An Evaluation of Polyvinyl Chloride (PVC) Single-Ply Membrane Roofing Systems.

Abstract

This report documents a study to evaluate PVC single-ply membrane roofing systems and materials for use at Army installations. It was found that PVC single-ply membranes can be used as an alternative to conventional built-up roofing (BUR) for new roofs or to reroof failed roofs. However, because PVC systems are relatively new and long-term durability statistics are not available, they should only be used on carefully selected Army roofs. The two most serious PVC membrane problems identified during the study were: Embrittlement caused by plasticizer loss or by exposure to ultraviolet rays, and Excessive shrinkage. It was concluded that these problems can be minimized by using reinforced PVC membranes and by using manufacturer-improved ultraviolet- and evaporation-resistant membranes.
