EPDM Thermoset Single Ply Roofing Systems

Single ply membranes entered the U.S. low-slope roofing industry during the 1970s. There are two basic types: thermoplastic (plastic polymers) and thermoset (rubber polymers).

The material used by JM Roofing Systems for its thermoset single ply membrane is called EPDM (ethylene propylene diene monomer). The polymer allows the membrane to become quite rubber-like, deforming under stress and recovering its original shape when the stress is removed. This gives the membrane superior weatherability through a wide range of temperature fluctuations. The material also demonstrates superior ozone resistance and is quite resistant to ultraviolet rays, requiring no coatings.

UltraGard EPDM membranes are large, factory-fabricated sheets spliced together on-site with compatible adhesives or tapes, offering time-saving economic advantages and clean application. The EPDM sheets may be loose-laid and ballasted, mechanically attached with fasteners, or fully adhered. The complete product line includes adhesives, sealants, flashing materials, coatings and accessories to provide a single-source systems approach to the roofing assembly.

UltraGard EPDM single ply systems are adaptable to many sizes and shapes of roofs, new or existing. They are recommended for slopes not exceeding two inches per foot for ballasted, and not exceeding six inches per foot for adhered and mechanically attached. All three application methods are suitable for new construction, retrofit or complete tear-off.
