Kingspan Kooltherm K118 Insulated Plasterboard is a premium 2-in-1 insulation and drylining product for masonry walls and timber frames. Blowing all other insulated plasterboards out of the water when it comes to thermal performance, the K118 boasts a phenolic core insulation with a lambda value of just 0.018 W/mK.
The Kooltherm K118 boards can be mechanically fixed or bonded using the dot and dab method. As a product incorporating both insulation and plasterboard, they save time by allowing you to insulate and dry line in one easy application.
These Kingspan K118 insulated plasterboards have a composite foil reverse facing, allowing for effective vapour control. They are also manufactured sustainably, with non-deleterious material. Boards are 2400mm x 1200mm in dimension, with thicknesses determined by the combination of insulation and plasterboard.
