The winter has finally come and nobody wants to work in a cold shop. I got a heater, but it only seems to be able to maintain a temp about 20 degrees above ambient. I’m a little worried that once it gets down to say 0 that the garage will never get above freezing. Instead of getting a bigger heater I would like to keep the heat I am putting out.
The garage is a two car, but is divided down the center with a stud and plywood wall. It is a rental so someone else has that stall and is unheated. The walls are brick and uninsulated. The garage door is crap. The garage roof has a 8’ peak. I put plywood and stairs in for storage, so it is a triangle type area.
So my question is where should I put my efforts to retain the heat. I could insulate the joists between the attic and ground floor. It seems that a lot of the heat just heats that area. Or I could insulate the roof, although it doesn’t keep the heat where I want it. I also plan on putting some rigid foam on the garage door. Insulating the walls won’t happen since I already have shelves and such mounted to them.
So if I insulate the roof or ceiling, does it matter what type. Can I use unfaced fiberglass or should I use faced. The only advantage I see is the resistance to dust. I’m not too worried about moisture because I only plan on being here for 2 years and I will probably tear it out when I leave. Or could I use rigid insulation between the joists.
I also want it to be as cheap as possible because it is a rental and I will really only get two winters out of it. Any input would be appreciated.
