Comment on How would you fill these gaps?
Hazdaz@lemmy.world 1 year agoYeah definitely use a flanged cover plate but if this goes to an exterior wall, hit the hole with some expanding foam first. Let it dry and then cut the foam flush. Then use the flanged cover.

It’s from a garage to an interior wall. I’m not sure if that would qualify as exterior or not.

I consider “exterior” to mean one side of the wall is air conditioned/heated, and the other side is not. Therefore, an exterior wall has insulation in it. An interior wall is generally hollow.

I’d use some expanding foam if you could feel the air from the other side or see through it. You could also fill that area with silicone (which could also be used to help hold the flanged cover too.
