Kingspan Kooltherm K118 Insulated Plasterboard
Kingspan Kooltherm K118 is a premium insulated plasterboard that combines insulation, drylining, and vapour control in one high-performance board. As Kingspan’s thinnest insulated plasterboard, K118 provides outstanding thermal efficiency while helping to save valuable internal space.
Ideal for both new builds and refurbishment projects, Kooltherm K118 can be mechanically fixed or adhesively bonded to a variety of substrates, including solid stonework (subject to moisture assessment), brickwork, and timber framing. It’s also an excellent choice for under-rafter applications in pitched roofs, helping to maximise loft and attic space without compromising insulation performance.
Offering a simple and effective way to upgrade thermal performance and improve energy efficiency, Kingspan K118 Insulated Plasterboard is perfect for achieving a smooth, ready-to-decorate finish while maintaining superior insulation standards.
