Efficient home design

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

...reduced to R-7.4, a value only 35% of the nominal ". If putting heat conduits on either side of batt insulation reduces their performance even by half, that means you essentially paid double the price for the R value you think you purchased. So your money may be better invested by employing alternatives. Building c...
