Abstract
Four test roofs were installed across the Western U.S. by the WSRCA in 2001 as part of its TPO weathering farm project. An overview of the findings gleaned from the field, as the membranes now progress into their fifth year of weathering, will be presented. This will include field observations and field solar reflectivity testing data. In addition, laboratory results such as: breaking strength, elongation, thickness, glass transition temperature, thermopgravimetry, and spectroscopy will be presented. Over, this presentation is intended to provide roof consultants, roofing contractors, manufacturers, roof designers, and specifiers with updated technical information regarding TPO roof membranes. Attendees are expected to depart with an understanding of the WSRCA TPO weathering farm project, TPO roof membranes in general, the problems with some of the earlier formulations, the successes regarding reflectivity, and other current pertinent information.
