Anyone here have their entire house spray foamed?

If so, what are your thoughts? Worth the extra money?

It's tough to move around, but we stay warm.

Yes it is worth it.

I spray foamed your mother last night.

yep, make sure to get client testimony for the contractor. They do it wrong, and your sheet rock will be bowed out off the studs, and pink foam will be oozing out from behind your trim/molding

Your ole lady so fat she’s rubbing the walls?

I have had a coworker do it for his whole house and he feels it wasn't worth the added cost. I have done it in my basement. I can only give my opinion. Here goes:
1) No, it is not worth the extra money for exterior walls and the attic. The attic can be worthwhile if you are wanting to do a sealed attic but if you have a ventilated attic, I'm not a fan.
2) It is the only worthwhile choices for rim joists.
3) It is the only worthwhile choice for basement walls
4) SIPs are just about as good as it gets if you can do it: LINK
5) If you want to keep costs under control and still get excellent results, I'm a big fan of "dense packed" cellulose in the walls and blown cellulose in the attic. dense pack cellulose provides great sound insulation and very good infiltration reduction. Blown cellulose in the attic has an R value that actually increases as temperatures drop.
6) There are many lawsuits out there for spray foam. If you do it, make sure you get a VERY experienced contractor. You can get everything from long term bad smells all the way to sick building syndrome where everyone inside gets sick from the improperly mixed foam.

I forgot to add, make sure you get infiltration levels measured before sizing your HVAC. You may need ERV/HRV added to the HVAC system if your envelope gets too tight.

existing home?
new construction?
would it be possible for you to give us any less information?

85% of your energy savings will come from the attic being sprayed. If you think the remaining 15% savings will pay for itself by spraying the walls too then go ahead. I did the math on my new construction and it was going to take like 24 years to make up the difference by also spraying the walls.

I did mine. It works great, but my HOA made me take the sticker off.

I think you save 10-15 a month on the electric bill. If you think it’s worth the extra cost for the upgraded a/c and cost to spray the whole then go for it. I personally didn’t think the ROI was so I did fiberglass

If done correctly, it is worth it. My bill at home currently home we built is considerably larger but my utility bill is almost half. When I received our estimates, the foam estimate was not as bad as I thought. With a 2 story home, it was a no brainer for us.

i live in an old leaky home that i am renovating room by room. about a year ago, i did a bedroom i sprayed the underside of the floor with closed cell, then the walls and ceiling (not roof) with open cell. i also spent a lot of time sealing the leaky old windows.
there is a very noticeable temperature and sound difference when you walk into that room. I did dense pack cellulose in a previous bedroom, but did not finish the windows as well, nor did i foam the floor.
for my purposes, the leak sealing aspect of foam (especially floor and ceiling) is as important as r values.
i will probably foam the rest of the floor and ceiling, but am not sure that foam in the walls was worth the price difference. cellulose is cheap and DIY.

Sure, we can't find the fridge, or the dog, but the electric bill is lower.
