Improved Lambda value for XPS insulation

Demonstrating high compressive strength, low water absorption and improved insulating properties, Sundolitt’s XPS is utilised for load-bearing and insulating protection for buildings and construction, in a wide range of applications.

Tests carried out by the Technology Institute in Norway – a registered laboratory for thermal conductivity testing – has shown improvements in the thermal conductivity of Sundolitt’s XPS material.

The improved Lambda value of 0.033W/mK at 50mm extends across the range between 200 – 700kPA and will assist clients in achieving improved U values for construction applications. Sundolitt’s XPS also has the capability to maintain its insulating performance even in an environment of high moisture content. As well as straight edged boards, Sundolitt’s XPS boards are also available with a ship lap edge, which prevents thermal bridging and stops capillary action.

Philip Cheshire, General Manager (UK), at Sundolitt, comments, “We are delighted to announce the improved thermal conductivity testing results of our XPS material and are already working on client projects where this enhanced property was an important part of the specification.”
