Insulating a small old farm cottage
Part of the property I'm looking at is a small, old farm cottage, built in the early 1900s. We just did the house inspection today, and there's NO insulation in any of the walls, or the ceiling.
It'll be a rental, so I don't want to pay for foam, or removing siding/plasterboard but if there's something fairly easy and cost effective, I think it should get done.
The ceiling looks easy enough to fix, the attic is pretty accessible and either fiberglass batts or blown in cellulose or whatever looks like it'd work.
The walls are what I'm wondering about. It looks like balloon framing from what I can see, so my first thought was just to blow in something from the top and have it settle down. However ... it looks like there's no vapor barrier, and one can see little chinks of light between the clapboard siding when looking from the inside of the endcap attic wall.
Presumably cellulose would go moldy? Is something like fiberglass OK, or is that a recipe for disaster too? It doesn't look damp in there, but at the very least, it'll get damp summer air in there (NW New Jersey).
I guess the ceiling (and all the single pane windows with air gaps) are the biggest issue, but if there's a fairly cheap and easy fix for the walls, it seems like I should fix them.
