I have a construction company, but always put rockwool, fiberglass, etc. in my houses. For my personal house I'm looking at spraying in foam? My only concern is condensation. Anyone have any good/bad experience with spray foam? TIA

I had it done in my attic a few years back when Obama was paying for it. I got no complaints

Just curious here. Are you saying that what you sell your clients isn't good enough for your own place? Or is there another reason.

I am about to hire a builder and I would be mighty pissed if I found out he had different standards for his place and mine.

I am hoping there is a reasonable explanation like "we don't do that type of construction." Help me restore my faith.

Applied correctly, and integrated into the design properly, there are no cons.
Condensation is a non-issue. Make sure you get a competent HVAC company that understands foam.

Foam is the best insulation on the market.

A neighbor and I built similar 2 story new construction homes in 2007 ~2600sf. Pier and beam foundations on both homes. He put in Rock Wool insulation, I'm not sure the type of a/c's he installed.I put in spray foam and 21 sear A/Cs with 2 stage blowers. You want an a/c unit that runs on both a temp point and a humidity point. I sprayed everything, ceiling walls and under the home and my electric bill averages ~$160 year round. I can go in the attic in the middle of summer and the it is 84 degrees. I paid about triple in insulation cost that he paid...

My parents just built a house and had the foam put in. After a few months, they wanted to sue the contractor because they had mold. I told them to get a dehumidifier and it solved their problems. Make sure you have a dehumidifier in the budget.

I bought a house back a few years back that was built in the mid 90's. I had foam sprayed in the attic like 2 summers ago and my electric bill has never been over $150. It's expensive on the front end but it pays off.

My current home is modern. So no need. But we put it in our last house which was pier and beam and 100 years old. It made a huge difference. The house almost wasn't livable prior to doing it.

A house I built in the past we used Icynene insulation in the walls and on the backside of the roof decking. The ceiling was uninsulated.

It worked fantastic and the attic becomes a "tempered" space about 10-15 degrees hotter than the climate controlled space but with a humidity level much like the climate controlled space.

Icynene at the time was pretty expensive but long term it would pay off. We saw utility bills one half of similar sized homes.

Sealing infiltration losses can realize significant savings.

Only downside I am aware of with insulating the backside of the roof deck this way is perhaps losing some shingle life due to the shingle temp being higher as the shingles cannot radiate heat off the backside.
