TRINITY ERD <br /> 4. PRODUCT DESCRIPTION: <br /> This Evaluation Report covers Duro-Last Single Ply Roof Systems installed in accc�rdance with Duro-Last <br /> published installation instructions and the Limitations/ Conditions of Use herein. <br /> ➢ Duro-Last roof cover is a nominal 40-mil (1.0 mm), 50-mil (1.3 mm) or 50-mif (1.5-mm) thick <br /> thermoplastic (PVC) roof covering having an 18 x 14 polyester fabric reinforcement composed of 840 <br /> x 1000 denier threads. <br /> ➢ Duro-Tuff roof cover is a nominal 50-mil (1.3 mm) or 60-mil (1.5-mm) thick thermoplastic (PVC) <br /> roof covering having an 18 x 9 polyester fabric reinforcement composed ��f 840 x 1000 denier <br /> threads. <br /> ➢ Duro-Fleece Plus are a nominal 50-mil (1.3 mm) or 60-mil (1.5-mm) thick thermoplastic (PVC) roof <br /> covering having an 18 x 14 polyester fabric reinforcement composed of 840 :K 1000 denier threads <br /> and a polyester fleece backing. <br /> S. LIMITATIONS: <br /> 5.1 This Evaluation Report is not for use in HVHZ. <br /> 5.2 Refer to a current Roofing Materials Directory for fire ratings of this produd. <br /> 5.3 For steel deck installations, foam plastic insulation shall be separated from the building interior <br /> in accordance with FBC 2603.4 unless the exceptions stated in FBC 2603.4.1 or 2603.6 apply. <br /> 5.4 Unless otherwise noted in Appendix 1, roof decking and its attachment :shall be specified and <br /> installed to meet project design criteria to the satisfaction of the AHJ. <br /> 5.5 For recover installations, the existing roof shall be examined in accordance with FBC 1510. <br /> 5.6 For mechanically attached insulation or membrane or strip-bonded insulation, the maximum <br /> design pressure for the selected assembly shall meet or exceed the Zone 1 design pressure <br /> determined in accordance with F8C Chapter 16. Zones 2 and 3 shall employ an attachment <br /> density designed by a qualified design professional to resist the elevated pressure criteria. <br /> Commonly used methods are RAS 117, RAS 137, FM LPDS 1-29 and ANSI/SPRI WDi. <br /> Assemblies marked with an asterisk* carry the limitations set forth in Section 2.2.1.5.1(a) of <br /> FM LPDS 1-29 for Zone 2/3 enhancements. <br /> 5.7 For assemblies with all components fully bonded in place, the maximum design pressure for the <br /> selected assembly shall meet or exceed critical design pressure determined in accordance with <br /> FBC Chapter 16. No rational analysis is permitted for these systems. <br /> 5.8 For mechanically attached insulation or membrane over existing roof decks, fasteners shall be <br /> tested in the existing deck for withdrawal resistance. A qualified design professional shall <br /> review the data for comparison to the minimum requirements for the system. Testing and <br /> analysis shall be in accordance with TAS 105 or ANSI/SPRI FX-1. <br /> 5.9 For bonded insulation or membrane over existing substrates in a re-roof (tear of� or recover <br /> installation, the existing deck or existing roof surtace shall be examined for compatibility with <br /> the adhesive to be installed. If any surface conditions exist that bring system performance into <br /> question, field uplift testing in accordance with ASTM E907, FM LPDS 1-52, ANSI/SPRI IA-1 or <br /> TAS 124 shall be conduded on mock-ups of the proposed new roof assembly. <br /> 5.10 For bonded insulation or membrane over existing substrates in a recover installation, the <br /> existing roof system shall be capable of resisting project design pressures on its own merit to <br /> the satisfaction of the AHJ, as documented through field uplift testing in accordance with ASTM <br /> E907, FM LPDS 1-52 or TAS 124. <br /> Exterior Research and Design, LLC. <br /> Certlficate o/Authorization aor95o3 Evaluation Report D9750.05.08-R5 <br /> FL1559-R8 <br /> Revision 5: 02/15/2013 <br /> Page 3 of 4 <br />
