In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
Thoughts on dense packing plaster walls?
1940's Colonial with plaster and lathe walls, no insulation in walls. We just replaced all of the falling apart single pane windows with Harvey replacements (U factor of .30). Boiler is a Penco NG, probably 20+ years old but seems to work fine, just not very efficient. As part of our attic is finished/heated space, our energy audit recommended spraying open-cell in the rafters first, then if needed pack the walls.
MassSave program offsets $2000 for the walls. What are peoples thoughts on insulating the walls? I've read so many contradictory posts about vapor barriers, settling, rotting sills, etc. Walls are in good shape (at least 1" thick concrete board was found in the kitchen, not sure about the rest of the exterior walls.) Some interior walls have lathe, some have wire mesh. Aluminum siding over wood. Just trying to get some input on if it makes sense to do the dense pack right away, or wait and maybe put that money towards a new boiler.
Thanks in advance, just trying to tighten up this home as much as we can!
