Polystick XFR is a dual purpose fire resistant and self-adhered waterproofing underlayment. Utilizing ADESO® dual-compound self-adhered technology, Polystick XFR features a SBS (elastomeric) modified bitumen upper compound and an aggressive self-adhesive compound on the bottom. Polyglass’ patent pending Burn-Shield Technology™ provides superior fire resistance.
Polystick XFR features a slip-resistant film surface which can be exposed up to 180 days. With a temperature resistance of up to 265°F, Polystick XFR is ideally suited for high temperature roof covering systems such as steel and copper roofing, where fire resistance is required or desired.
Can be installed as part of a multi-ply underlayment system when used as a secondary layer above Polystick MTS PLUS or Polystick XFR.
