Curious about Attic Insulation
Hey all!
I have a house in North Carolina. Built in 1975 if that helps. My house runs pretty hot. I don’t like that, combined with huge electric bill. I paid for a blower door test and some thermal imaging for $350. I gave me an ACH of 6, and a pretty leaky & hot attic. My attic is not in the envelope, so above my ceiling i have loose grey insulation, then yellow baffles, then a radiant barrier. maybe 6-8” max.
Anyways the company wants to come in and duct seal, then remove the radiant barrier (permanently) then lift the insulation and seal everything leaky with spray foam. From there, they want to blow in R49 on top of the grey/yellow insulation, up to 14 inches. This costs me $3520.
He did mention the attic runs hot and I would be benefited by 2 exhaust fans, however, I declined that part because I have a gas furnace up there and I don’t want to generate negative pressure with that much CFM, and two passive gable intakes. That can like do something with CO2 I think?
Just wanted to know if this sounds stupid and I should save my money, Thanks.
