Features & Benefits: Roofing Superstore SBS Fast Torch Plus 2mm Glass Roofing Underlay - Pallet of 23

  • High performance to suit a professional roofer
  • Isotropic, thermally bonded, and rot-proof non-woven spun bound polyester carrier providing excellent mechanical properties and durability
  • High elasticity to make it perfect for all structures subject to dimensional variations and wherever elasticity and resistance is required

When storing, the rolls must be kept upright and protected from the sun (temperatures ranging between 0 and 40 Degrees Celsius) and well away from electrical plants and heat sources. No measures are needed to prevent the build-up of static electricity.

  • 2. The surface should be coated with a bitumen primer.
  • 3. The rolls should be aligned, with lap joints of at least 8.5cm.
  • 4. The membrane should be applied with an appropriate propane gas torch.

Questions & Answers


Do you need to put a layer of primer under top coat of felt as well as under underlay?


You would not need to prim the underlay before adhering the cap sheet. This is a torch on felt so would be applied by heating the bitumen with a blow torch.
