This is what our son Michael and I managed to get done this evening. We're going with a two inch thick Foamular rigid foam insulation, and 2x4 framing and drywall in front of it. When we're done well have a combined insulation rating of R12.55. That's a combination of the R10 for the rigid foam,
R1.11 for the cinder blocks, R1 for the air space, and R0.45 for the drywall. All of the joints are taped with Tyvek tape, and we'll be laying a bead of low expansion foam insulation along the bottom of the rigid foam to fill any gap by the floor.
Next we'll be starting on the framing. Once that's up, we'll move the home gym over to this area and start the whole process again. Two more areas to go after that, then we'll take care of plumbing, electrical, and drywall. This is going to take a while, folks!
But it'll be so great when it's done!
ReplyDeleteI have been watching remodeling shows for years and never saw it done this way....don't you frame first? Run electric then insulate?? (albeit I'm no pro when it comes to this stuff). Regardless - the insulation wall does look perfectly done....
ReplyDeleteThe benefit of doing it this way is that the foam insulates and acts as a vapor barrier simultaneously. It also keeps the framing away from the foundation wall. I had considered going with spray foam insulation, but this was far less costly to obtain the same R value. This was also one of two methods detailed in Mike Holmes's basement book, the other being spray foam.
ReplyDeletelooks great - can't wait to see the updates and the progress. So ya got Mike Holmes's book huh...the man does seem to know his business. I bet you guys are gonna do a great job...keep us posted :) be careful around that electrical!
ReplyDeleteHaving never done this I bought a few reference books to study up. His books gave some very good tips. Idiot's Guide To Basic Framing was the most valuable for this part of the project. It cleared up all questions I had.
