Foam Insulation / Firring Strips

I had four of my Amish friends come over today to put up the 1.5" insulation sheets, and they got that entire job done (in the living area of the house).  We also put a few of the firring strips up just to see how it is going to work...  They snapped chalk lines on the insulation so we can find the trusses easier.

While they were working on the insulation, I was working on getting the strips cut to length for each room, and drilling holes into the ends (so they won't crack).  We were able to put screws through the centers of the strips without them cracking which is great since it saves a lot of time.

Here are some pictures of the insulation and the strips...
