SBS Heat Welded Membranes

Flexibility, strength, and dimensional stability for multi-ply low-slope roofing projects.

Polyglass’ SBS (Styrene-Butadiene-Styrene) modified bitumen membranes use a proprietary formulation consisting of the highest quality asphalt, polymers, and modifiers.

Our SBS membranes are reinforced with polyester and/or fiberglass mats offering superior flexibility, excellent tensile strength, and dimensional stability. The final product provides a highly durable roofing membrane that is capable of sustaining a variety of environmental conditions over time.

  • How is modified bitumen installed?

    Polyglass SBS and APP membranes are available in a variety of installation methods to best suit your application.

    SBS installation methods:

    • ADESO® Self-Adhered
    • Heat-Welded
    • Hot Mop
    • Mechanically Attached
    • Cold Applied

    APP installation methods:

    • ADESO® self-adhered
    • Heat-welded or torch applied
  • What is the difference between APP and SBS membranes?

    APP (Atactic Polypropylene) and SBS (Styrene-Butadiene-Styrene) refer to the type of substance that “modifies” the modified bitumen. In the case of an APP modified bitumen membrane, a durable plastic known as atactic polypropylene is added. In the case of SBS modified bitumen membranes, a synthetic rubber known as styrene-butadiene-styrene is added. In simple terms, you can think of APP modified bitumen as plastic asphalt and SBS modified bitumen as elastic asphalt.
