During the winter of 2008, Combat Coatings®, LLC was approached to provide spray foam insulation in the roof deck of a new medical research facility located at 1851 Old Donation Parkway in Virginia Beach.  The foam insulation had to fill two important roles: First, it had to act as an excellent thermal barrier; secondly, it was imperative that it negate the noise of low-flying, Navy “Hornet” jets from nearby Oceana Air Base.  The consulting architect on the project had originally called for standard two pound density wall foam.  If you read my letter to the contractor dated 15 February 2008, you will note in paragraph # 3 that our recommendation was to use “open cell” or half pound density foam insulation due to the superior STC rating and Sound Absorption Rating.  We have attached independent test results that validate our recommendation.  Both architect and contractor evidentially agreed to use the “open cell” foam that we recommended and the project is now two thirds complete.  With oil trading at $115.00 per barrel, we know that the R value of 39 in the roof deck will provide lower energy consumption for decades to come; and, the live-in patients at this new research facility will enjoy an environment free from the impact of noise from the local air base.
