If anybody has any experience in installing insulation in exterior walls, I could use a little help.
I am having new siding put on next week and want to add insulation where there isn't any currently. I am going to pull the old siding off, put the insulation in the wall cavity, and then put 7/16" OSB sheathing on top of that. Then the contractor is going to install that foamboard on top of the OSB before the siding.
Since the old siding is in bad shape, I want it gone anyway. But the interior walls are newly painted and I don't want to (rather, I won't) pull down the sheetrock.
So, my question is this: I have read online that, generally, the paper side of the insulation should be attached to the inside (house interior side) of the studs with the fiberglass/pink side facing the exterior. That is, unless you live in an hot coastal climate (which I definitely do), in which case the paper side should be on the outside of the house with the fiberglass/pink side adjacent to the back side of the sheetrock. Bottom line: Two different stories have me concerned -- and I'm not even sure the paper qualifies as a "vapor barrier" (it appears to only be plain brown paper). I am using Owens-Corning R-13 for the south wall (which was free courtesy of my neighbor who didn't need it), and will use something stronger for the west wall that takes the real beating from June-October.
I attached a drawing to show what I mean (the colors are for clarification only).
Please tell me "A" is correct (but don't lie to make me feel better), and if it happens that "B" is right, is there any way to attach the paper flange to the inside (interior side) without pulling off the sheetrock?
Thanks in advance.
