Deerfield Beach, FL – As California faces intensifying wildfire seasons and increasingly stringent building codes, Polyglass USA announces a major milestone in fire protection innovation.
Coupled with the recent patent of the company’s Burn Shield® Technology for steep slope underlayments, Polyglass is now the first manufacturer to receive CAL FIRE Building Materials Listing (BML) approval for a complete low-slope, Class A fire-rated modified bitumen roofing system – a first for the industry. This achievement reinforces Polyglass’ leadership in delivering high-performance, fire-resistant solutions across residential and commercial roofing.
Proven Innovation: Patented Burn Shield® Technology
Central to Polyglass’ fire defense portfolio is its proprietary, recently patented Burn Shield® Technology. Engineered to slow the spread of fire, this breakthrough innovation provides critical extra time for building occupants and first responders – especially important in California’s high-risk Wildland-Urban Interface (WUI) zones.
This technology powers Polystick® XFR and Polyanchor® XFR: two Class A, CAL FIRE BML-listed underlayments that meet or exceed California’s WUI code requirements for steep-slope roofing.
“For communities living and working in wildfire-prone areas, every second counts,” said Jimmy Akins, VP of Technical Services, Warranty & Support at Polyglass. “Our innovative Burn Shield® Technology isn’t just about compliance – it’s about safeguarding our customers, their families and their most prized possessions, when it matters most.”
Residential – Steep-Slope Underlayment Applications
- Polystick® XFR – Self-adhered waterproofing underlayment providing Class A fire ratings, ideally suited for high temperature roof covering systems such as steel, aluminum, or copper panels.
- Polyanchor® XFR – Dual-purpose, Class A fire rated ember- and water-resistant mechanically attached underlayment meeting California WUI code requirements.
CAL FIRE BML Approval: A Milestone for Low-Slope Roofing
The CAL FIRE Building Materials Listing confirms that Polyglass roofing systems meet the state’s rigorous fire performance standards, as tested under ASTM E108 and UL 790. This designation is crucial for compliance with the California Building Code Chapter 7A and helps streamline project approvals by local fire marshals and building inspectors.
Commercial – Low-Slope System
Polyglass is proud to be the first manufacturer to have a complete Class A fire-rated low-slope system included in the CAL FIRE Building Materials Listing. This milestone reinforces the company’s commitment to innovation, advancement in fire safety, and further strengthening its position in the industry. Details of the Polyglass system include:
- Deck: Minimum C-15/32
- Incline: 2:12
- Optional Insulation: Polyisocyanurate, perlite, or wood fiberboard
- Base Sheet: Elastobase V (mechanically fastened) or Elastoflex SA V FR / SA V Plus FR (self-adhered)
- Ply Sheet (Optional): Elastoflex SA V Plus FR / SA V FR
- Membrane: Elastoflex SA P FR or Polyflex® SA P FR (self-adhered)
The products in this BML-listing offer enhanced fire resistance, increased building protection, and long-term durability – essential features for wildfire-resilient design and post-disaster rebuilding efforts.

Installing a Polyglass Class A fire-rated system may help qualify property owners for insurance discounts under California’s “Safer from Wildfires” program. These systems also support home hardening measures identified by the California FAIR Plan, the state’s last-resort insurance option for high-risk homeowners who’ve been denied coverage by traditional carriers.
