substrates. The adhesives have a coverage <br />^ <br />rate of <br />approximately 100 square feet per gallon (2.5 m'iL). The <br />adhesives are supplied in 1s-gallon (56.7 L) and so{allon <br />(189 L) drums, box sets. and cartridge tubes and cylinders, <br />and have a shelf life of one year. <br />3.10.11 OlyBond 500 Adh€siver OlyBond 500 Spot Shot <br />and OlyBond 500 BA are two-component polyurethane <br />adhesives used to adhere insulations to various <br />substrates. The adhesrves have a coverage <br />" <br />rale of <br />approximately 100 square feet per gallon (2.5 m'lL). The <br />adhesives are supplied in cartridge tubes and box sets, <br />and have a shelf life of one year. <br />3.'l l lmpact Resistanco: <br />The EPDM, PVC, and TPO rooflng membranes described <br />in this report meet requirements for impact resistance in <br />IBC Section 1504.7, based on testing in accordance with <br />FM 4470. <br />4.0 INSTALLATION <br />4.1 Gonoral: <br />Installation of the EPDM, PVC, and TPO roofing <br />membranes described in this report must comply with the <br />applicable code, the manufacturer's published installation <br />instructions and this report. The manufacturer's published <br />installation instructions must be available at all times on <br />the jobsite during lnstallation. <br />The substrate to which the membrane is to be applied <br />must be clean, dry, and fr€e of frost, loose fasteners, and <br />other protrusions or contaminates that will interfere with the <br />adhesion or atlachment of the membrane or that will <br />puncture the membrane. All materials must be protected <br />against contact with incompatible materials. Where <br />gypsum board is used as barrier board in the roofing <br />assembly, weather protection must be provided to prevent <br />damage to the gypsum board prior to application of the <br />roofing membrane. <br />The slope of the roof on which the single.ply membranes <br />are installed must not be more than the maximum slope <br />indlcated for the particular assembly as listed in Tables 2 <br />and 3. <br />Penetrations and terminations of the roof covering must <br />be flashed and made weather tight in accordance with the <br />requirements of the membrane manufacturer and the <br />applicable code. <br />4.2 Firo Classification: <br />4.2.1 New Constructlon: The adhered and mechanically <br />fastened EPDM. PVC. and TPO single-ply membrane <br />roofing systems, when installed in accordance with this <br />report. are Class A, B or C roof covering systems in <br />accordance with ASTM E108 or UL 790, as noted in <br />Tables 2 and 3. <br />4.2.2 Rerooting: The existing deck must be inspected to <br />verify that the structure to be reroofed is structurally sound <br />and adequate to support and secure the roofing <br />membrane. Prior to installation of new roof clverings, <br />inspeclion by and written approval from the code official <br />having jurisdiction must be required. <br />Class A, B or C roof covering systems may be installed <br />over existing classified roof covering systems under the <br />following conditions without additional roof classification <br />tests. provided the resulting classitication is the lower of <br />the new or existing rooflng classification: <br />r New uninsulated systems installed only over existing <br />uninsulated assemblies. <br />I New insulated systems installed over existrng <br />uninsulated systems only. <br />4.3 Wind R€sistance: <br />4.3.1 New Construction: The allowable wind uplift <br />pressures for the EPDM, PVC, and TPO rooflng <br />membranes as parts of rool assemblies are noted in <br />Tables 4 and 5. <br />Metal edge securement for roofing systems must be <br />designed in accordance with ANSUSPRI ES-1, complying <br />with IBC Section 1504.5. The edge securement for <br />mechanically attached membranes was tested ln <br />accordance with ANSVSPRI ES-1 Test RE-1, using <br />Carlisle SecurEdge 300 [0.050-inch (1.27 mm) 3003 <br />aluminuml and Carlisle SecurEdge 3000 [0.040-inch <br />(1.02 mm) 3003 aluminuml fascia systems. The maximum <br />allowable load for Carlisle SecurEdge 300 is 234 plf <br />(348 kg/m). The maximum allowable load for Carlisle <br />SecurEdge 3000 is 200 p[ (298 kg/m). <br />4.3.2 Roroofing: Mechanically anchored systems may <br />be accepted based on the adequacy of anchors <br />penetrating through existing roof coverings into structural <br />substrates. Since the composition and/or condition of any <br />particular existing underlying material may vary widely, <br />reroofing with adhered systems is outside the scope of this <br />report. <br />5.0 coNorTtoNs oF usE <br />The single-ply EPDM, PVC, and TPO roofing membranes <br />described in this report comply with, or a.e suitable <br />alternatives to what is specified in, those codes listed in <br />Section 1.0 of this report. subject to the following <br />conditions: <br />5.1 lnstallation must comply with the applicable code, the <br />manufacturer's published installation inst.uctions and <br />this report. The instructions within this report must <br />govern iI there are any conflicts between the <br />manufacturer's installation instructions and this report. <br />5.2 The adhered and mechanically fastened single-ply <br />membrane roofing systems must be installed by <br />professional roofing contraclors who are trained and <br />approved by the manufacturer. <br />5.3 Foam plastic insulation must be separated from the <br />interio. of the building by an approved thermal barrier <br />in accordance with IBC Section 2603.4.1.5 or IRC <br />Section R314.4, as applicable. <br />5.4 Foam plastic insulation, where used. must bear the <br />label of an approved agency indicating that the foam <br />plastic has a flame-spread index of not more than 75 <br />when tested at the maximum thickness intended for <br />use in accordance with ASTM E84, subject to the <br />approval of the code official. <br />5.5 Design wind uplift pressure on any roof area, <br />including edge and corner zones, must not exceed <br />the allowable wind uplift pressure for the system <br />installed in that particular area. Refer to allowable <br />wind uplift pressures for systems as listed in Table 4. <br />5.6 The allowable wind uplift pressures listed in Table 4 <br />are for the roof covering system only. The deck and <br />framing to which the system is attached must be <br />designed for the applicable components and cladding <br />wind loads in accordance with the applicable code. <br />5.7 When application is over existing roofs, <br />documentation of the wind-uplift resistance of the <br />composite roof construclion must be submitted to the <br />code oflicial for approval at the time of permit <br />application. <br />ESR-1463 I Most lMdely Accepted and Trusted Page 4 of l0
