IKO Easyseal Self-Adhesive Partially Bonded Underlay

IKO Easyseal Self-Adhesive Partially Bonded Underlay is used for main roof areas in warm roof constructions beneath IKO Easyseal Cap Sheet or IKO Easyseal Pro Cap Sheet; the partial bond feature works effectively to prevent potential blistering of the underlay and the cap sheet above.

IKO Easyseal Self-Adhesive Partially Bonded Underlay is a high performance, glass-fibre reinforced carrier with a heat-activated bitumen SBS elastomeric coating. The underside has a self-adhesive bitumen coating (protected by a release film) that provides a 40% partial bond to primed substrates, it has a 75mm selvedge that facilitates a full bond and rapid installation of the lap joints. The upper surface is protected with a polythene film that facilitates rapid bonding of the subsequent self-adhesive waterproofing layers.

The adhesive coating to the underside is activated when it comes into contact with IKOpro Easyseal Bonding Agent to give a guaranteed bond.

The IKO Easyseal Flat Roofing System consists of seven high performance membranes. IKO Easyseal Roofing System has been designed to remove the requirement for hot bitumen and or naked flames for anyone installing roofing membranes.
