Mechanically Attached
Polybase V is an Atactic Polypropylene (APP) modified bitumen roofing membrane base sheet, reinforced with a fiberglass mat. The proprietary APP compound offers quality waterproofing and weathering physical properties. Polybase V is designed for use as a base ply or interply layer in multi-layer low-slope assemblies.
The top and bottom surfaces of Polybase V are finished with polyolefin film. Application methods include mechanically attached or heat-welded. Successive system layers can be heat welded with a ply of Polyflex or Polyflex G cap sheets.
