Energy modeling simulation of heat loss through thermal bridging
Efficient home design

What is a thermal bridge and why is it so important to break it?

...thermal bridges: It is not only sensible to address thermal bridging in construction, it is becoming law. Recent revisions to building codes have increased the thermal requirements of building enclosures in many regions, including requiring a thermal break. Contrary to common assumptions, the insulation value...

...thermal bridge', and preventing it is known as a 'thermal break'. Heat loss through thermal bridging When we mentioned at the beginning that these factors can work in conjunction, that is because the cold surface that results from the high conduction through wall studs and other thermal bridges can absorb radia...
