IKO Challenger is a simple range of reinforced bitumen roofing membranes that are suitable for domestic and commercial applications. They have a polyester base for toughness and durability.
The sand-surfaced IKO Challenger Underlay can be used where additional surfacing in the form of chippings or promenade tiles will be provided.
These membranes have a green surface and are available for use as a capsheet without the need for additional surface protection.
