5.6.4 Wind Resistance for Underlayment Systems in Foam -On Tile Applications:.
FRSA/TRI April 2012 (04-12) does not address wind uplift resistance of all underlayment systems beneath
foam -on or mortar -set tile systems, where the underlayment forms part of the load -path. The following
wind uplift limitations apply to underlayment systems that are not addressed in FRSA/TRI April 2012 (04-
12) and are used in foam -on or mortar -set tile applications. Maximum Design Pressure is the result of
testing for wind load resistance based on allowable wind loads, and reflects the ultimate passing pressure
divided by 2 (the 2 to 1 margin of safety per FBC 1504.9 has already been applied). Refer to FRSA/TRI April
2012 (04-12), Appendix A, Table 1A or FBC 1609 for determination of design wind loads.

5.6.4.1 For mechanically attached Base Sheet, the maximum design pressure for the selected assembly shall meet
or exceed that required under FRSA/TRI April 2012 (04-12), Appendix A, Table 1A.
Alternatively, the maximum design pressure for the selected assembly shall meet or exceed the Zone 1
design pressure determined in accordance with FBC 1609. In this case, 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 WD1, FM Loss Prevention Data Sheet 1-29 and Roofing
Application Standard RAS 117. Assemblies marked with an asterisk* carry the limitations set forth in
