If anybody is looking for spray foam insulation give Georgia Spray Foam Services a call. They came out this week and insulated my shop. They did a great job, every thing is neat and clean. Showed up on time and did a very professional job. They sprayed the walls and the ceiling with one inch of closed foam insulation. With the sun on the roof at 2:00, it dropped the inside temperature on the ceiling by 18 degrees, between the sprayed and unsprayed area.
