The IKO T-O Venting Layer is a glass fibre-based perforated venting layer with a sand surface on the topside and a polyethylene film on the reverse side.
The IKO T-O Venting Layer is specifically designed for use with torch-applied roofing membranes.
When used as the first layer of a torch-applied built-up felt roofing system, it will provide a partial bond between a non-combustible substrate and torch-applied bitumen underlay.
