There were severs drafts coming through the knee-walls of this Alexandria, VA home. Comfenergy used closed cell spray foam to air seal and insulate them to stop these drafts. 

Closed cell spray foam was used to insulate the exterior walls of this basement remodeling project in Alexandria, VA.

Protecting conditioned, heated or cooled air, from an HVAC system can help lower energy costs.  As air passes through the metal duct system it can react to room temperatures where the ducts are.  A cold room with a metal duct can cool heated air moving through it, just as a hot attic with a duct in it can impact the cold air passing through it.  Encapsulating HVAC ducts with spray foam keeps the environment inside of the duct safe for conditioned air to travel through.
