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.
