<br /> 7. Unless otherwise noted,all insulations are flat stock or taper board of the minimum thickness noted. Tapered polyisocyanurate at the following thickness limitations maybe substituted with the following Maximum
<br /> Design Pressure(MDP)limitations. In no case shall these values be used to`increase the MDP listings in the tables;rather if MDP listing below meets or exceeds that listed for a particular system in the tables,then
<br /> the thinner board listed below may be used as a drop-in for the equivalent thicker material fisted in the table.
<br /> ➢ Hot Asphalt(HA): MDP= -240.0 psf (Min.05-inch thick)
<br /> ➢ GAF 2-Part Roofing Adhesive(GAF 2-Part): MDP= -117.5 psf (Min.1.0-inch thick)
<br /> ➢ LRF Adhesive M(LRF-M): MDP= -2325 psf (Min. 05-inch thick EnergyGuard Polyiso Insulation, EnergyGuard NH Polyiso Insulation, EnergyGuard Ultra Polyiso Insulation,
<br /> EnergyGuard NH Ultra Polyiso Insulation)
<br /> ➢ OlyBond 500(OB500): MDP= -315.0 psf (Min.OS-inch thick EnergyGuard RH or RN)
<br /> ➢ OlyBond 500(OB500): MDP= -4875 psf (Min.0.5-inch thick EnergyGuard RA)
<br /> ➢ OlyBond 500(OB500): MDP= -2925 psf (Min. 05-inch thick EnergyGuard Polyiso Insulation, EnergyGuard NH Polyiso Insulation, EnergyGuard Ultra Polyiso Insulation,
<br /> EnergyGuard NH Ultra Polyiso Insulation)
<br /> 8. Bonded polyisocyanu rate insulation boards shall be maximum 4 x 4 ft.
<br /> 9. Perimeter and comer areas shall comply with the enhanced uplift pressure requirements of these areas. Fastener densities shall be increased,as calculated in compliance with Roofing Application Standard RAS 117
<br /> and/or RAS 137 6y a qualified design professional. *This extrapolation is nor permitted forsystems marked with an asterisk'".
<br /> 10. For assemblies marked with antasterisk*,the maximum design pressure(MDP) limitation listed shall be applicable to all roof pressure zones(i.e.,field, perimeters and comers). Neither rational analysis, nor
<br /> extrapolation is permitted for enhanced attachment at enhanced pressure zones(i.e.,perimeters,corners and extended corners).
<br /> 11. Fastener spacing for mechanical attachment is based on a minimum fastener resistance value in conjunction with the maximum design pressure(MDP)listed for a specific system. Should thefastener resistance be
<br /> less than that required,as determined by the Building Official,a revised fastener spacing—prepared,signed and sealed by a qualified design professional—may be submitted. Said revised fastener spacing shall utilize
<br /> the withdrawal resistance value taken from Testing Application StandardTAS'105 and calculations in compliance with Roofing Application Standard RAS 117 or RAS 137.
<br /> 12. For bonded insulation or membrane over existing substrates in a recover installation,the existing roof system shall be capable of resisting project design pressures on its own merit to the satisfaction of the Authority
<br /> Having Jurisdiction,as documented'through field uplift testing in accordance with Testing Application Standard TAS 124.
<br /> 13. For System Type D,steel deck applications,the roof membrane shall.be run.with its length perpendicularto the steel deck flutes.
<br /> 14. For.recover installations,the existing roof shall be examined in accordance with FBC 1521. For Recover Applications using System Type C-2 or or any-System Type D,the insulation is optional. Alternatively,a
<br /> separator board may be installed priorto roof cover installation when using System Type C-2 or any System Type D or a separator sheet may be installed prior to roof cover installation when using any System Type D.
<br /> The separator component shall be documented as meeting FBC(HVHZ)1516 and,forfoam plastic,FBC Chapter 26,when installed with the roof cover in Recover applications.
<br /> ➢ Separator Board Options for Recover System Type C-2 or System Tvpe D: Min.0.5-inch EnergyGuard Polyiso Insulation,EnergyGuard NH Polyiso Insulation,EnergyGuard RA,EnergyGuard RN,EnergyGuard Ultra
<br /> Polyiso Insulation,EnergyGuard NH Ultra Polyiso Insulation,Structodeck High Density Fiberboard Roof Insulation,EnergyGuard RH HD Polyiso Insulation,EnergyGuard HD Polyiso Insulation,EnergyGuard NH HD
<br /> Polyiso Insulation,EnergyGuard HD Plus Polyiso Insulation or EnergyGuard NH HD Plus Polyiso Insulation,or min;0.25-inch Dens Deck,Dens Deck Prime,SECUROCK Gypsum-Fiber Roof Board orSECUROCK Glass-
<br /> Mat Roof Board.
<br /> ➢ Separator Sheet Options for Recover System Type D: EverGuard Polymat Separation Layer(3 oz/yd2)or EverGuard Polymat Cushioning Layer(6 oz/yd).
<br /> 15. For systems,where specific lightweight insulating concrete(LWIC)is referenced, refer to current LWIC Product Approval for specific deck construction and limitations. Unless otherwise noted,for systems where
<br /> specific LWIC is not referenced,the minimum design mix shall be 300 psi.
<br /> 16. Side laps for EverGuard Freedom TPO with RapidSeam Tech nology,a re self-adhering. Side laps for.EverGuard Freedom TPO,HW are heat welded. Unless otherwise noted,reference to EverGuard Freedom TPO in this
<br /> Appendix relates to either method.
