30、brane and paver ballasted system configurations, the preferred norm is to attach the PVC membrane roof over a minimum, two layer assembly of rigid board roof insulation (this norm does not apply to IRMA or garden-style roofs). Additionally, adhered and mechanically fastened PVC membrane roofing syst

31、ems must utilize reinforced membrane, always. Exception to use of reinforced PVC membrane is given only for specialized, pre-fabricated PVC roof system detail flashings (not deck sheet) that are supplied, warranted and recommended in the printed instructions published by the specified PVC membrane r

32、oof system manufacturer.Stone and/or gravel ballast will not be utilized on any PVC membrane roofing system.Adhered and mechanically fastened systems are preferred along flight lines, in wind zones exceeding 160 km/h (100 mph), within 8 km (5 miles) of coastline, within 457 m (1500 feet) of an open

33、body of water, and on or adjacent to critical facilities such as hospitals; but a combination adhered/protected membrane system utilizing paver ballast can be specified using interlocking pavers designed to both protect the underlying PVC membrane from airborne projectiles and to help provide the re

34、quired wind load resistance established by local building code and designer preference.Combination adhered/protected roof membrane attachment should only be specified for isolated geographic locations that experience extreme and extended wind conditions such as portions of Alaska, Iceland, Florida a

35、nd the Gulf coast, or as otherwise required by the Government. Other mechanically fastened or adhered PVC membrane roof system installation configurations are also accommodative to such excessive wind loading conditions.Where an air barrier is required, it should be applied at the deck level or with

36、in the insulation sandwich. Air barriers are specified in Section 07 22 00 ROOF AND DECK INSULATION.SECTION 07 54 19 Page 6Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Where one membrane system configuration is required for all roof areas, use the

37、 first paragraph. Where different system configurations are required, use the second paragraph successively and replace the open brackets with a description of the substrate(s) or area of the building or project where each system is to be applied.*Adhered Mechanically fastened Combination adhered po

Incorporate air barrier in the roof assembly as specified in Section 07 22 00 ROOF AND DECK INSULATION.1.3 ASSEMBLY REQUIREMENTS*NOTE: For guida

39、nce on flashings and drainage details, the designer should consult the SMACNA “Architectural Sheet Metal Manual.“*Roofing membrane sheet widths shall be consistent with membrane attachment methods and wind uplift requirements, and shall be as large as practical. In order to minimize joints and 3-way

40、 overlaps, prefabricated sheets are not accepted. Provide membrane which is free of defects and foreign material. Coordinate flashing work to permit continuous roof-surfacing operations. Insulation shall be applied and weatherproofed on the same day.1.3.1 Fire ResistanceComplete roof system assembly

41、:*NOTE: Specify Class B option only when Class A may not be attainable such as membrane system application directly to wood deck. Provide justification/rationale for Class B option with design submission*a. Class A or B rated in accordance with ASTM E108, FM 4470, or UL 790; andb. Be listed as Class

42、 I roof deck construction in FM APP GUIDE.FM or UL approved components of the roof covering assembly shall bear the appropriate FM or UL label.1.3.2 Wind Uplift Resistance*NOTE: Determine the required wind uplift resistance based on ASCE 7 wind loading calculations or applicable building code requir

43、ements.The specified FM rating incorporates a safety factor SECTION 07 54 19 Page 7Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-of 2 over the maximum calculated uplift pressure. Therefore, a FM rating of 1-90 correlates to a maximum uplift calcula

44、tion of 2.2 kPa (45 psf). When a rated system is specified, ensure the specified roof system is capable of meeting the wind uplift resistance specified. Where non-rated systems may be permissible, include the bracketed option.Delineate calculated values in the roof specification or drawings. Utilize independently tested and rated roof systems, such as Factory Mutual (FM), Underwriters Laborator
