Polyester Based Cap Sheets and Underlays
The Challenger products form a simple range of roofing membranes, which are suitable for domestic and commercial applications. Challenger membranes have a polyester base for toughness and durability and an oxidised bitumen coating. Green and blue/grey slate surface membranes are available for use as cap-sheets without the need for protection; sand surfaced membranes are used as underlays or where additional surfacing in the form of chippings or promenade tiles will be provided.
