The presentation will open with the history of EPDM membranes as well as their features and benefits. The use of EPDM membranes in new, re-roofing and recover applications in both conventional and protected membrane assemblies will be discussed. The demonstration will include the installation of the vapour retarder and the roof insulation, and a discussion of the attachment methods. The EPDM membrane will then be installed showing the positioning of the sheets, treatment of the edges and corners, and attachment and seaming techniques.
