In this video my Builder buddy Doug Cameron is solving a Building Science mystery. He built this new house using his Zip System 2.0 method which should yield a VERY air tight house, but his blower door score is not what he expected. In this video you'll see what we did to find the problem and what was the source of the extreme leakiness. Thanks for watching The Build Show!
