That insulation will help a LOT! We're going to double insulate the exterior walls on the addition. SSQ's gonna use 2x6 studs with batt insulation between them. Then he's gonna put 2x3s horizontally on the studs and put strips of insulation between those. I've never seen it done that way, but we'll end up with 9" thick walls that will make the place VEY cozy!
He's still thinking of having someone else float out and sand the drywall or do a skimcoat. Some friends remodeled their family room last year and had the skimcoating done. The walls are just gorgeous! We could do the regular drywall thing, but it's a pain in the behind! He can install the stuff, no problem, but I hate having to do all the sanding between coats of joint compound.
Oh wow! I've never seen it done that way either, but it sure will make the place warm and toasty!
