Owners of this warehouse came to us for a second opinion after they received a quote for spray foam.  They were also led to believe that spray foam was the only way the building would be able to be comfortable.  I explained how we could fit full R-38 insulation in their 2×8 roof joists with the aid of black scrim facing.  This doubled as a solution for how to make the building look better, where as spray foam would have been unpleasant to look at.  The finished project looked beautiful, came in way under budget and made a very comfortable space that does not take a fortune to heat or cool.
