Recommendations for attic insulation for older house in south Lousiana
Posted on 5/26/21 at 1:17 pm

House built in 1959, low pitched roof, approximately 2700 square feet living area, single 5 ton AC unit.
I've started researching and it looks like there are 2 main options: blown cellulose to the attic floor, or spray foam to the attic ceiling.
Does anyone have any experience with a similar sized house and shallow roof? I'm not so much concerned with lowering my electricity bill as I am helping out the air conditioner.

I'm in a very similar situation and your house sounds exactly like mine. After recently researching those two options, I'm planning to go with blown in. It's cheaper and I can easily do it myself.
The spray foam provides more insulating properties, but is more expensive and generally not recommended for DIY. I was told by the installer when getting a quote on spray foam that I would need to seal off my attic ventilation from the outside and thus additional modifications to your HVAC would be required. I've also heard the spray foam can shorten the life of your roof.
Good luck!

My house was built in 1980, we moved in 3+ years ago. Went through 2 summers of $400+ average electric bills, peaked at over $550 a few times (non-levelized billing). Got blown in cellulose insulation before last summer and have not had a bill over $300 yet. We do have 2 A/Cs but about the same size house. Had double pane windows installed right when we moved in and those didn't seem to make much difference but the insulation 100% did.

I went Terminex and let them blow it in. 8 inches was $2100. I had like 7 quotes and that was the winner.
2500 sqft.

3k sf, blown in fiberglass to top off existing was $750
Did it last May and have not regretted it, paid for itself last year.
Cellulose was like 3k

We did cellulose right when we moved in. The previous folks avg 250 a bill. Our first two bills have been $120 and $140.

One thing to keep in mind if you’re considering spray foam is that if you have an atmospheric combustion furnace or water heater, they would need to be changed to sealed combustion units before you spray foam, which might be a non-starter.
