80mm Kingspan Kooltherm K121 Facade Board - Rainscreen Phenolic Insulation Board - 1200mm x 2400mm

80mm Kingspan Kooltherm K121 Facade Board is a premium-performance rigid phenolic insulation board designed for use behind facade and rainscreen cladding systems. Featuring a fibre-free thermoset phenolic core faced on both sides with low-emissivity composite foil facings, it delivers outstanding thermal performance whilst helping to minimise wall build-up thickness. With a thermal conductivity as low as 0.019 W/mK, Kooltherm K121 is one of the most thermally efficient insulation products commonly used in facade applications. Its slim profile allows demanding U-values to be achieved with less insulation thickness, providing greater design flexibility and helping to maximise usable internal space and natural daylight.

Suitable for both new-build and refurbishment projects, Kooltherm K121 is lightweight, easy to handle and install, and offers excellent resistance to water vapour and air infiltration. Designed specifically for use behind ventilated facade and rainscreen cladding systems, it forms part of the Kingspan Kooltherm range of high-performance insulation solutions. Kooltherm K121 Facade Board is a high-performance insulation solution for modern facade systems, delivering exceptional thermal efficiency, reduced wall thickness and reliable long-term performance in both new-build and refurbishment projects.
