Polyglass U.S.A. have launched Polystick XFR, a dual-purpose fire-resistant and self-adhering waterproofing underlay for metal roof coverings in high-temperature applications.
The product achieves UL Class A fire ratings for combustible decks while also providing long-term superior weathering performance.
Utilizing the company's ADESO Dual-Compound Self-Adhered Technology, 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° Farenheit.
Because Polystick XFR is specifically designed for high-temperature applications, the manufacturer describes it as the "ideal underlayment for metal roof covering systems like steel, copper and similar materials".
The product is also approved for use under asphalt shingles, mechanically attached tiles, and any other application where fire resistance is needed or desired.

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," says 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."
