I’m a state licensed mechanical contractor. The best way to ventilate a foam house is with an ERV or energy recovery ventilation unit. At minimum, outside air brought in through the HVAC system with a damper connected to a specialized controller.
Thanks for commenting Edwin... you are absolutely right... a certain about of "air changes" per day are required for healthy air. I forget the math, but glad you brought it up, least folks forget.
If you are not actively engaging EVERY enemy you encounter... you are allowing another to fight for you... and that is cowardice... plain and simple.
It worked really well for us on a 20 x 20 building and I didn't have to deal with fiberglass insulation.
Money well spent!

Imagine doing that for a living I couldn’t think of anything much worse
The guys spraying were legal Hispanics... the senior of the two has been in the US for 25 (?) years (maybe 48 years old). He has 4 kids, his family is very close... kids going to college... starting businesses etc.
He was a farmer back in Mexico... has a small tract of land here and a few cows... he is looking forward to growing that.
He does chitty work daily... but takes care of his family and dreams.
He earned my respect. I tipped him well.
The younger guy is similar.
These guys have a very good bead on life and will be taking away fortune/opportunity/wealth from the "woke" and the "stupid"...
So be it.

Give a man a fish and he eats for a day. Give a man a welfare check, a forty ounce malt liquor, a crack pipe, an Obama phone, free health insurance. and some Air Jordan's and he votes Democrat for a lifetime.

Steve... what is your rate per SF on closed cell? Assuming a 3,000 SF job?
Thanks
There was no real set SF price, it varied by location, wall height, attic height, vaulted with Proper Vent ceilings, vaulted hot roof, flat ceilings with thin layer then blown glass, flat ceilings complete, thickness, ease of access, etc.

That framing/roofing combo has to be the lightest on the market. I'd be curious what the structural numbers are before and after.
@jameslavish
If you work 40 hrs/wk: at 5% inflation and after 5 years, you need a 28% pay raise or to work 44 more hours (*one full extra week* per month+) to make up the difference.

I ran the calculation... she is plenty strong.
Actually... the lateral wind load is the design failure criteria... (i.e. the foundation can lift at 134 mph, but I hope to bring that number up with the pallet racking).

From a load calculation perspective... foam does not have a number that can be calculated... but 29 gauge side is pathetic... should be better now.

Thanks for posting. I'm guilty of doing what I'm used to doing. I like seeing other options.

We have a 36 x 63 feet garage - built by Morton Buildings. I've been told (by the Morton buildings rep) that the spray foam insulation would eat away the metal. Been told by spray foam person that it wouldn't. They each have conflicts of interest. Find conflicting info online. Anyone know?
Has anybody tried it on a travel trailer? My Weekend Warrior came out of CA and there is no insulation in the floor. I was thinking about having most or all of the underside spray foamed.

If the underside is covered or enclosed after it is foamed. Any solvent, oil or water will slowly destroy it that is kicked up from the road surface otherwise. .

If you prepped the metal PERFECT... and I mean PERFECT... maybe.
As for wear from water and road debris... I can see this a possible... and if separation ever occurred trapping moisture.
I guess if I was insistent on trying it... I would prep the metal... spray an inch or two of foam... add a layer of expanded metal to the frame with tabs and bolts and then do another layer of foam thru the metal to the existing foam.
Might work... I don't really like my suggestion... but maybe???????

I can't imagine how the foam would "eat" the metal.
If anyone told me such a thing I would sit down to a lunch with them... have a couple of beers and gauge the bullchit on various other topics (i.e. bring up politics... then flip sides as a test).
Might be true, but sure sounds like pure crapola to me.
