I'm looking to do a weathered wood interior wall surface in my garage. Currently, this detached garage has old, nasty pink insulation between exposed studs, in front of wooden plank exterior walls.
Questions I have:
- Before I put in fresh insulation (after removing the old), should I seal the outer wall with anything?
- After I put in new insulation, should I put anything between that and my weathered wood?
Note: This is in Minnesota, where the winter gets cold and dry... and the summers are hot and humid.
Why? Why put up ANY interior finish?
Or insulation for that matter...
Do you live in your garage?
Are you spending a lot of time in there?
Good questions.
We have a two-stall garage, and we're a single car family. The other stall will absolutely be a place we spend time doing home improvement projects, woodworking, etc. Insulation will give us that extra edge as the months get colder. We do have gas access, so we could heat the garage for year round use, and insulation would hold in some heat. The interior finish would just improve the looks.
Yes many people in MN insulate their garages. It is very helpful considering the many many months of inclement weather we have here. The finishing helps with the dark winters as well. My last garage was insulated and I am going to insulate the one I have now too.
My garage has the same look as the one in the photo of the OP. Does anyone know if those ceiling trusses can hold sheetrock without damaging the roof? They must be the same ones used in the rest of the house, right? But the span seems so much larger without any supporting walls or posts. Mine is double garage with an extra area for a room at the back of the garage. But I don't want to add a wall.

What is "wooden plank exterior"?
Is it lap board or T&G?
Whichever it is I'm going to burst your bubble...
The problem will be making the wall air-tight- lap board is no where near air-tight. T&G can be somewhat. Batt insulation needs to be in a dead airspace to work at peak performance; otherwise your wasting money with the insulation. Trying a haphazard sealing with caulk, foam board, plastic, whatever is again a waste of money and time.
The only insulation that will both work at peak performance AND completely stop air leakage is Icynene foam. Once it's installed you can install whatever wall covering on the walls. However, keep on thing in mind. Even though the garage is a detached building why add more flammable material to the building considering its use? I strongly recommend using drywall for nothing more than its RESISTANCE to fire. If you're concerned about the walls getting beat up just add plywood/OSB on the bottom- like a wainscoate- over the drywall.

I haven't looked really close, but the photo above shows some looking through the missing insulation. I think it is just horizontal planks, top to bottom, with cedar siding on the outside of that.

The attic can just be blown with loose-fill.
I haven't made any moves on this project, so I'm open to most alternatives.
As is, the garage is 40 or more years old, with almost nothing done to stop air leakage. I'm shooting for "something" rather than "almost nothing."
What do you mean by "more flammable material" ? The weathered wood wall covering I mentioned?
There is no attic.
