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-resistant 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, which powers Polystick® XFR and Polyanchor® XFR: two CAL FIRE BML-listed underlayments that contribute to meeting or exceeding 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 superior fire and ember resistance, ideally suited for high temperature roof covering systems such as steel, aluminum, or copper panels.
- Polyanchor® XFR – Dual-purpose, ember- and water-resistant mechanically attached underlayment ideal for use under clay/concrete tile roof covering systems.
CAL FIRE BML Listing: 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-resistant 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 CAL FIRE BML listing offer enhanced fire resistance, increased building protection, and long-term durability – essential features for wildfire-resilient design and post-disaster rebuilding efforts.
Insurance & Compliance Benefits
Installing a Polyglass fire-resistant 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.
