Comfenergy Before & After Photos

Dumfries VA homeowner wanted spray foam insulation in their attic area.

Here is a before/after of a light fixture being air sealed in the attic of a home in Dumfries, VA.

An unprotected HVAC duct system can leave you with an uncomfortable home and higher energy bills than you should have.  Conditioned air, heated or cooled by the HVAC system is intended to pass through HVAC ducts to get to the different rooms in a home.  If the temperature in an attic is 125 degrees in the summer, the cold air trying to move through the HVAC duct is in a hostile environment.  Same idea in the winter.  If it is 25 degrees in an attic, the 74 degree heated air trying to pass through the HVAC ducts is fighting to stay warm.  Insulating ducts with spray foam helps protect that air and eliminates air leakage at joints and turns in the duct system.  The insulation wrap that had been used to try and protect this duct systems was eaten through by rodents and had multiple holes and tears.  

This homeowner was finishing their basement and wanted to make sure that during the construction process he did something to better control the humidity in his basement.

Closed cell spray foam was the answer that Comfenergy provided.

Part of this attic project in Vienna VA included wrap insulating this Chimney pipe with a rock wool sleeve. This helps keep the heat being exhausted through the chimney from getting into the attic and reduces the potential for fire hazard.  The existing insulation was removed before the attic was air sealed.  The chimney was then wrapped before new insulation was later blown into the attic.
