A FABRIC FIRST APPROACH TO PART L

Taking a fabric first approach is a sustainable and proven low-cost solution to reducing carbon emissions. Use our PSI calculator to find out the impact of substituting standard lintels with our thermally broken range.

THERMALLY BROKEN LINTELS

Our Supatherm range of thermally broken lintels can deliver a 75% reduction in heat loss compared to standard lintels. To put this into perspective, this means that a small detached house (105m2) substituting standard lintels with thermally broken lintels could deliver the same results as upgrading to triple glazing.  On a large detached dwelling (304m2) it would enable a cavity wall reduction from 150mm to 125mm delivering savings on insulation and masonry ancillaries.
