Description

Self-adhesive reinforced polyester elastometric bitumen membrane to be used as an underlay to Proteus capsheets or as the vapour barrier to the Proteus built-up roof system range when installing on to timber or concrete decks.


The upper surface is finished with silica sand and the underside is a protective removable film. A bond is achieved by removing the protective release film to the underside of the membrane adhering it onto a suitable deck or insulation board preprimed with Pro-Prime® SA.


Features and benefits:

  • Flame free, self-adhesive application.
  • Low temperature flexibility at -15°C.
  • 2.55 kg/m² with high tensile strength.
  • SBS modified bitumen.


Proteus Pro-Felt® SA Underlay Sanded should be installed in accordance with manufacturer recommendations and all relevant national standards and codes of practice, including BS 8217: 2005 – the code of practice for reinforced bitumen membranes for roofing.
