Description

Torch-on, APP modified bitumen felt waterproofing system for flat or pitched roofs.

  • Capsheet: Tear-resistant spunbond polyester carrier, coated with mix of actactic polypropylene (APP) modified bitumen, plasticisers and fillers.
  • APP modification provides excellent heat and UV resistance.
  • Life expectancy in excess of 30 years. Better whole-life costing than cheaper systems.
  • Anti-root membrane available, suitable for green and brown roof applications.
  • Choice of 10, 15 or 20 year insurance backed guarantee or 15 year manufacturer's guarantee on application, subject to installation and inspection by Bailey. Consult manufacturer.
  • Installation by recommended contractors.
  • Supplier offers system design, including wind load, U-value and flat roof drainage calculations.

Resistance to traffic:

System accepts limited foot traffic associated with maintenance or construction.

Fire performance to BS 476:

When used for flat roofs with one of the surface finishes defined in part 3 of Table A5 of Appendix A of Approved Document B of the Building Regulations (England and Wales) the roof is deemed to be of designation EXT.F.AA.

Adhesion/ Fixing:

  • Adhesion of system elements to one another and to substrates needs to be sufficient to resist wind suction and building movement. Bailey can provide windload calculations if required.
  • System is applied by melting polythene lower surface and bitumen lower surface by torching and pressure.
  • Falls in excess of 5º: Requirements for mechanical fixing to BS 8217 should be observed.
