Premium Kingspan Kooltherm Insulation Boards
Kingspan Kooltherm offers a wide range of advanced thermal insulation boards suitable for various floor, roof and wall applications in residential and commercial settings.
The Kooltherm range features a fibre-free core and low-emissivity foil facings. This allows the boards to be incredibly thin while simultaneously offering premium performance, contributing to achieving the specific U-value required in UK building regulations.
Like other insulation boards, Kooltherm offers a relatively hassle-free installation if you have some prior DIY knowledge. If you're unfamiliar with the Kingspan Kooltherm range, please see our size and application breakdown below:
