Introducing our New & Exciting Kingspan Kooltherm Lower Lambda Range….achieving a Lambda Value of just 0.018 W/m.K across all thicknesses.

Here at Kingspan Insulation we are always striving to improve our products to make sure our customers get the best solution for their project. We understand that the industry continues to evolve and so do our products.

With that in mind we have revolutionised our rigid insulation technology with the introduction our New Kooltherm low lambda product range for floor, wall and soffit applications; delivering premium thermal performance with a minimal construction thickness.

The advanced composition of Kingspan Kooltherm lower lambda products ensures architects and builders now have even greater freedom to achieve spectacular designs, with inherently outstanding fabric performance, without having to compromise on internal living or working space. 

The new products have a lambda value of just 0.018 W/m.K across all thicknesses. Here are the thicknesses required for commonly used insulation materials to achieve the same level of thermal performance:
