My attached garage has an insulated door, I also insulated the one exterior wall. However, I have a lot of air leaking from around the door as the seals are bad, that's a project for next summer.
Right now my garage temp is 10C and it goes down to 7C on very cold days. We also use the garage as a primary entrance, so it opens frequently.
I recently redid the interior wall insulation, which will actually keep the garage colder, because less heat will transfer from the house.

In my old house we had no insulation on the walls or ceilings and no insulated garage door. The garage was bitterly cold....almost same temperature as outside.

We bought a Garaga insulated door that was draft free but it only raised our garage temperature to maybe 4-5 degrees better than outside.

Our current home we have an insulated door, walls and ceiling and the garage is usually about 15 degrees warmer than outside.

Let's put it this way: who needs an additional refrigerator in the winter when you got the garage?

On a day like today with zero outside, mid-digits. Without a thermometer, hard to know, but I'd say it's probably about 6 deg in there.

Tis banana is IRIE

10% off is cold, 50% off is warm, 75% off is hot, but FREE IS RFD!

Never bothered to check the temperature in the garage ... it's not like its a mancave in there.

Insulated walls ... garage door is still the cheap builder crap.

But it's south-facing .... so it is warmer than my neighbour's across the street.

My garage is uninsulated roof and walls, and offset as it is a side split bungalow and only shares about 15 feet of one side wall with the main house.

Temperature is about 4-5 degrees celcius above outside.

There is no heat source into the garage so being uninsulated and no floor above the garage it's likely the best its gonna be.

My garage in a single detached 1-car garage home, is currently 7 degrees celsius; and 1 degree outside. That is based on a thermometer reading on the inner most part of the garage next to the door into the home. I'm sure if I place it at the front where the garage door is, it might be slightly colder.

That's with standard builder thin plywood garage doors or whatever they use. No insulation, and no seals, and can see obvious gaps when closed (only 3 years old the home).

It was -20 here overnight this last weekend, and my detached garage stayed above freezing. It’s a 1939 double car garage, with wood chip insulation (single pane windows, insulated large single door). I did turn on my electric heater during the days, which got it up to a temp of about 15 degrees, but turned off the heat at night since I wasn’t actually in the garage doing stuff.

In my experience, insulation makes a significant difference. Without that, you’ll stay pretty close to ambient outdoor temps. With insulation but no heat, you’ll get a gain of about 5 to 10 degrees.

THIS! In my old townhouse, the entry door to the garage was close to the kitchen so it was great to be able to leave drinks out to chill when guest come over and/or wanting something to cool fast before putting it into the fridge.

New old house has two car garage, but not a stitch of insulation anywhere in the garage, it feels colder inside the garage than outside at times when it's cold out.

13.1 according to my sensor.

Usually around the 10 degree mark when it super cold. Depends on how long umi have the door open and if the two cars have hot engines or not.

It's comfortable enough for me to ONR wash the cars in a sweater on the coldest winter days.

18c in my garage all winter. We live in a tradition 4 level split with the double car garage. THe house is hot water heating and there's one long radiator along the back wall of the garage so it's always toasty in there.. The original doors weren't insulated so I just added styrofoam insulation to them. . I use the garage as a workshop / greenhouse for storing outdoor plants and germinating new ones for the spring. I also keep my motorcycle in there so I can ride it all year if the streets are clear/no salt/ice for the occasional spin.

I felt my garage was extremely cold last year, whatever it was outside was the same inside. All the walls are insulated, but the garage door is a basic wooden one.

My pandemic projects this year included adding draft barriers to the outside of the garage door, window insulation, and styrofoam panels from Lowe’s (supposedly rated at R8). Result (so far) is a 10 degree difference from the outside temps.

I use my garage as a workshop, sandbox area...and fridge occasionally, so I figured it’s worth a shot to try to make it warmer.

My walk-in refrigerator is about the same as outside.
however, when it get really cold in Montreal, it stays a fair bit warmer.

You can see my garage temp drop from 9.6C to 8.6C when I opened the door for a few min to leave.

2-car garage that's part of the house, so about 1/2 the walls and roof have exterior exposure. Door fits reasonably tightly, but there are small gaps and it's not insulated.

Temperature in the garage is about 1/2-way between outdoor and indoor temperature, probably a few degrees more toward outdoor.

im in Edmonton, even on the -35 nights our front attached garage stays above zero, the coldest it gets is 1-2 degrees on those days, most days are 6-7 degrees

insulated walls and insulated garage door.

makes for a great beer fridge for 4-5 months a year.
