Garage/workshop too cold

veronica732January 8, 2010

I have an attatched garage with insulated walls. The ceiling is drywalled but has no insulation. I want to work in the garage but it is way too cold. The snow will not melt from my car. Anyhow, if I insulate with rolled batting how much of a difference will there be? I was originally going to put down R-38. Then I thought I should put 2 layers of R-30 criss-crossed to give me R-60.

Am I going to gain any more warmth by R-60 over the R-38??

You won't gain much if you don't heat it. What do you plan to use for a heat source?

My fully insulated attached garage is ~20f warmer than the outside temp when its really cold (zero or less). Its unheated.

If the temperature stayed below zero, the garage would fall to below zero too.

Insulation dampens the interior temperature swings. More insulation increases the damping factor, but without a heating and/or cooling source any closed structure will be too cold or hot to work in comfortably unless it is located in a very mild climate.
