Anyone here have their entire house spray foamed?

I do. Built in 2007, when spray was just getting big. Raised home. You have to plan it from the beginning and if you use gas, you need to bring in fresh air. We have a 2 stage 21 sear HVAC system. We have be pleased but in hindsight, we would probably have been ok using cellulose in the walls on the north and east elevations and saved a large amount on insulation cost for the build.

we built in 2006 and spray foamed all exterior walls. Heard a bunch of conflicting opinions about doing this in the attic. House needs to breathe and all that stuff... who knows. Very happy with the spray in wall insulation.

What do you mean?

Those were his words, not mine I don't know much about insulation. Apparently if a house is too tight it can affect air quality inside. He said that it can restrict fresh air from the outside from coming in if your house is too "tight". He got tired of having to run his bathroom vents or kitchen hood while he was at work.

Can spray foam make my house too tight?

I have 2 air handlers, one is under my house. I have a 12"x12" air return outside the home. This provides fresh air into the home.

I used spray foam in my walls. Big time energy savings when compared to the other houses in my neighborhood that didn't. I've been happy with it. If I could do it again I'd spray the roof decking as well and insulate the attic space. More energy savings by having your HVAC in a semi conditioned space.

Lots of conflicting opinions by contractors or HVAC folks, mainly by people who are uninformed in my experience. As others mentioned you need to re-size your HVAC and bring in an air exchange but worth it you can find someone who knows what they are doing.

I bet the window issue is the result of condensation

I used spray foam in the exterior walls only. Traditional blown fiberglass in the attic and fiberglass batt in the interior walls/garage/etc.

With the gas appliances and attic ventilation concerns, this was the best route IMO.

Tight houses don't breathe which can lead to moisture issues. Lots of opinions on whether or not this is truly a problem.

My house is tight and I have a problem getting a draft going when we build a fire in the winter. Either have to crack a window or leave the fire going off of gas only for about 20 minutes. otherwise itll smoke up the whole house.

Ive watched his videos. He is adamant about spray foaming the roof and how much it makes the house efficient with the AC unit being within an insulated area.
