Presumably, you are entirely removing interior plaster&lathe/drywall to access wall cavity (and replace wires) rather than drill holes and blowing insulation?

- Freak_NL 4y agoIf you are upgrading the insulation from the inside you'll have whatever is the inner wall out anyway, it's pointless otherwise; if you're doing it from the outside (possible with some roofs) it doesn't matter; and filling the wall cavity is done from the outside too, unless you have a really weird house no wiring goes there.
- PaulDavisThe1st 4y ago> If you are upgrading the insulation from the inside you'll have whatever is the inner wall out anyway In Philadelphia in 1996, I had a company blow in insulation to my wood-framed, plaster+wood-lathe covered cavity walls without removing the inner walls. They created a series of 4"/10cm holes at the top of each bay and blew the insulation in that way. ps. I later found out that this is a terrible idea for vapor control reasons.
- Freak_NL 4y agoYeah, that's basically why just putting up new walls is the long term solution. And as a bonus you can put in some sweet CAT6 cabling and enough electrical sockets while you're at it. :) Another benefit: when you take out the inner walls in an old house, you are going to find layers and layers of… stuff. Like 2cm of styrofoam (insulation in a nineties way) and a new layer of drywall on top of whatever chipboard/grout/newspapers where put in in a distant past (at least in my old house).
- germinalphrase 4y agoMassive project though.
- drjasonharrison 4y agoYou don't have to remove all of the lathe and plaster. Blown in insulation after upgrading the electrical. Fish poles and long cuts repaired afterwards.
