Spray Green Foam in Thermo Ply Walls

I used Foam It Green #102.  It covered the walls well and did not over spray. I really protected the beautiful ceiling with plastic drop cloths attached with double sided tape. It was easy to apply but the price was expensive.  After finishing, I realized the thermal ply is flexible and it may have been better to use open cell foam.  I used closed cell so the wall has more rigidity but believe using 1" insulation, cut to fit, would have been just fine. I used the Dremel to trim the excess foam.

Now the walls are insulated, I can install the windows on the long walls and start putting up the interior T&G.
