Insulation/Spray Foam

[Motofish43]

I can't answer to the VOC aspect. I can tell you a good 2" of closed cell will make a big difference in sound and temps. It solidified my 40x60x16. Herr in zone 5B I heat the entire shop with a single residential wood stove and cool with a evaporative cooler. Prices have come down in my area significantly as there are now multiple companies offering spray foam. While it's still not the most affordable way I believe you get what you pay for with spray foam. Batt/blow in insulation doesn't seal and add to structure like closed cell.

I spray framed my shop seven years ago. Just did the gables and under the roof. Did 2" of closed cell. Walls are r19 batts. Shop rarely goes below 40 degrees. I have a ng heater that will bring it up to 60 in a couple hours. Never noticed any off gas. Also a quick note on insulation. There is a point of diminished returns. Meaning r38 is not 100% better than r19. Something to keep in mind, especially for a shop that is not heated everyday.

What are you guys getting quoted for pricing on this? For. A 2500 sq ft house near bzn you’re looking at $30-40k for walls and lid sprayed

How does mineral wool/rock wool fit into this conversation? I've heard it doesn't breakdown like traditional fiberglass can and is still a cheaper option than spray foam.

40x60x16 walls and roof $5200. Colorado. That was during the pandemic too. I'm told prices are more competitive now from guys that are building these pole barns.
