Insulating /drywall ???

[bmxdukie]

Hi folks. I just finished my back garage with drywall and insulation. I heat with a reznor hanging heater.
On my house i have a 28 x28 un insulated ..
I would like to insulate and finish but no heat. My buddies say it a waste of time and money.
Thoughts?

They are wrong

It doesn't get as cold for as long here, but every winter we see days in the single digits, sometimes below zero. My attached garage is insulated and sheetrocked and no heat. It has never gotten below freezing in there. I think it helps and kind of tempers the outside temperature.

My last house and my new house both had attached garages, both I insulated and drywalled. Never freezes in either one! Definitely a must do.

If you already have the ceiling mounted heater installed, what’s the issue? If you only heat the garage occasionally, then leave the heater for when you need it.

It’s been well over two decades since we had an extreme extended cold snap here in mild Portland Oregon, but there were many hundreds of people who had their hot water heaters in their garages and unheated attached utility rooms who got an unpleasant surprise with frozen pipes – even homes where the plumbing had been there for decades. Do you have any plumbing in the garage, even some that may be hidden in a wall between your garage and house? I know the insulation will help, but garage doors usually leak air badly. And you are in Ontario!

On another cautionary note, I helped a friend of mine with his garage/shop build that he’s now insulated and finished with no heat. He was discussing with me how to add heat and I suggested a ceiling mounted gas unit (I assume) like you mentioned having. He’s a fireman, and the first thing he said was dust in the dry air is a significant fire hazard and those units can cause a dust explosion. Now he’s debating the best method knowing that both sawdust and airborne dust are significant hazards.

If you insulate then it's easy to add heat later. In my garage in Southern Ontario on even a very cold day a couple 120v heaters make it way, way, way more comfortable to work in!

My detached garage is drywalled only. The previous one had nothing.

Drywall alone makes a significant difference. Insulation even more. It will also help the house since the connecting wall won't be loosing as much heat.

Just wait until you pull a warm car into the garage and close the door. It will warm up nicely.

But....

Before you insulate....run any outlets you think you might want. Put them about 54" from the floor so you can lean a 4x8 sheet against the wall and not block it.

Yes insulate it. We insulated my dads detach 30x34 and it gets to -30 Celsius quite regular. The warm vehicles heat is shared through the garage. It’s much easier on them.

Thanks for the replies. I going to finish it.
Haus, my BACK garage has the unit heater in it. To meet code it is a internal combustion unit for the dust fumes issue.
