In the last year or so I’ve come across a few articles saying spray foam is creating problems.
'I wanted to cry': Devastating risks of spray foam insulation hidden from Vermont homeowners - VTDigger
…
”With 25 years of building experience, he knew that peeling paint indicated the presence of moisture. But the location was odd — that trim underneath the overhang should stay dry. So he grabbed a ladder and a pry bar to take a closer look.
His stomach dropped…”
Everyone I spoke to agrees that spray foam is better suited for some jobs than others. Instead of the top of a home, look to its bottom, they said — particularly old rubble-walled foundations.
“That’s where spray foam really shows up as one of the best options available, without going to more heroic measures that can cost a lot more money,” said Racusin, New Frameworks’ building science director.

Oh my......
Well, I guess I'll just keep on keeping on in my old remodeled schoolhouse home with its 'normal' old house issues.

You still live in your old school house? Hopefully they gave you a bigger desk. 
30s here this morning. Cold on the uninsulated floor. 70 in the cabin. Pretty good access for spray foam kit, maybe not after reading this..

We have about 940sf, any wall work Ive put in f-glass, not near enough in the ceiling and we poured in cellulose down from attic into the wall cavities. Some new windows too, but all in all it is pretty basic old school ( )
And our nat gas and electric combined run about $2200 a year; not too bad I think.

That’s probably about what I pay at my grid house. But I’m tight wadding. It too has fiberglass in the walls, slab floor. Roof is tar and gravel over about 2 inch fiberboard. That’s it, no wood sheeting. All ‘50s stuff in poor shape. So far I’m not using the in slab gas heating, just the wood stove in the master bedroom. Last year we had a live in nurse for awhile staying in another bedroom so I did have the in floor heat going. Sure was nice (not to mention cooked meals) but the gas bill was like watching a propeller spin. And it takes a day or two to heat the concrete floor, we’re just not there enough to make it worthwhile.
Even the bedroom wood stove, same Arrow as here at the cabin, struggles with the single pane windows and slider. With the door closed it’s still empty before morning and the room is cold. Makes me appreciate the the newer cabin build. Night log will keep it warm all night, quick top up in the morning.

Quoting: paulz struggles with the single pane windows and slider
That reminds me of a lot of the older homes here in NM. They used single-pane metal frame windows with a grid of panes in many homes back in the 40s and into the 60s. They can frost up nicely/badly in cold winter weather.
This is a typical old corner window found in many kitchens here. All steel, single pane. Usually casement style. This is in a concrete block wall but they were used in stick frame construction too.
If carefully removed we could eventually find someone who would pay nutty $ for refurbishing and re-use.

From what I gather the article says basicly a house needs to breath a bit.

Another reason to put in a fresh air entry for the stove?
