Kingspan Kooltherm K106 Cavity Board is an elite full-fill cavity insulation that is unrivalled in terms of thermal performance. Specifically designed for full fill applications that have a residual 10mm cavity, this phenolic insulation board delivers a lambda value of just 0.018 W/mK. The Kooltherm K106 insulation boards have a composite foil facing on one side and a polypropylene fleece on the other. This fleece is water-tight and vapour, preventing moisture from penetrating the building envelope. These Kingspan K106 cavity boards are made using a particular blowing agent that instills in them low GWP and zero ODP, which means minimal environmental damage. The boards are sized at 1200mm x 450mm making them light and easy to install. They have a compressive strength of over 100 kPa at 10% compression.
