A Proven Alternative to Traditional Roofing Build-ups

Insulated roof deck systems offer a proven alternative to traditional, multi-layer, low slope roofing systems. This revolutionary approach to roofing construction provides a complete roof in only two components to simplify the design, procurement and installation of a low slope roof system by eliminating traditional, individual components such as a steel deck, vapor barrier, multiple layers of board insulation, and cover boards.
