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.

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.  

This Harpers Ferry WVA home has an enclosed room/deck area that was too cold in the winters and too hot in the summers.  The homeowners called to see if we could help make it more comfortable.  After performing a Home Performance Inspection, our Sales Pro Jonathan was able to identify a need for better insulation below the room.  The existing batt, rolled insulation was falling loose from the flooring and had gaps where the hot and cold air from outside was able to move into the floor above. Jonathan recommended the use of spray foam to air seal and insulate the spaces between the frame for the deck/floor.  This will keep the space more comfortable and reduce the energy cost to heat or cool the room.
