Sorta off topic, but it's for my RV shop...
I'm getting ready to insulate the shop. The ceiling has 2x8 joists, so 7 1/2" of space. Is it better to get the 6" insulation bats and almost fill the space, or to get 9+ inch bats and cram it in?
I have not been able to get a consistent answer. Some say even though the thicker stuff is crammed in I will get a little more R value out of it. Others say cramming it in is a bad idea. I'm going to drywall over the insulation, and ventilation is not an issue as it is an old building and the floor above (attic) is 1x6 boards.
Any thoughts?
Thanks
