Polyflex 5.0 membranes are premium, polyester reinforced APP (plastomeric) modified bitumen roofing products specially designed for heat-welded applications. Constructed with a premium APP (plastomeric) compound, and incorporating superior non-woven polyester reinforcing, Polyflex 5.0 provides an exceptionally robust and durable roofing product which is easy to install and will provide long-term weathering performance that resists natural forces and other factors on the rooftop.
The top is constructed with a smooth sand surface while the bottom has a factory applied burn-off film.
Successive system layers can be heat welded with an additional ply of Polyflex 5.0 or Polyflex G cap sheets.
