Polyglass Announces New Code Approvals for Fire-Resistant Polystick XFR Underlayment

Polyglass U.S.A., Inc., announced that its self-adhered fire-resistant underlayment, Polystick XFR, has received a new Notice of Acceptance (NOA) from Miami-Dade County (NOA No.: 20-1117.03).

Polystick XFR is a dual-purpose fire-resistant and self-adhered waterproofing underlayment that offers superior fire resistance for a variety of high-temperature applications, including combustible decks with metal roof coverings.

The approved use of the product includes installation over an anchor sheet mechanically fastened to non-insulated wood decks. Please refer to the NOA for system specific limitations and installation requirements.

The Miami-Dade NOA represents the latest in a growing number of code approvals for Polystick XFR as industry regulatory agencies recognize its ability to meet or exceed their standards for superior roof protection.

As of now, Polystick XFR holds approval with the following Code Agencies:

  • Underwriter Laboratories (UL)
  • International Codes Council (ICC-ES)
  • Miami-Dade County
  • Florida Building Code (FBC)
  • Texas Department of Insurance (TDI)
  • California Office of State Fire Marshal (Cal OSFM)

Polystick XFR underlayment consists of an SBS (elastomeric) modified bitumen upper compound and an aggressive self-adhesive compound on the bottom featuring our patented ADESO® self-adhering technology. Polystick XFR also features our patent-pending Burn-Shield™ technology, which offers outstanding resistance to flame spread. The result is an advanced penetration-resistant, fire-resistant, easy-install underlayment that offers unmatched waterproof resistance while also being rated to withstand temperatures up to 265 °F.

These recent code approvals for Polystick XFR underscore Polyglass’ ongoing commitment to develop industry-leading technologies and solutions for commercial roofing systems across the globe.

Self-Adhered Fire-Resistant Roof Underlayment

Polyglass U.S.A., Inc., offers Polystick XFR, a dual-purpose fire-resistant and self-adhered waterproofing underlayment designed to provide superior fire resistance for combustible decks with metal roof coverings and other high-temperature applications.

According to the company, Polystick XFR combines ADESO and Burn-Shield technologies with the highest quality materials to yield a product that excels in providing robust fire protection and reliable waterproofing. 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 degrees Fahrenheit.

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.”
