Abstract
The performance of many PVC roof membrane systems has been quite good. Numerous problems, however, have been reported with several of the early generation unreinforced (also referred to as "non-reinforced") PVC membranes. The Midwest Roofing Contractors Association (MRCA) in 1979 and 1982, Griffin in 1982, Wallace in 1983, and Rosenfield in 1984, reported shrinkage, embrittlement, "impact fractures" and other unidentified types of problems. The majority of these problem jobs utilized unreinforced membranes, although in some instances, there were reports of reinforced PVC membranes experiencing embrittlement and / or splitting problems.
