IKO Easyseal Self-Adhesive Partially Bonded Underlay

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 Capsheets or IKO Easyseal Pro Capsheets. The partial bond feature works effectively to prevent potential blistering of the underlay and the capsheet 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 also 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 Systems have been designed to remove the requirement for hot bitumen or naked flames for anyone installing roofing membranes.
