Comfenergy Before & After Photos

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.

This Amissville, VA homeowner was looking to lower their utility bills this coming winter.  This before and after pic shows how we removed/disposed of the old fiberglass batt insulation.  Then, newly blown TruSoft cellulose insulation was installed. This cellulose insulation is more densely packed and does a better job at insulating a home than fiberglass due to its quality and ability to reach a high R-value.

HVAC ducts likes this one in the attic of this Harpers Ferry WV are designed to deliver conditioned air (heated or cooled) from the HVAC system into the rooms of the home below.  In the summer attic temperatures and reach up to 120 degrees or higher and in the winter attic temperatures can fall well below freezing.  That means the conditioned air could be travelling through a duct that is either baking in the heat or has been sitting in freezing cold temperatures as if it were outside.  These harsh conditions can work against the efforts of the HVAC system and result in the conditioned air being less cool or hot than it needs to be to make the rooms of the home comfortable.  It also causes the HVAC system to run more than it should, running up energy bills.  Encapsulating the ducts in spray foam helps insulate them from being impacted by external temperatures.
