... A service life prediction approach for roofing membranes and systems is proposed based on a probabilistic modeling of the time-dependent performance. The membrane performance is modeled using a discrete Markov chain that evaluates the change of performance over time as a result of deterioration...

... As part of a five-year investigation, mechanical (strength and elongation) and chemical (thermogravimetry and dynamic mechanical analysis) methods of evaluation are used in this paper to characterize in-service thermoplastic olefin (TPO) roof membranes. All the non-reinforced membranes meet...

... Roofing membranes are subjected to a tear stress when stretched near a notch, cut, or nail hole. The force required to initiate or propagate tears in roofing membranes was studied using various standard test methods. The materials used in the study included reinforced EPDM (ethylene propylene...

... The past twenty years is considered to be a landmark and revolutionary advancement period for the progress and recognition of various classes of Single-Ply Roofing Membranes in Canada and the United States. During the same two decades, parallel and independently tremendous efforts and billions...
