We converted the attic space in this older home in Alexandria, VA. to a conditioned space.  The customer raved about how much cooler his 2nd floor remained after our work was completed.  The use of Spray Foam made the most sense in this application as there were numerous air leaks and it was difficult to get material into the space.  Spray Foam is a great solution for many of the older homes in Alexandria, increasing comfort and decreasing utility bills.  Spray foam in this Alexandria home also lead to a substantial increase in the amount of usable space for climate controlled storage.
