Step up your roofing game with Polyglass APP Membranes. Designed for the modern contractor, our APP sheets are perfect for low-slope roofs in areas with harsh climates. You have the flexibility to choose between a wide variety of heat-welded membranes, which offer efficient seam bonding, even self-adhering options that eliminate the need for torches or hot asphalt. Both types are reinforced for added strength and longevity.

What Are APP Membranes?

Polyglass manufactures roofing membranes with Atactic Polypropylene (APP) modified asphalt, featuring robust construction and crafted using high-quality APP (plastomeric) compounds for enduring weather resistance. They are strengthened with quality reinforcing mats of polyester and/or fiberglass to make them tougher, less likely to tear or become compromised over time. Think of Polyglass APP systems as extremely durable sheets that you can install on a roof to protect it from leaks, UV damage, and other environmental factors.

Contractors choose these membranes because they offer a reliable barrier from the outdoor elements. The modified asphalt in the APP formulation provides excellent water resistance and temperature variations. At the same time, the reinforcement mats add an extra layer of protection against punctures and tears that could compromise the membrane’s integrity.

When properly installed as part of a multi-ply roofing system, APP membranes create a watertight surface that effectively keeps moisture out, thereby protecting the building structure and its interior from the damaging effects of water. This makes them a go-to choice for commercial roofing projects of all designs, such as office buildings, warehouses, and retail centers, where long-lasting weather protection is a necessity.

APP membrane systems are also ideally suited for industrial settings that involve exposure to harsh environments or extreme temperatures, and for residential construction where other traditional roof coverings aren’t as effective.

Beyond roofs, Polyglass APP-modified bitumen roofing systems can be used in a variety of construction and landscaping projects for above and below-grade waterproofing on building types such as:

  • Hospitals
  • Schools
  • Hotels
  • Sporting Arenas, etc.

Why Choose Polyglass APP Membranes?

One of the key advantages Polyglass offers with every one of our product types is the ease of installation, and this holds true for our APP membranes as well. You get two options for applying these membranes: heat-welded and self-adhered.

Heat-welding membranes are ideal where use of a torch to soften the bitumen on the underside of the membrane, bonding it to the substrate. This is particularly useful for larger commercial projects where production type work is of the essence.

Conversely, our self-adhering APP membranes incorporate our patented ADESO® Technology. By simple removal of a split release film and applying firm and even pressure, will affix the membrane to the substrate, and using a roller to achieve complete contact and adhesion.

Polyglass APP self-adhesive membranes are designed with a specialized polymeric adhesive compound layer that bonds securely to the substrate upon application. This is ideal for both small and big projects or in situations where an open flame is not possible.

Both heat-fused and self-adhesive APP membranes include our granule-free end lap feature FASTLap®, which allows the ends of the membranes to overlap more cleanly, making it easier to create a watertight seal. It also speeds up the installation process because you are not fighting against uneven surfaces.

A specialized technology only available on Polyglass self-adhesive APP membranes is our SEALLap® ULTRA, which utilizes our aggressive self-adhesive compound at the side lap of the membrane. When the APP membranes overlap at the sides, this adhesive activates and creates an instant, incredible bond. It has been tested to be stronger than other even more traditional lap application methods, so you can have complete confidence in the durability of the roofing system you’re installing.
