IKO easyseal self adhesive Vapour Control Layer is a high performance vapour control layer. It is composed of a polyester reinforced aluminium core, coated with a rubber modified, self adhesive bitumen coating. The membrane is protected on the underside with a release film backing and coated on the top surface with a fine mineral finish. A minimum salvage of 75mm width, protected with release film, provides a quick means of completing side laps.

Please note: the IKOpro self adhesive bitumen primer will be required in order to activate the adhesion on this product.

Application
Built-up systems including Systems S-A VCL should be installed in accordance with BS 8217: 2005, Code of Practice for built up roofing and to IKO’s specifications Systems S-A VCL is bonded to the substrate by removing the release film on the reverse of the material to expose the self-adhesive coating. All roof decks must be clean and dry, and must be primed with IKOpro Bonding Agent and allowed to dry, prior to the application Systems S-A VCL. As with all self-adhesive membranes, Systems S-A VCL is easiest to apply at a temperature over 10°C.

Side laps of Easyseal SA VCL are self adhesive under normal conditions. However in cold weather or if the self adhesive lap has become contaminated, hot air equipment should be used to ensure the laps are fully sealed. End laps should be heat welded using hot-air equipment. If the VCL is to be left exposed as a temporary waterproofing layer, both side and end laps must be heat welded to ensure they are fully sealed. To assist with installation during cold weather conditions, materials should not be stored on the roof overnight.

Storage
IKO EasySeal Vapour Control Layers should be stored on end, on a clean level surface away from excessive heat and under cover. Self-adhesive membranes should be stored between 5°C -24°C for 24 hours prior to use.
