Ive got a two story house with a 20x20 garage on one side. The garage wall
which is the side of the house is insulated I'm sure but the other two exterior
walls are not drywalled or insulated either. The garage door is some
metal/plastic composite or whatever they use these days. The ceiling is closed
in with drywall. (I heard building codes require that now) When I went through
the acess hole into the garage ceiling, I noticed there is no insulation up
there. Is it worthwhile to do so? My wife thinks not because the garage is not
heated. I do not plan to insulate the 2 exterior garage walls because Ive got
shelves up and have nailed some things to the studs. If it is a good idea
though, I might do it. Opinions?
Do you plan on useing the garage for hobbies? Woodworking, tinkering on
cars? If so, then insulate the walls and ceiling, and paint it all semi
gloss white. It really does not cost that much. Insulation will even out the
temps quite a bit. It won't be soo hot in the summer and cold in the winter.
The white paint will briten it up allot.
Next step, add heat and air conditioning!
As long as the house is insulated from the garage, you're doing all you can to
save heat. The garage ceiling isan;'t insulated, even if it is the same attic
as the rest of the house, because there's no heat in the garage you'd want to
stop loss into the attic.
If it gets down to 10-20 degrees and you don't care about
stuff in the garage freezing or getting into a relatively
warm car in the morning, or aren't ever going to do anything
in the garage except get in and out of your care, forget
it. If you care about any of that, insulate it. A fully
insulated garage will keep your house warmer, but the
payback for insulating it will be very long. I would
insulate the walls, add drywall, and put 3-1/2" thick batts
in the ceiling. Not expensive and would improve the looks
even if you don't tape and mud the drywall.
