed as a Maintenance and Repair system the existing roof-covering membrane and, if necessary, the cover board must be removed before new roofing materials are installed; the new roofing materials must have characteristics specifically described in this report. 6.4 Use in Fire-Resistance Rated Wall and Roof-Ceiling Construction: FOAMULAR XPS insulation boards are used as part of fire-resistance rated wall construction and roof- ceiling construction as specified in Chapter 7 of the IBC or Section R302 of the IRC. See Section 7.2 of this report for a link to the UL Online Certifications Directory for Fire-Resistance designs UL Classified in accordance with UL 263 incorporating FOAMULAR XPS insulation boards. 6.5 Use in Attics and Crawl Spaces: FOAMULAR XPS insulation boards may be used on walls of attics and crawl spaces, without the coverings listed in Section 2603.4.1.6 of the IBC or Sections R316.5.3 and Section R316.5.4 of the IRC, as follows: 1. Entry to the attic or crawl space is limited to service of utilities, and no storage is permitted. Utilities include, but are not limited to, mechanical equipment, electrical wiring, fans, plumbing, gas or electric hot water heaters, and gas or electric furnaces. 2. There are no interconnected crawl space areas 3. Air in the attic or crawl space is not circulated to other parts of the building. 4. Under-floor (crawl space) ventilation is provided when required by Section 1203.3 of the IBC or Section R408.1 of the IRC, as applicable. 5. Combustion air is provided in accordance with International Mechanical Code(IMC) Sections 701 and 703 (2006 IMC) or Section 701 (2012 and 2009 IMC). 6. Foamular XPS insulation boards are limited to a maximum thickness of 3 inches (76.2mm) and a maximum density of 2.0 pcf (32 kg/m 3 ). 6.6 Use Without a Thermal Barrier FOAMULAR XPS insulation boards with a maximum thickness of 2 in. and a maximum density of 1.80 pcf, may be installed on any or all surfaces (wall, ceiling, floor) of a detached garage, pole barn, telecommunication shelter, concrete modular building, agricultural building, buildings under the IBC Utility and Miscellaneous Group U or other structures under the IBC or IRC, with no thermal or ignition barrier applied to the foam plastics, based on testing in accordance with NFPA 286, and IBC Section 2603.10 or IRC Section R316.6, when all other requirements of the building code for that building are met.
