Spray Foam Insulation Before & After Photos

This wise homeowner in Herndon, VA chose to use closed cell spray foam insulation in the walls of their new home. This is a wise investment for comfort and efficiency.  Closed cell spray foam not only insulates better than fiberglass batts, it creates a great vapor barrier on the exterior walls.

The finished side of this space on the other side of this attic wall is some ones room.  Uninsulated, it was being impacted by the temperatures in the otherwise uncontrolled attic.  This would lead to that room being too hot in the summer and too cold in the winter.  After applying spray foam insulation and then air sealing and insulating the rest of the attic space, there would no longer be an impact on the living areas and bedrooms caused by the attic temperatures. 

Part of this Herndon VA attic project included spray foam insulating the HVAC ducts running through the space.  Attic temperatures can fluctuate heavily depending on the season.  In the hotter months of the year, cold air trying to be delivered through HVAC ducts can be impacted by the hot temperatures in the attic.  In the colder months of the year, hot air can have the same effect from a cold attic.  This can all cause the HVAC system in a home to run more often than it should and raise energy costs.  Insulating these ducts with spray foam protects the air inside and reduces the amount of time the HVAC system has to run.  

This Reston VA home had an attic that was not properly insulated and causing comfort issues in the home.  A lack of an air seal for the attic was allowing conditioned air from the rooms in the home to leak away.  Walls in the attic that were covered with traditional bat insulation were not holding temperature and had cracks where more air was escaping.  Our production team removed the existing insulation from the attic, used Zyp Foam to air seal all of the gaps and cracks where air had been able to escape and then used Spray Foam to insulate and seal the walls.  Tru Soft cellulose insulation was then blown in to cover the rest of the attic floor/surface.  

This Great Falls, VA homeonwer was actually a repeat customer.  They were so impressed with what spray foam insulation had done in other areas of their home, that they asked for more now in other areas.
