Stallion Motorsports1647545491 Posted April 16, 2014 Report Share Posted April 16, 2014 Really quick background, I'm starting a weekend project this week in our living room. The room has two exterior walls, and a wall that is against our garage, it is also above our non-heated crawl space. I'm drywalling the walls, but would like to insulate first including the garage wall. What insulation should I be using? R value? Brand? What has everyone used and liked lately? Thanks, Tom Quote Link to comment Share on other sites More sharing options...

Thanks, Tom Owens Corning R-13 or really any brand will do. If you're insulating exterior walls, you need to have a vapor barrier between the insulation and drywall to help with moisture. You can use a kraft faced insulation with the paper facing the inside of the room. Unfaced insulation and a 4mil visqueen used as a vapor barrier is typically cheaper than using a kraft faced insulation. If you decide to insulate the crawl space, the vapor barrier is typically done a little differently. I would use an unfaced insulation in the floor joist, held up with a twine. I would lay a layer of 6 or 8mil visqueen on the ground. Hope this helps. Quote Link to comment Share on other sites More sharing options...
bmwohio Posted April 16, 2014 Report Share Posted April 16, 2014 I just finished my basement a couple of months ago and used the Owens Corning EcoTouch R-13....supposedly you can touch this stuff with your hands and it won't irritate your skin (however, I wore gloves anyway). It was just a friction fit, and the warmth in the basement is fantastic with this stuff. Quote Link to comment Share on other sites More sharing options...
Trouble Maker Posted April 16, 2014 Report Share Posted April 16, 2014 Why wouldn't you staple it in? Quote Link to comment Share on other sites More sharing options...
WrxRcr Posted April 16, 2014 Report Share Posted April 16, 2014 Wouldn't stapling reduce the effective R value? Quote Link to comment Share on other sites More sharing options...
Sully Posted April 16, 2014 Report Share Posted April 16, 2014 Wouldn't stapling reduce the effective R value? LoL. No. You staple the flaps on the side to the 2x4's. If you don't, the insulation could slide down the wall over time. Quote Link to comment Share on other sites More sharing options...
bmwohio Posted April 16, 2014 Report Share Posted April 16, 2014 Yes, it was a friction fit and then you fold the flaps over and staple it to the framing. I had not folded the flap and stapled at this point in the picture. Quote Link to comment Share on other sites More sharing options...
