Kooltherm®: Less thickness, more performance

As architects seek to balance energy efficiency, space optimisation and design ambition, insulation specification has never been more important. When every millimetre counts, choosing a solution that delivers exceptional thermal performance with less material can help unlock a building’s true potential.

Kingspan Kooltherm® is a high thermal performance range of insulation boards for roofs, walls and floors, designed to deliver low U-values with a slimmer thickness than many commonly used alternatives. Whether you’re working on a new-build scheme, refurbishment project or space-constrained development, Kooltherm® can help achieve energy targets without compromise on internal arrangements, aesthetics or valuable floor area.

Supporting specification from concept through to construction, Kooltherm® is backed by a range of technical resources, including easily downloadable technical data sheets, Declarations of Performance and dedicated BIM objects, helping provide confidence throughout the design process.

To simplify detailing, a library of standard construction details for Kooltherm are also available covering common roof, wall and floor junctions for buildings with cavity walls. These ready-to-use resources feature pre-calculated Psi-values, helping limit thermal bridges and achieve compliance with the next generation of Building Regulations and Standards for energy efficiency.

To see how Kooltherm® could perform on your next project, visit the Kingspan U-value Calculator. It provides a simple way to assess the insulation thickness required to achieve your target U-values, helping you make informed specification decisions from the earliest stages of design. Our new updated calculator also makes it easier to compare materials, assess condensation risk and access product data.
