looking to insulate our walls, they have no insulation, except in the addition. Have already insulated the attic.
What we notice is on hot days, the south inside wall of the house (house is stucco) stays warm well past sundown, and the AC runs because (we think) the stucco is radiating heat into the house (and to the outside). So insulating the wall will slow/stop that heat infiltration. It should also help in the winter time to keep the house a bit warmer, though the attic insulation is going to do most of that.
contacted one company, they come drill 3" holes in the sheetrock and blow in fiberglass to the tune of about $3k. Either I patch the holes, or they have a drywall company that will come patch them...for more $$...the sales guy said the drywall work is often as much if not more than their cost. so on the order of $6k, not sure its worth it for that much.
reading a bit on the web, and it sounds like dense packed cellulose it a better option for blowing in walls.
So I was thinking...
finding stud bays, easy enough
drilling 3" holes, easy enough
renting the machine and buying the insulation, easy enough...if you buy enough insulation, they don't charge you for the machine.
blowing in the cellulose, well from watching videos, that doesn't look too hard, though messy....but who knows never done it.
patching the holes, I have a retired contractor that knows how to do that. (which he could also do if we paid the company...)
anyone done this for their house?
other suggestions?
