GenFlex EPDM products withstand the test of time.

GenFlex Roofing Systems features three single-ply EPDM membranes: GenFlex EPDM (Ethylene Propylene Diene Monomer) - an elastomeric membrane GenFlex AFR an EPDM membrane that is fire retardant, and GenFlex FRM - an EPDM membrane reinforced with tough polyester fabric. Both are designed for ultra high performance. GenFlex EPDM systems have a performance history of over 20 years and can be warranted for up to 20 years depending on the system design

EPDM comes 45 mil (1.1mm) or 60 mil (1.5mm ) thick and is available in rolls up to 50'(15.2m) wide by 250' (76.2m) long. It is ideal for either new roofs or for roofing over a variety of common roof deck types and insulation materials

Installation systems include ballasted, fully-adhered and a number of mechanically-attached alternatives. Components include roofing tapes, bonding adhesive, sealants, flashing and applicable rooftop accessories

This is a high-performance membrane, resistant to tears, impacts, punctures and normal roof traffic. Normal structural movement has limited effect on its integrity. This membrane provides excellent resistance to ozone and ultraviolet light exposure.
