Save Energy - Convert 4" Walls to 6"

Converted 4" exterior wall to 6" wall by removing drywall, adding furring strips, insulation, and new drywall. Since our old insulation was matted down, this renovation could effectively double our R-value and the several hundred dollars spent could be recovered in a season or two.

I very much doubt that someone is going to devalue my home by $2400 because of the lost 2" on the exterior and if so it would be offset by the fact that we have 6" walls instead of 4" (it gets to -30F here!) . The R-value upgrade was nearly double for us - 3.5" of matted down outdated rockwool vs. 5.5" of new fiberglass. And in the header area I added 2" of dense foam instead of 3.5" of wood - more than double the R-value. We feel the difference in our bedrooms!

You/This guy didn't SEAL vapor barrier.So water vapor,created in the home wil enter the wall cavity,condence into water&damage wood framing ovr time,not to mention mold growth. This house will not last 100 years.

I have personally seen the effects of this common, un thought out building practice.

Now you/his/her&or realtor wil want to list this house for some stupid price on this rotting, unhealthy box.

Damb! I'm gonna have to start doin videos. What does it take for people to wake up???

You will never save the cost of the remodel here with energy savings. Insulated wall makes up about 5-10% of your envelope. Beef up that 5-10% all you want, it wont do much to save any energy. That is why they dont do it in new construction. That and the fact you may lose 20+ sqft of living space, avg house is 120$/sqft, which means you just lost at the very least 2400$ worth of home by doing all of the outside walls.
