IKO Systems Torch-Free Underlay
The underside has a self-adhesive bitumen coating that provides a 40% partial bond allowing vapour dispersion between the membrane and substrate and also has a 75mm selvedge that is facilitates a rapid installation of the lap joints.
The IKO Systems T-F Underlay is used as a partially bonded underlay within a built up roofing specification system. It is to be used only for main flat roof areas and roof pitches up to 5° if reliant on adhesion alone. For roof pitches over 5° this underlay should also be mechanically fastened in accordance with BS8217 table 5 or the IKO specification document.
The unique self-adhesive profile of the IKO Systems T-F Underlay allows for a partial bond to be achieved to the substrate therefore reducing the risk of blistering from any trapped vapour.
