...David Straup Slick; Nicholas A. Piteo; Dean A. Rutila Foamed adhesives are used to join roofing assembly components to the roof substrate and to each other. A variety of performance problems with foamed adhesives as installed in roofing assemblies have led to assembly failures. We previously...

...Mindy Costello This standard development began with a partnership between members of the roofing industry and NSF International to facilitate the thorough communication of information that is verifiable and accurate about the environmental and social impacts associated with the production and use...

...David Straup Slick; Nicholas A. Piteo; Dean A. Rutila In low sloped roofing systems, poorly adhered roofing assemblies are unable to resist significant wind loads and are likely to be further damaged or destroyed by wind events well below the design wind pressures for the assembly. The design...

...A. Baskaran; J. Wu; H. Tanaka Adhesive Applied Roofing System (AARS)s are regaining popularity in the Canadian low slope application. AARSs use no fasteners. All components (e.g., steel deck, vapour barrier (if any), insulation board, cover board, base sheet, and cap sheet) are integrated using...

...Edward S. Lindow; Mark L. Michener Paraphrasing an old adage, anything worth doing, will be hard to accomplish. And so it is with retrofitting an existing building with a “green roof.” This paper presents a case history of funding, designing, and installing a vegetated green roof on the existing...

...Gaylon L. Baumgardner; Geoffrey M. Rowe Asphalt specifications in the U.S., Europe, and elsewhere in the world are increasingly dependent upon basic principles of rheology, in particular dynamic shear rheology (DSR). The roofing industry would be benefited by a revised ASTM specification featuring...

...Stanley Graveline The use of thermoplastic roofing membranes has grown dramatically over the past years. This has occurred for a number of reasons including the proven track record of some products, the move to light colored “cool” materials, and the variety of systems available. A key benefit...
