SBS-Modified Bitumen Roof Assemblies

Paradiene 20/30 is a proven, lightweight, two-ply, highly flexible membrane system designed to retain its elasticity through severe solar load, ultraviolet rays, thermal shocks, and extreme low temperature. Both top and base plies consist of an elastomeric asphalt blend - a unique formulation of SBS and high quality proprietary asphalt - reinforced with a fiberglass mat. The Paradiene 20 base ply absorbs roof stresses while the granule surfaced top ply, Paradiene 30, shields the base from the elements and mechanical abuse. The granule surface means the system doesn't require the application of gravel, giving it a light installed weight of approximately 200 pounds per square, and making inspection and repair easier.

Veral combines the proven waterproofing characteristics of SBS-modified asphalt and the stability and strength of glass mat/glass scrim with the protection and dramatic appearance of metal foil. The Veral System is composed of two sheet components - a smooth-surfaced base ply (Paradiene 20 or Irex) and Veral. The finish ply, Veral, combines a glass mat/glass scrim-reinforced SBS-modified bitumen base with a protective aluminum foil facing. Because metal and asphaltic materials expand at different rates, special features have been engineered into Veral's design. Using a patented embossing system, small control channels are built into the metal facing. A thin layer of low-melt asphalt is factory applied beneath these channels, allowing the metal to expand and contract independently of the modified bitumen base.
