Spray Foam Insulation Before & After Photos

Sometimes comfort and energy issues can be caused by leaky and poorly insulated HVAC ducting.  The before/after pics that follow show a duct that was poorly insulated, running through a cold attic in the winter.  Hot air was leaking into the attic instead of going to the room to deliver the hot air.  Plus there was little to no insulation on it which was "cooling down" the heated air making it less efficient.

Comfenergy sealed the ducting and insulated it with an R13, closed cell spray foam.  This seals the duct leakage and insulates it to better than the existing code (R8)

This home in Charles Town WV was designed with several cantilevers.  A cantilever ("a long projecting beam or girder fixed at only one end") is part of the home that hangs out from the walls of the home.  The cantilevers of this home were uninsulated and therefore allowed the outside temperature to impact the air and comfort of the inside rooms connected.  Our Home Performance Sales Pro Greg determined that the use of spray foam to insulate the cantilever would help solve this problem.  The lower cover of the cantilever was removed by our production crew and then spray foam was used to fill in the hollow space inside.  

Homeowners in Boston, Va have a farm and wanted to insulate the walls in their barn. One of our evaluators, Pedro, determined that closed cell spray foam would do the best job at insulating this space. Closed cell spray foam adheres to all surfaces, expands in place, and air cannot pass through it. It has an R value of 6.3 per inch and with it's ability to stop air flow, it is superior insulation. One inch of closed cell foam sprayed in place is worth many inches of other insulation materials. This is why spray foam is used in most "zero energy" homes. 

This crawl space in Delaplane, VA was encapsulated using closed cell spray foam.  This was done to make the floors above the crawl space warmer in the winter.
