Kooltherm 'Kelvin'

As we look to balance the energy efficiency, space constraints and design ambition of our buildings, insulation choice 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 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 projects from concept through to construction, Kooltherm is backed by a range of technical resources, including easily downloadable technical data sheets, Declaration of Performance documents, and dedicated BIM objects, helping provide confidence throughout the construction process.
