Roofing Outlaw 4kg SBS Modified Bitumen Torch-On Felt is built for serious roofing work. It’s manufactured using a heavy-duty non-woven polyester carrier, saturated and coated in SBS elastomer-modified bitumen. That combination gives you the flexibility to handle movement, the strength to resist tearing, and the durability to deal with British weather year-round.

Manufactured through a high-tech calendaring process, the membrane delivers consistent thickness, reinforcement and performance across the roll.
