Introducing the ember-resistant, fire-rated underlayment

By Dani Sheehan. 

Polyglass leads the industry with their self-adhered roofing underlayment products to meet every steep-slope roofing situation and challenge. 

A well-protected steep-slope roofing system depends on its underlayment. With the right, easy-to-install products, underlayment provides an additional layer of protection between the elements and the building’s interior. Polyglass has positioned itself at the forefront of underlayment technology with its advanced ADESO® self-adhered roofing products. Their Polystick line of underlayments ensures that customers get the most advanced and trusted technology available, while also providing contractors with a cost-effective and safe installation process. They offer benefits like 30-year warranties and watertight protection, ensuring peace of mind for contractors and property owners. 

With a dual-purpose ember- and water-resistant design, the Polyanchor® XFR uses a plastomeric modified bitumen upper compound, coupled with a self-sealing SBS modified compound on the bottom, to offer superior protection, particularly in areas prone to wildfires. According to the Insurance Institute for Business and Home Safety, up to 90% of homes are indirectly destroyed by wind-borne embers. Featuring Polyglass’ patent-pending Burn-Shield Technology® for superior ember resistance, Polyanchor XFR is particularly suited under clay or concrete tile roofs.  

Key applications for the Polyanchor XFR underlayment include: 

• Full roof coverage: Polyanchor XFR protects combustible decks under Class A roof coverings from embers. 
• Water-resistant barrier: This underlayment can be used on steep-slope roofs under shingles, shakes and tiles to provide a water-resistant barrier. 
• Wildfire-prone areas: This product meets California code requirements for wildfire zones with its Class A fire rating. 

Other features include: 

• Compliance with California’s Wildland Urban Interface (WUI) code requirements 
• Fiberglass mat for improved strength and fire resistance 
• Mineral aggregate surface for slip resistance 
• Durable plastomeric modified asphalt top compound 
• Self-sealing elastomeric modified asphalt bottom compound
