Brand new here. 1st post. So I'm getting close to completeing a long project of building a 30'x42' detached garage that I intend to heat. 45 degrees most of the time and a little warmer when I'm working. I plan to be here another 40yrs or better so I want it as efficient as possible with no problems down the road. I'm in the north part of zone 4. Should I use open or closed cell foam in the walls? Benefits and potential problems with either?
The bitterness of low quality will remain long after the sweetness of low cost is forgotten.
