Polyflex is an Atactic Polypropylene (APP) modified bitumen roofing membrane with a superior non-woven polyester mat that provides flexibility and dimensional stability as well as excellent tear and puncture resistance. The premium APP compound and durable construction provides long-term weathering performance. Polyflex is designed for use as base, interply, or cap sheet in multilayer low-slope assemblies.
The top is constructed with a factory-applied “wet talc” surface while the bottom has a burn-off film.
Successive system layers can be heat welded with an additional ply of Polyflex or Polyflex G cap sheets.
