Product Description

IKO Challenger Polyester 180  Sand is used as a  vapour control layer for adhered IKO Polymeric roofing systems that can be applied in the pour and roll method. The membrane has a polyester base for toughness and durability and has an oxidised bitumen coating. The sand surfaced membrane is an ideal surface to receive adhered thermal insulation boards. 


  • The membrane should be installed in accordance BS 8217: 2005, Code of practice for reinforced bitumen membranes for roofing, and to IKO Polymeric specifications.
  • Application is by traditional pour & roll methods.
  • Hot bitumen is poured onto the substrate in front of the roll, which is then unrolled into the bitumen, spreading it to give a continuous coating for the full width.
  • The membranes are applied with minimum 75mm side and end laps.

Please note, Challenger membranes (oxidised bitumen coatings) if used during the winter months should be stored between 10°C and 20°C for 24 hours prior to use and not applied at temperatures below
