Polyglass Creates Self-Adhered, Fire-Resistant Roof Underlayment

Roofing and waterproofing system manufacturer Polyglass USA has developed Polystick XLR, a new double roof underlay that provides water and fire resistance in high temperature applications, including combustible decks with metal roofs.

The self-adhesive membrane combines the existing ADESO and Burn-Shield technologies from Polyglass into a product that, according to the manufacturer, is outstanding in both protection areas. It has an SBS (elastometrically) modified bitumen upper mass and a self-adhesive lower mass with glass fiber reinforcement for additional stability. It has a UL Class A fire protection rating for flammable deck applications and can withstand temperatures of up to 265 degrees Fahrenheit.

“I’m very happy about Polystick XFR,” says Marco Sieber, national product manager for Polyglass, “because in a market with very few others, Polyglass can offer an extremely high-performance product from the point of view of fire, water protection and labor savings.” good options for the contractor, planner and builder. “

The Polystick XFR can be used as a secondary layer over the Polystick MTS Plus from Polyglass and can be exposed to the elements for up to 180 days. Polyglass.us
