I just closed on a new piece of property today. It has a 2 car garage on it. It is a all steel building with no insulation. I want to put some up. What kind of insulation would be great for sound and heat barriers? I don't want to make my neighbors mad and their two homes are less than 15 feet from the garage.
On the same building, what is the best heating the building? Propane radiating heaters, wood, or electric?
I do plan on doing all kinds of machanical work, body work, and painting on my automobiles.
For heat- it would probably be electric since you will be working with fumes that can be flammable and you don't want to have to worry about CO posioning either.
Blueboard is the mositure proof drywall kinda stuff they use in shower stalls instead of drywall. It will stand up to moisture better than drywall. It may have some other name in different parts of the country. One post here a few weeks back, on insulating garage doors, suggested using foil covered foam board as that would also help the flamability issue. This is a building code issue, and a potential fire insurance issure.
I have seen where blown foam was just stuck right to the inside of the steel. I last saw this in a very large shop in Alaska. All of the wiring was done and then the foam was blown on.
Rigid foam is that flammable? Yikes! I've thrown all kind of sparks on it for about ten years w/o incident. I know enough not to spill gas on it tho'. What about that foil-backed stuff- celotex I think it's called.
Congrats on your new garage. I am jealous. Biggest problem with any garage is it is never big enough!
The foil backed stuff is nice but even it too has to be covered with drywall (by code) or other non-flammable material.
Grinder sparks are probably not hot enough to ignite it, but welding sparks could be.
That said, it is done all the time with no problems as FLgargoyle's post indicates. But if it does, the toxins released will kill you long before heat and flame do.
The curve of the building presents a problem. Hard to hang drywall on! I think some of the spray foams may be less volatile and can be used with out covering. But they are not going to be cheap.
Someone one here has had to have done this somehow.
I dont know if this is possible for you but in our garage we bought 2nd's of fiberglass sheeting from a local fiberglass manufacture. It is about 3/16th thick and we got in lenghts of 12, 14,16, foot long by 4. I think we paid about 4 bucks a sheet. Chemical resistant, flame retardant, rot resistant and durable as anything. When you do your ceiling, your best bet is to use celotex foil faced insulation sheeting. It will brighten your garage up a bit. You might want to plumb all your air lines in the walls also.
They do have a type of insulation that gets sprayed on andthen expands, nice thing about it is you can then shave it down to the thickness you want becasue it dries hard. Dont know that you can DIY but its a thought.

If the floor in not in yet I would do radiant heat in the floor. If it is a suspended gas or propane heater will work well As long as the flame sorce is above 4 feet it will pas most requirments. You can check with your local gas company they will help with the requirements. If you will be generating waist oil clean burn makes a waste oil heater that can be hung from the ceiling and you can run ducts of it if needed. I have been using a gas furnace for 20 years and have never had a problem.
