Abstract

In just the past few years, there has been industry-wide acceptance of the use of oneply roofing systems. This has basically involved three major groups: elastomerics, thermoplastics, and modified bitumens. The use of these different one-ply membranes over a variety of substrates has led to a virtual collage of roofing systems available on the market today.

The relative puncture resistance of these membranes, in conjunction with their substrates, has not been clearly understood. At present, several different methods of measuring static and dynamic puncture resistance are used by a variety of organizations, such as ASTM, the Canadian General Standards Board (CGSB), the European Union of Agrement (EUAtc), and various manufacturers.

This paper addresses some preliminary data relating to the dynamic and static puncture resistance of one-ply assemblies.
