There’s a fear abundant in the general public that houses “need to breathe” and they shouldn’t be built too tight, but what does that mean? House wraps, all-in-one Weather Resistant Barrier (WRB) sheathing, tapes, foams all can help seal a house tight, but then it must be ventilated right. And insulation in the cavities of your walls is good, but how can you add a continuous jacket of exterior insulation to really up your family’s comfort and energy efficiency? Every home is a system, and the skin of a home is as critical as the skin of your body.
Featuring a consulting/testing visit to Anna’s new house, where she’s having some trouble with moisture condensation, high performance enclosure expert Johnny Rezvani of 475 Building Supply, Matt Risinger of the Build Show, and the cherry on top: a field test of wind driven rain, or ‘Hurricane Test’ by Landus Bennett, using a pressure washer and 5 blower door tests at the same time.
