Duro-Fleece® PVC Roofing Membrane

A fleece-backed roofing membrane for added puncture protection

The performance of Duro‑Last® in a fleece roll good

Duro-Fleece combines our proprietary Duro-Last PVC thermoplastic membrane with a high-quality fleece material on the underside of the membrane for added durability and puncture protection. Our proprietary Duro-Last PVC formulation provides exceptional flexibility, reflectivity and resistance to UV radiation, fire and a broad range of chemicals. Duro-Fleece membrane is compatible for direct installation over structural concrete or gypsum (poured in place or precast), aged built-up roof (BUR) and lightweight concrete (insulating or cellular). Once adhered or mechanically fastened, Duro-Fleece is smooth on the surface and aesthetically pleasing.

Industry leading performance —
Edge‑to‑Edge and Deck‑to‑Sky™

Duro-Last is a full system roofing provider — from the roof deck to insulation and membrane to custom-fabricated accessories, edge metal, drains, flashings, fasteners and adhesives — we have your roofing needs covered.

Membrane Features

  • PVC roll good with high-quality fleece backing provides superior protection against punctures.
  • Proprietary Duro-Last PVC formulation provides energy savings and fire resistance and is recyclable.
  • Membrane rolls have one 3-inch selvage edge, without fleece, to enable rooftop hot-air welding to the adjacent membrane roll, reducing welding and enabling a quick, quiet and easy installation.
  • Fleece-backed membrane can be adhered over a wide variety of roof substrates including structural concrete, aged built-up roof, gypsum and lightweight concrete. It can also be mechanically fastened over existing asphalt roofing systems.
  • A robust top performance layer (or “thickness over scrim”) of the PVC membrane exposed to weather, the environment, chemicals and human activity provides exceptional reflectivity, flame retardance, and UV and chemical resistance.
  • Weft-inserted (or “woven”) anti-wicking scrim roofing material with a density of 18 by 9 threads per inch provides superior strength and puncture resistance.
  • A complete line of Duro-Fleece custom-fabricated accessories is available, reducing labor and the potential for leaks at critical transition areas of the roof.
  • NSF/ANSI 347 Gold certified; UL and FM approved.
  • Backed by Duro-Last’s extensive range of best-in-class warranty options.
