Modifleece is a fleece-backed Styrene-Butadiene-Styrene (SBS) modified bitumen roofing membrane base sheet for use in multi-ply low-slope roofing systems. Utilizing a unique laminating process, a specially formulated dual compound is integrated into the polyester fabric to create a monolithic bond between the two components. The self-adhered side laps are protected with a release film, which is removed at the time of application, exposing the aggressive self-adhered SBS compound, which provides immediate watertight seams.

Modifleece is applied using Polyglass LRF CR low rise foam adhesive in a spatter pattern while the top film surface offers application of a variety of Polyglass self-adhered or torched membranes.

  Extend the life of existing roof systems and avoid costly tear-offs – increase warranty coverage
 Use as a base ply adhered to LWIC (Lightweight Insulated Concrete) or to existing APP/SBS mod bit roofing system
 Fiberglass reinforced for added strength and dimensional stability
  Versatile: over semi-rough/irregular substrates; under torch or self-adhered APP/SBS cap sheets
