Hot air welded, single layer, SBS modified bitumen felt waterproofing, for flat or pitched roofs.

  • Bituminous alternative to single-layer polymeric systems.
  • Suitable for new build or refurbishment, including overlays.
  • Reduces installation fire risk, compared with torch-on or site-boiled bitumen adhesion products. Advantageous for refurbishment of occupied buildings.
  • Capsheet: Spunbond polyester carrier, coated with mix of styrene butyl styrene (SBS) modified elastomeric bitumen, plasticisers and fillers.
  • Life expectancy in excess of 30 years.
  • Available with 10 or 15 year insurance backed guarantee on application, or 15 year manufacturer's guarantee subject to installation and inspection by Bailey. Consult manufacturer.
  • Supplier offers system design, including wind load, U-value and flat roof drainage calculations.
  • Installation by recommended contractors.

Adhesion/ Fixing:

  • Adhesion of system elements to one another and to substrates needs to be sufficient to resist wind suction and building movement.
  • Suitable for mechanical or adhesive fixing or unfixed ballasted applications.
  • Mechanical fixing is preferred on timber, plywood, galvanized steel, or profiled aluminium decks and may be used on screeded concrete (subject to pullout tests), for new build or refurbishment projects, where the existing waterproofing is stripped back to the deck. For overlays and fixing to all other types of deck, bonding with adhesive is the preferred method.
  • Unfixed applications may be ballasted with gravel, paving slabs on rubber pads, or roof planting by others. Gravel 16-32 mm diameter, to minimum 50 mm depth, increasing to 80 mm within 1 m of perimeters and corners. Supplement with mechanical fixings or bonding at perimeter and corners and around penetrations.
  • Falls in excess of 5º: Requirements for mechanical fixing to BS 8217 should be observed.

Resistance to traffic:

  • System accepts limited foot traffic or light concentrated loads associated with construction or maintenance.
