Boyan mark for valor superintendent we're back over here to bed you want to follow up video to the blower door test mode or video actually had comments from our building inspector when he came through here that mark 4 did the best air sealing anybody be seen in the county in quite some time so kudos to everybody who worked out here today you see we've added a 2x6 wall on top of the existing brick found foundation as you can see there's a gap between our sill plate the top of our pastry roll so what we're going to do here is the most important thing structure we're going to fill that with some ruins and shims put those in there and then we're going to come back and throw that the first thing we got to do is clean it out now we're going to finish cutting these shows out of place we're going to take our foam and seal this from the corner all the way across the wall well also at this point make these corners here and the drywall glad to go ahead and crush that in the corner stay in the ball some articles here we're also going to go horizontal we go back so here it is incident we have a space where our framing bus up to an existing masonry chimney what we're going to do is put them fire rated foam in here and then follow it up with some Rossell because we are next weekend now all this may seem tedious but all these golden 1/8 inch caps multiplied over thousands of linear feet really creates a big air leakage at so ultimately that's what we're trying to do then increase the efficiency of it he'll say [Music] how she idiots will snow video where we filled out a smoke correct loss of house and watch smoke weed out our air leakage younger at negative 50 Pascal's with a blowtorch that's one eight thousand one hundred CFM that's roughly equivalent to bus leaving this window open while running pipette so we're at close that might go up keep in mind that we've more than double the square footage on this house so what's wrong wrong 8,000 square feet 2500 square okay P for that lower door test now we're sitting right now about three thousand seven hundred and seventy CFM and negative G passed out originally our number was eight thousand one hundred so we reduced that the event on the Morgan hat while doubling over W square footages it
