The IKO Easyseal Heat-Activated Fully Bonded Underlay comprises a polyester-reinforced carrier coated on either side with heat-activated bitumen SBS elastomeric coating. It has a fine mineral upper surface and a 75mm release-film selvedge to facilitate lap-joint installation. A release film protects the heat-activated coating on the underside and provides a full bond to primed substrates.
The IKO Easyseal Heat-Activated Fully Bonded Underlay is for use as a reinforced bitumen underlay within built-up roofing systems for new build and refurbishment, commercial and domestic projects. It is suitable for roof pitches up to 5° if reliant on adhesion alone.
The underlay can be used with all associated detailing, abutments, internal gutters, and penetrations as part of a two-layer built-up roofing application. It may also be considered for use on main flat areas in cold roof build-ups.
For roof pitches over 5°, the underlay should also be mechanically fastened in accordance with BS8217 Table 5. This underlay must be used in conjunction with any IKO SBS torch-on capsheet and be installed in accordance with IKO recommendations.
