Polyflex is an Atactic Polypropylene (APP) modified bitumen roofing membrane reinforced 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 smooth sand surface while the bottom has a factory applied burn-off film for heat welding applications.

Successive system layers can be heat welded with an additional ply of Polyflex or Polyflex G cap sheets. Polyflex is an approved mechanically attached base sheet for the Velociflex system.
