I wish the rest of the house was done already.
It does seem to be working. That wall was pretty horrible to begin with, and with such a large step forward I did notice a reduction in my gas usage.
The windows are great... if you have the money. You can touch them and they don't even feel cold. I did get the higher SHGC mainly because the VT (visible transmittance, aka how much light gets through) was higher, and the whole reason I put the windows in was to get light into the room.
I actually just worked on the room this past weekend for the first time in ages. It now has drywall up over the concrete board.
