HOT BITUMEN COMPATIBLE EPDM ROOFING SHEET

摘要

A roof membrane and a roof system employing an EPDM membrane (11) which is compatible with a bituminous adhesive. The membrane includes an outer layer (12) of polymeric layer such as EPDM bonded to a polyester protective layer (16) which is in turn bonded to a fleecy material (22). This can be adhered to a roof deck surface (24) using hot asphalt or bitumen (26) which bonds the fleecy material to the roof deck in turn holding the EPDM in place. The polyester layer (16) prevents the asphaltic material (26) from attacking and dissolving the EPDM with the fleecy material (22) providing good adhesion between the polyester and the EPDM.
