I'm note sure but I added about 2x the amount that was in my house attic when I moved I bought the house. Later on I reinsulated the house attic and did blown in insulation. Not one single icicle afterwards.
Sorry for my Brain Fart...R-30 sounds very familiar. That's probably what I used. That was three children and one house ago! Whatever it was it was sufficient for Michigan winter and I always tend to overdue what it is I'm doing. : )
I am 100% on board with the vapor barrier. I just wasn't sure if I needed to do something additional if I use R-19 batts that have the vapor barrier attached as part of the paper face. I would prefer batts over blown-in just in case I need to remove panels later for modifications.
I wasn't sure if shifts in temperature and humidity would cause condensation to form on the topside of the metal...especially if I heat the garage in the winter.
Based on responses here it seems there is valid concern about the weight of OSB. If I went with metal panels, what do I do for a vapor barrier? Can I still install the 24" wide R-19 batts with the vapor barrier or will that trap condensation between the topside of the metal panels and the...
At my last house, just like this one, when we moved in the garage was bare studs. I insulated the walls with R-13 fiberglass and the ceiling with R-19 (R-19 if I recall...it was much thicker than the R-13 I used on the walls) fiberglass. Both of them had a vapor barrier. I was happy with how...
That's a funny story and I'm glad no one got (seriously) hurt. Good point on not being grounded...maybe that's enough reason to get rid of it. I looked at some of the online catalogs on the above link provided by RTM and it looks like back in the day one could buy a drill press frame to make a...
Once insulated and my hanging furnace installed, I'm hoping to keep the interior temp slightly above freezing so the cars thaw during the winter. I have a new sloped floor with a drain so the water shouldn't collect in one spot. I also plan on priming and painting the OSB. I could use...
A friend of mine is an electrician and has wired many garages with the corrugated metal ceiling. He said he punches through the metal and makes the connection inside the light. I'm concerned about the holes in the metal cutting through the wire insulation so he must have used some type of...
I had the same thoughts regarding the "paint" but I think it is glue. I definitely plan on insulating the walls and ceiling. I was probably going to staple in R-30 batts.
A friend at my church sells and installs the metal panels and I actually gave some thought to going that route but I was hung up on how to mount receptacle boxes (you're saying one will fit between the ribs) and also OSB or plywood would give me the flexibility to screw things to the ceiling if...
Attached are three pictures of the trusses inside my 1970's garage. I'm currently working on wiring it and soon will be installing a ceiling. Can anyone tell me whether or not these trusses will support 7/16 OSB? I need to determine my intended ceiling thickness before installing receptacle...
