    Insulating 1940s wood garage in Maryland - Rockwool and closed cell foam?

    Alright! Bumping an older thread as I just pulled the trigger and I couldn't be happier. One other really nice upside is that the white foam also makes the whole space seem much brighter and cleaner! $2,900 all in.

    Yeah the current roof is unvented, but it's also an old wooden building, so I'm wondering if some degree of breathability is preferable. I'll report back once I hear from the other companies.

    First quote today and interestingly he was suggesting open cell foam to let the roof deck breathe better and also prevent moisture build up. He thought I could get to R20 with 5.5" of open cell. Next contractor couldn't come out until Jan 14, so will report back once I hear from him.

    Yes you're right, it is probably closer to 16' high. The cross beams are around 8.5' high and that's about half the total height.

    Thanks very much Colin. That's really helpful. Your finished product looks great. I agree on Rockwool being pretty durable for me too, I think some sheets got a bit squished in transit, and they were a bit more breakable, but you can kind of just push offcuts in to offset any breakages. I'm...

    Not that I can tell - the roof has an uninterrupted ridgeline. I'm guessing they were keeping things pretty simple construction-wise for garages in 1942!

    I don't want a ceiling as I want to retain the full height - the current rafter placement and height is perfect for what I want and need for both golf simulator and weight lifting. The project will mainly stretch over a longer period because I'm focused on getting to a more insulated conditioned...

    Insulating 1940s wood garage in Maryland - Rockwool and closed cell foam?

    I spent a bit more time looking at the venting situation this morning, and I actually think the current setup is completely unvented - I thought there was a gap between the wall and roofline at the soffit to allow air flow, but it's actually just a crack (probably from the wood contracting and...

    Thanks to everybody who has replied so far! I think I'm going to go Rockwool for the walls, primarily as it's relatively cheap and will hopefully take the edge off a little bit in winter (I know most heat is lost through the ceiling but that may need to wait until the new year from a project...

    Hi all, Long time reader, first time caller. We recently moved into a house in central Maryland, and the garage is going to be a multiyear project. Longer term goal is to turn it into an indoor gym while retaining parking. I got a 14,000 BTU window AC for summer, which made it liveable...
