Air Sealing The Attic








I'm about 1/2 of the way through the attic. The difficult half. I've been working for about 6 hours so far and gone through as many cans of foam. I probably have 5 left of just air sealing. I'm also removing the balsam wool bags as I go. Then I'm going to make a 2' dam out of plywood around the hatch. I'm not air sealing the top plates at the perimeter. It's just too much of a PITA so I'm going to get the 2 part spray foam guys where I work to squirt those tricky spots.

It really is a shame I didn't take blower door measurements before I started all of this work. I still haven't run a blower door here. Maybe I'll look into getting one here this weekend to aid me in my attic air sealing.

EDIT:

Oh yeah. The heat pumps failed in January. Not in a mechanical sense. In a financial sense. $380 electric bill. I have never seen anything like that. Those damn things are off until it gets hot out. I guess they don't like the way I ask them to bring the house up to temp twice a day.
