Modified Bitumen Membranes: Low-slope commercial APP and SBS roofing membranes
From the very beginning, Polyglass has led the industry in the development of high-quality modified bitumen roofing. That legacy continues today as we offer a large selection of modified bitumen roofing products and accessories designed to accommodate a wide range of commercial and residential roofing applications.
Our APP and SBS membranes not only afford outstanding protection, durability, and roof life expectancy, but are also environmentally friendly, energy-efficient, non-abrasive, UV-resistant, and visually pleasing.
Polyglass APP and SBS Membranes
Polyglass offers two main types of modified bitumen membranes — atactic polypropylene (APP) and styrene-butadiene-styrene (SBS).
APP Membranes
Polyglass provides a broad range of base, interply, and cap APP modified bitumen roofing membranes constructed with premium Atactic Polypropylene resins. Superior polyester and/or fiberglass reinforcing are incorporated to offer exceptional tensile strength, puncture resistance, and flexibility.
These membranes are bottom surfaced with polyethylene burn-off film, to provide our contractors with a product that satisfies specified roofing assemblies employing heat welding, torch, or self-adhered applications. Cap sheets have a granulated top surface which enhances the membranes’ UV resistance.
SBS Membranes
Polyglass uses a proprietary formulation for our SBS compound, and the highest quality asphalt, polymers, and modifiers.
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, able to sustain a variety of environmental conditions over time.
What is ADESO?
ADESO is a revolutionary self-adhered technology offered by Polyglass on many of our APP and SBS membranes. Using a combination of patented features, ADESO technology enables the manufacture of dual-compound membranes with a true APP or SBS formulation on the top weathering side and a powerful self-adhered formulation on the bottom layer, providing superior adhesion without the need for additional adhesives.
Roof Underlayment: Easy-to-install underlayment products for steep-slope roofs.
The key to a reliable, well-protected steep-slope roofing system is its underlayment. At Polyglass, we lead the industry with our selection of self-adhered roofing underlayment products to meet every steep-slope roofing situation and challenge.
Equipped with revolutionary ADESO® self-adhered technology, Polystick roof underlayments not only provide your customers with the most advanced and time-tested roofing technology on the market — they also save contractors time and money on installation cost.
