Introducing Polystick XFR, a dual-purpose fire resistant and self-adhered waterproofing underlayment featuring Burn-Shield Technology


Polyglass U.S.A., Inc., a leading manufacturer of roofing and waterproofing systems, is pleased to announce the release of Polystick XFR, an advanced dual-purpose fire-resistant and self-adhered waterproofing underlayment that provides superior fire resistance for combustible decks with metal roof coverings and other high-temperature applications.

Where other fire-rated underlayment products struggle to strike a balance between robust fire protection and reliable waterproofing, Polystick XFR successfully combines our ADESO® and Burn-ShieldTM technologies with the highest quality materials to yield a product that excels in both areas. This product achieves UL Class A fire ratings for combustible decks while also providing long-term superior weathering performance.

Utilizing ADESO Dual-Compound Self-Adhered Technology for fast, labor-saving application, Polystick XFR features an SBS (elastomeric) modified bitumen upper compound and an aggressive self-adhesive compound on the bottom. Fiberglass reinforcement provides additional strength and stability, and Polyglass’ own patent-pending Burn-Shield Technology provides superior resistance to flame spread. The end result is a penetration-resistant underlayment of unmatched quality rated to withstand temperatures up to 265 °F.

Because Polystick XFR is specifically designed for high-temperature applications, it is an ideal underlayment for metal roof covering systems like steel, copper and similar materials. It is also approved for use under asphalt shingles, mechanically attached tiles, and any other application where fire resistance is needed or desired. When used as a secondary layer above Polystick MTS PLUS, this product can be installed as part of a multi-ply underlayment system. And because Polystick XFR can be exposed for up to 180 days, contractors can use it with confidence on works-in-progress.

“I’m excited about Polystick XFR,” said Polyglass National Product Manager Marco Sieber, “because Polyglass is able to offer an extremely high-performance product from a fire plus water protection and labor savings perspective in a market with very few other good options for the contractor, specifier and building owner.”

Polyglass U.S.A., Inc., is available to answer any questions about this exciting new product. For specification sheets and more information about Polystick XFR and our other roofing and waterproofing products, please visit polyglass.us.
