Kingspan Kooltherm K118 Insulated Plasterboard is one of the best insulation plasterboards available,  developed with a fibre-free and rigid thermoset phenolic core. Kingspan Kooltherm K118 Insulated Plasterboard offers lower lamba values that makes it retain more heat when it comes to plasterboards for internal wall insulation.

Kooltherm K118 has been made using plasterboard bonded to its front surface and a reverse facing foil, this has been done with quick response heating in mind. The reverse facing side is a low emissivity composite foil which improves the thermal resistance. It provides a level of matchless performance among rigid thermoset insulation materials commonly available with just 0.018 W/mK's thermal conductivity across all densities. This insulated plasterboard has a dry lining, coated by a strong adhesive bond for protection.

Kingspan Kooltherm K118 Insulated Plasterboard is environment friendly as it is produced with a blowing agent with zero ODP (Ozone Depletion Potential) and very low GWP(Global Warming Potential). It is highly recommended for being easy to install and handle, as well as for being environmentally friendly.
