There is a pretty large detached garage on my property (built ca 1995) approx 16' x 29'. Previous owner had started putting R-11 insulation on the walls and underside of roof, but I think may want to take a different approach. Am looking for suggestions.
My goal would be to put in some sort of heating (Northwest Ohio) so that I can use this for woodworking throughout the year. My question is aimed at construction and insulation.
See attached photos. He put fiberglass insulation directly against the underside of the roof. I'm not sure this is good practice, especially if a ceiling is installed.
The roof appears to have a 2x4 ridge and rafters, and 2x6 joists--all spaced 16"oc. There's also an L-beam made of 2x6s (I don't know what this is) that run the length of the shed with vertical posts attached every 4'.
Will this construction hold an OSB ceiling + insulation? Any other suggestions on ceilings?
If I put in a ceiling, should I remove the insulation that's against the roof?
The soffits are vented but there are no other vents on the roof or attic area. Should vent/s be installed?
The garage is on a concrete slab.
Thanks for any advice or suggestions!
