Default Sealing the basement (continued)

I picked up a 4" x 8" sheet of 2" rigid blue foam board and a can of Touch N' Foam minimal expanding spray foam from my local small-town lumber yard for about $42.

My foam cutting skills leave much to be desired, but I managed to get the insert to fit with about a 1/4" gap all around. I later found that I should have left closer to 1/2" for the foam to fill.

Freshly foamed. It's not pretty, but it's effective . This stuff takes about 4 hours to fully harden and expand, so I'm curious what it's going to look like in the morning.

Finished with window #2. This one came out a little better. The boards are holding the insert in place while the spray foam hardens, as it tends to try to fall out of the window. That glass block storm window is pretty well sealed on the outside and around the frame, so I didn't try to remove it, but there isn't enough room between it and the inner window for the 2" foam. So I just removed the inner window. I actually ran out of foam around the outside of the window frame, so I'll have to get another can and finish up the cracks. *If you look closely, you can see the R-value chart on that piece. I circled the 2" to remind me every time I look at it that I have R-10 in that spot. *

I think I was getting that hang of it by the third window.

Next is to finish foaming around the window frames and trim off the excess. Then I'll seal up the exterior of the windows. I have yet to decide if I'm going to silicone the outer storm windows shut or just weatherstrip them. I'm also wondering if I should paint the glass a certain color (black maybe?) before sealing them up. Any suggestions?

More to come, stay tuned!
