Specify UL 790 Class A fire rating for all applications of less
37、than 1:4 slope. Slope greater than 1:4 may require Class B rating based on flame spread on steeper slope.Factory Mutual (FM) 1-90 wind uplift is the minimum recommendation for all spray foam roofing applied directly to deck substrates. The wind rating of sprayed foam applied to an existing roof syst
38、em is typically the same as the rating of the existing roof system.*The complete roof system shall have a UL 1256, UL 790, Class A or B fire rating, be listed as “fire classified“ in UL Bld Mat Dir, and bear the UL label or be listed as a Class 1 Roof Deck in FM APP GUIDE. Roofing system over steel
39、deck shall be rated Class 1-90_ in accordance with FM APP GUIDE. Ratings from other independent laboratories may be substituted provided that the tests, requirements and ratings are documented to be equivalent, to the satisfaction of the Contracting Officer.1.2.2 Performance RequirementsThe installe
40、d roof system shall be watertight; free of defects including foam and coating delamination, blistering, or voids; suitable for the climatic and service conditions of the installation; and shall provide for positive drainage of the roof area.1.3 SUBMITTALS*NOTE: Review submittal description (SD) defi
41、nitions in Section 01 33 00 SUBMITTAL PROCEDURES and edit the following list to reflect only the submittals required for the project. Submittals should be kept to the minimum required for adequate quality control.A “G” following a submittal item indicates that the submittal requires Government appro
42、val. Some submittals are already marked with a “G”. Only delete an existing “G” if the submittal item is not complex and can be reviewed through the Contractors Quality Control system. Only add a “G” if the submittal is sufficiently important or complex in context of the project.For submittals requi
43、ring Government approval on Army projects, a code of up to three characters within the submittal tags may be used following the “G“ SECTION 07 57 13 Page 8Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-designation to indicate the approving authority
44、. Codes for Army projects using the Resident Management System (RMS) are: “AE“ for Architect-Engineer; “DO“ for District Office (Engineering Division or other organization in the District Office); “AO“ for Area Office; “RO“ for Resident Office; and “PO“ for Project Office. Codes following the “G“ typically are not used for Navy, Air Force, and NASA projects.Choose the first bracketed item for Navy, Air Force and NASA projects, or choose the second bracketed item for Army projects.*
