 Do we install a heat pump yet? He goes, no, it's on the back of my truck. I said, well, she said it's warm on the second floor. He goes, well, I guess so. It was a wind tunnel before we got here. He had spray foamed and sealed. The house was 15 degrees warmer, and the heat pump wasn't even running. It's not drafted anymore. Yeah, so spray foam is awesome. I was just telling the guys during our break, we're on this Facebook Live, so we're talking, and got set aside with talking about spray foam.
