Standard Black EPDM Membrane

RoofWrap Standard Black EPDM is a high performance non-reinforced rubber membrane that stands up to tearing, impacts, punctures and normal roof traffic. The elastomeric properties of the EPDM membrane compensate for thermal shock and building movement. EPDM membranes provide excellent resistance to ozone and aging. The membrane is manufactured in accordance with the guidelines established by the RMA (Rubber Manufacturers Association) and meets all government specifications as well as the ASTM Standard Specification D-4637.


Roll sizes for .045" Standard Black EPDM membranes are sold in widths of 11', 13', 15' and 17' (shorter and wider widths are special order) and custom cut to length to fit with sufficient perimeter overhang for attachment over the perimeter edge.

Basic Uses

Can be installed as a new elastomeric roofing membrane in Standard, Hybrid Attached and Fully Adhered roofing systems.

Code Approvals

The Standard EPDM membrane may be provided with UL and FM labels. Both UL and FM classified assemblies are available (FM 1-60 and 1-90, UL Class A, B and C).
