Unless otherwise noted, all Insulations are Flat stock or taper board of the minimum thickness noted. Tapered polytsocyanurete at the following thickness limitations may be substituted with the following Maximum Design Pressure (MDP) limitations. In no case shall these values be used to 'increase' the MOP listings in the tables; rather if MOP listing below meets or exceeds that listed for a particular system in the tables, then the thinner board listed below may be used as a drop -in for the equivalent thicker material listed in the table: D JM One -Step Foamable Adhesive [JM-OSFA]: MDP: -157.5 psf (Min. 0.5-inch thick) D JM Roofing System Urethane Adhesive (1M RSUA): MOP -157.5 psf (Min. 0.5-Inch thick) D JM Two -Part Urethane Insulation Adhesive[UTA-TWO-PART]: MDP:-315.Opsf (MIn.0.5-Inch thick ENRGY 3 orJM ISO 3) ICP Adhesives CR-20 [CR-20]: MOP: -117.5 psi (Min. 1.G-Inch thick) 8. Bonded polyisocyanurete insulation boards shall be maximum 4 x4 ft. 9. For mechanically attached components or partially bonded insulation, the maximum design pressure for the selected assembly shall meet or exceed the Zone 1 design pressure determined In accordance with FBC Chapter 16, and Zones 2 and 3 shall employ an attachment density designed by a qualified design professional to resist the elevated pressure criteria. Commonly used methods are ANSI/SPRI WDl, FM Loss Prevention Data Sheet 1-29, Roofing Application Standard RAS 117 and RAS 137. Assemblies marked with an asterisk- carry the limitations set forth in Section 2.2.10.1 of FM Loss Prevention Data Sheet 1-29 (January 2016) for Zone 2/3 enhancements. 10. For assemblies with all components fully bonded in place, the maximum design pressure forthe selected assembly shall meet or exceed critical design pressure determined in accordance with FBC Chapter 16, and no rational analysts is permitted. 11. For mechanically attached components over existing decks, fasteners shall be tested in the existing deck for withdrawal resistance. A qualified design professional shall review the data for comparison to the minimum requirements for the system. Testing shall be in accordance with ANSI/SPRI FX-1 orTesting Application Standard TAS 105. 12. For existing substrates in a bonded recover or re -roof installation, the existing roof surface or existing roof deck shall be examined for compatibility and bond performance with the selected adhesive, and the existing roof system (for recover) shall be capable of resisting project design pressures on Its own merit to the satisfaction of the Authority Having Jurisdiction, as documented through field uplift testing in amordance with ANSI/SPRI IA-1, ASTM E907, FM Loss Prevention Data Sheet 1-52 orTesting Application Standard TAS 124. 13. For System Type D, steel deck applications, the roof membrane shall be run with its length perpendicularto the steel deck Flutes. 14. For Recover Applications using System Type D, the Insulation is optional. Alternatively, Invinsa Roof Board, DensDeck, DensDeck Prime, DEXCell FA Glass Mat Roof Board or SECUROCK Gypsum -Fiber Roof Board may be used as a separator board, preliminarily attached prior to roof cover Installation. The existing roof system shall be suitable for a recover application. 15. LWIC shall be cast In accordance with FBC Section 1917 to the satisfaction of the Authority Having Jurisdiction. For systems where specific LWIC Is referenced, refer to current LWIC Product Approval for specific deck construction and limitations. For systems where specific LWIC is not referenced, the minimum design mix shall be 300 psi. In all cases, the minimum top -coat thickness Is 2-Inches. For LWIC over structural concrete, reference Is made to FBC Section 1917.4.1, Point 1.
