I can tell that the spray insulation did an amazing job. I would have never thought it would be so efficient at cutting heat!! My friend's large garage has a concrete foundation and at night the cool off the ground soaks into the building so that the interior is cool in the morning, even on those super hot days the building is cool in the morning until about 11 AM then he turns the AC "on". This is typical for 95 to 100 degree days most of the summer. He just sent me a text......$3500 for 1500 sq feet of walls and ceiling (it's a large garage). That's about $2.33 per sq ft.?
