PRODUCT DESCRIPTION, EV, Duro-Tuff, Duro-Fleece, and Duro-Fleece Plus are reinforced single ply polyvinyl chloride (PVC) membranes designed to be used in adhered roofing systems or mechanically fastened roofing systems as described in this report. The membranes are provided in rolls of various lengths and widths. These roofing systems consist of the single-ply PVC roofing membrane, insulation where used, barrier board or slip sheet where used, flashing, mechanical s, and adhesives that are installed on a combustible or non-combustible roof deck. These roofing assemblies comply with the following properties when installed as described in this report. Fire Classification: Roofing assemblies covered under this report have been tested for fire classification Class, B or C in accordance with NSI/UL790 or (STM E108), as required by Section of 2018, 2015, 2012, and 2009 IBC and Section R902.1 of the 2018, 2015, 2012, and 2009 IRC. Wind Resistance: Roofing assemblies covered under this report have been tested for wind uplift resistance in accordance with FM 4474, and therefor qualify for use under Roofing membranes Section of the 2018, 2015, 2012, and 2009 IBC. Metal edge securement for all systems shall be designed in accordance with NSI/SPRI ES-1, complying with Section of the 2018, 2015, 2012, and 2009 IBC. For certifications of metal edge securement systems in accordance with NSI/SPRI ES-1, see UL Online Certifications Directory Roof-edge Systems, Metal, for Use with Low-slope Roofing Systems (TGJZ). The roofing assemblies shall be designed to resist the design wind load pressures for components and claddings in accordance with Section 1609 of the 2018, 2015, 2012, and 2009 IBC and Section R905.1 of the 2018, 2015, 2012, and 2009 IRC. Physical Properties: The roofing membranes covered under this Report have been tested for physical properties in accordance with STM D4434 and STM G155, and therefore qualify for use under Section and Section of the 2018, 2015, 2012, and 2009 IBC and Section R of the 2018, 2015, 2012, and 2009 IRC.

3 Impact Resistance: The single-ply roofing membranes covered under this Report have been tested for impact resistance in accordance with Resistance to Foot Traffic Test in Section 5.5 of FM 4470 and therefore qualify for use under Section of the 2018, 2015, 2012, and 2009 IBC. In addition, each of the membranes covered under this report have been tested in accordance with STM D3746 for impact resistance as it relates to puncture. 5.1 Membranes: PVC (40 60 mils), EV (50 60 mils), and Duro-Tuff (50 80 mils) are membranes having a proprietary thermoplastic formulation consisting of PVC resins, plasticizers, stabilizers, biocides, flame retardants and U.V. absorbents which incorporate a weft-insertion knitted scrim that is laminated between two layers of PVC film giving the membrane strength and durability Duro-Fleece (50 80 mils) and Duro-Fleece Plus (50 60 mils) are Duo-Last PVC membranes combining its proprietary thermoplastic formulation. These membranes are manufactured with a fleece bound to the underneath side of the membrane for enhanced adhesion characteristics. Duro-Fleece and Duro-Fleece Plus are bound with 3.8 ounce and 5.5-ounce fleece, respectively. 5.2 Insulation: Foam plastic insulation when used shall have a flame spread index of not more than 75 when tested at the maximum thickness intended for the use in accordance with NSI/UL 723 or STM E 84 to qualify for use under Section and Exception 3 of the 2018, 2015, 2012, and 2009 IBC. To qualify for use under Section of the 2018, 2015, 2012, and 2009 IBC, a thermal barrier is not required for foam plastic insulation that is part of a Class, B or C roof-covering assembly, provided the assembly with foam plastic insulation complies with FM 4450 or UL s: s used to mechanically fasten insulation and membranes to the roof deck shall be corrosion resistant. Refer to the assemblies in les 1-18 for the specific s to be used. 5.4 dhesive: The adhesive used for adhering PVC membranes to the insulation or roofing substrate shall be as noted in the ppendix of this Report. 5.5 Sealer: Hybrid lap seams utilize solvent-based contact bonding agent to adhere adjacent sections of PVC membranes. 5.6 sphalt: Hot roofing asphalt, when specified in the roofing assemblies shall conform to STM D312, Type III or Type IV.
