Underlayment

         Polyglass® U.S.A., Inc., a manufacturer of roofing and waterproofing systems, has announced 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 Polyglass’ ADESO® and Burn-Shield™ 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.  Also, because Polystick XFR can be exposed for up to 180 days, contractors can use it with confidence on in-progress projects.
