About the time I get to the back door I'm looking at this and thinking maybe I don't want to install anything on the face of the framing after taping the insulation...
It's very reflective and actually brightens everything up a lot...
I used the sheets laying down in a full 4' x 10' length and installed the first one on a Z furring channel at the floor and the second sheet against the bottom of the steel beams. This created a chase in the wall that allowed for the PVC pipe for electrical to be installed in.
Once insulated and taped it is the finished product.
