Concrete has a lot of thermal mass, so in the winter if you don’t constantly heat the shop you will be fighting that. In the somewhat limited use my shop gets in the winter my feet are always cold due to the concrete floor.

Even if you do heat it constantly it will still hep transfer the cold from the ground and make your heating a little harder.

Bungy, it would help to insulate the floor but it really depends on where you are located as to whether it will be cost effective or not. For instance here in Kentucky I can keep my shop comfortable with a 1500W space heater during winter and do not noticeably feel chilled by my uninsulated concrete floor. The normal ambient temperature is generally above 20 degrees Fahrenheit during the winter and I have about 350 sq feet to heat.

But adding a wood floor over the concrete would make it easier to work on.

Bungy, I have a pole barn with a concrete floor, and yes the floor gets cold. If I built it or were to build one I would go with tubes in the concrete for radiant heating. The heat rises, everything is comfortable and the only thing that is needed is a hot water heater.

Thay being said, any insulation on the floor will help, even rubber mats. If you can build a subfloor I would do it because there are other advantages to one also. Besides insulating you can place DC piping there and put wire chases in it so that you don’t need to run extension cords everywhere.

Good Luck.

If you have a metal roof you will need to insulate it next to the metal or it will rain in your storage loft.

Yes … insulate the floor.
