 This is Nate Adams with energy smart home performance, and I just finished the air sealing that I needed to do up here So let me show you around what happened. So this is the gable end wall and hold it calm. I'm shaking But this is the end of the house right here and The cavities here for the walls were open So I stuff fiberglass down in them and then foamed over the top. So now when we dense pack the walls blowing cellulose into the walls It won't be able to come up in here and we'll be able to get a nice tight pack inside there So that's really important to do Also, this house had a big gap where you can see that foam up there Where bats could come in So I got that all sealed up all the way around and Then the other air sealers had to go on the bathroom is basically right under this area here So you can see there's a plumbing stack there and a plumbing stack there And then there's also an open wall cavity under this so that all got foamed up foamed around the bathroom fan And then The last big piece was this big area of foam right here This was the ceiling over the Upstairs bathroom so it dropped down it went down one flight and then over and the problem is you can look down Inside a whole bunch of the wall cavities in there So that has to get sealed up so what I did was staple some landscaping cloth across this and then foam the top and Presto we have a nice air seal and We can just blow over top of this and not worry about it anymore But I'm not a hundred percent sure of the air seal so my next step is I'm going to go turn the blow it around and See if I missed anything up here. So hopefully I didn't but you never know nobody is perfect
