Is this shop attached to your house ? you said you have cars in it ,
Lawnmowers , other flammables?
Think about it . You have a lot of money invested ,why skimp ?
Safety IS a big factor, ALL the other alternatives to a sheetrock
ceiling are very dangerous ,the smoke ,and hazardous fumes from
them will kill you.
This is the BEST advice that was given to you about the project :
If you plan on spending any time or storing any of the usual finishing
fluids in your shop, you should use 5/8 or 3/4 drywall.
5/8 is usual code for a fire barrier between garage and house. It may
help contain any fires until help got there.
The other materials recommended are all fairly flammable.
just my $.02,
I recently had a new 24x34 garage built. I will use it as a shop and for
parking two cars in the winter. I'd like to have some kind of ceiling in
it, to reflect light down, and to keep heat in during the winter.
Finished, painted drywall would look the best, but be difficult to put
up. I'd have to rent a jack, and I constantly be worried about the jack
damaging my newly painted floor. But I'm not worried about it getting
dented (as I've read here before) because my ceilings are about 10.5
But what are the other alternatives? Plywood? (OSB more likely). I will
be putting insulation in the 'attic', too. Not sure if it will be bats
or blown-in yet.
Also am thinking about what I should put on the walls... that will
probably be drywall, I think.
Thanks for any suggestions.
