Spray Foam In The New Shop! 

I think the only covering requirements are for residential (commercial may have something similar). But my understanding is that it is not just any covering, it has to be a fire retardant. Typically, people use intumescent paint or drywall. The reason is that foam burns easily so you need something to slow it down. They also make the in pretty light colors so the shop isn't so dark.

5:48 that would be *compression* 😁

What kind of screws did you use to screw your 2x3 onto the metal thanks

I'm no builder so excuse my ignorance of naming conventions. Up at the very top you have those bars going across, obviously for reinforcement. They look like metal beams or whatever.... Someone was building a van out and had spray foamed like you did and couldn't figure out why heat was still radiating inside. Some to find out....metal was transferring heat like metal rods via the screws and metal reinforcements if that makes any sense. Basically it made something akin to heating elements. I would image that since heat rises it won't be an issue for you but I would put a laser thermometer on those things for fun.

I looked into spray foam for my 24x36x10 and the cheapest I found was $8,500 and that wasn't lock in that was lowest could go up depending on the building when they got here

You use a 2x3 and a 2x4 so to have the extra on one side

Does your attaching the 2x3s to the metal studs void your warranty?
