IKO Glass Fibre Underlay (3B)

IKO Glass-Fibre Underlay is a waterproofing membrane, consisting of a strong glass fibre base coated with oxidised bitumen. It is sand finished on both surfaces. Used as an economical underlay (or intermediate layer) in a built-up felt roofing, and is usually fully bonded in hot bitumen. It is also used as an underlay to bitumen shingles in a pitched roof application.

This range of IKO glass-fibre roofing membranes consists of underlays and cap sheets, complying with former BS 747: 2000 Type 3 where applicable. The products usually have an oxidised bitumen coating and are either sand or mineral surfaced. These products are usually applied with hot bonding bitumen, or cold bitumen adhesive.
