Burn Shield® Technology

What is Burn-Shield Technology?

Burn-Shield Technology is a Patented innovation that offers fire resistance capable of achieving the highest level of fire ratings on steep-slope roofs, featured in Polystick XFR, a self-adhered high temp underlayment and Polyanchor XFR, a nailable underlayment.

POLYSTICK® XFR

Polystick® XFR is a dual-purpose fire resistant and self-adhered waterproofing underlayment, which feature Burn-Shield and ADESO® Technologies. The result is a product that helps in achieving superior waterproofing and UL Class A fire protection in a single layer*, instead of the typical solution requiring multiple layers to achieve the same result.

This translates to labor and material cost savings which ultimately benefits the building owner and contractor. The building occupants can enjoy the peace of mind knowing that Polystick XFR is providing safety and protection of their possessions while complying with fire-rated building codes required in many municipalities.
