Kingspan Kooltherm K118 82.5mm Insulated Plasterboard

82.5mm K118 by Kingspan Kooltherm is a high-performance insulated plasterboard engineered for mechanically fixed and adhesively bonded internal wall drylining. This all-in-one system combines insulation, drylining, and vapour control in a single board, delivering a thermal conductivity of 0.019 W/mK. The slim profile makes it ideal for Internal Wall Insulation (IWI) projects where space is limited, and it performs effectively on solid masonry, brickwork, and existing linings.

The 82.5mm Kooltherm Kingspan offers significant advantages for renovation and new build work. Its compact thickness ranks among the thinnest Internal Wall Insulation options available, making it perfect for properties where external insulation is not feasible. The integrated drylining and vapour control layer streamline installation, whilst the lightweight construction simplifies handling and fixing on site.
