5.6.1 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 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 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.
#1 Maximum Design Pressure = -52.5 psf:
Deck: Min. 15/32-inch plywood to meet project requirements to satisfaction of Authority Having
Jurisdiction.
Primer: None
Underlayment: Weather -Armor® FT3 Tile Underlayment or Eagle -Armor by Apoc, self -adhered.
#2 Maximum Design Pressure = -135.0 psf:
Deck: Min. 19/32-inch APA span -rated CDX plywood to meet project requirements to satisfaction of
Authority Having Jurisdiction.
Primer: None.
Underlayment: Weather -Armor® FT3 Tile Underlayment or Eagle -Armor by Apoc, self -adhered.
