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...
