This Underlayment is Optimal at Being Fire-Resistant and at Waterproofing

By Polyglass.  

Polystick XFR self-adhered fire-resistant roof underlayment is ideal for metal roof covering systems. 

Polyglass has announced the release of Polystick XFR, a self-adhered waterproofing underlayment that strikes the balance between fire resistance and waterproofing. Polystick XFR is designed for combustible decks with metal covering and high-temperature applications. Polystick XFR gives you the best of ADESO® and Burn-Shield™ technologies, to give you a product that surpasses expectations. The UL Class A fire ratings for combustible decks provides enduring 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.”
