This IKO Ruberoid Torch-On Roofing Venting Layer is a glass fibre-based perforated venting underlay, finished with sand surfacing on the top side and a polyethylene film on the reverse. Its design is specific for use with torch-applied roofing membranes and when used as the first layer of a torch-applied built-up felt roofing system. This provides a positive partial bond to prepared non-combustible substrates.
Manufactured with an oxidised bitumen coating, the IKO T-O Venting Layer is also suitable for use in conjunction with SBS and APP-modified torch-on roofing.

Question:
If you have to fully adhere 450mm around the perimeter where does any moistur e escape to
Answer:
The IKO Ruberoid Torch-On Roofing Venting Layer is specifically designed to provide a positive partial bond to prepared non-combustible substrates. This means that while the perimeter of the membrane is fully adhered to ensure stability and prevent water ingress, the central portion of the membrane is only partially bonded. This creates channels that allow moisture to escape from beneath the membrane, preventing the build-up of moisture within the roofing system. It's important to note that the membrane should be installed in accordance with the British Standard BS 8217: 2005, Code of Practice for Reinforced bitumen membranes for roofing, and IKO's recommendations.
