Spray Foam Insulation Before & After Photos

This Fairfax VA attic wall didn't stand a chance against outside temperatures without any insulation.  Spray foam was used to fill in between the framing to create a better air seal and insulate the attic space from the outside temperatures on the other side of the wall.  

The homeowner of this Fairfax Station historic home was looking for a way to lower their utility bills. The Comfenergy comfort and energy consultant provided a great solution that would lower utility bills all year round, and provide a great storage space in the attic!!  

Most attic insulation projects have several steps in the service to improve their performance.  Removal of old insulation, air sealing and new insulation installation are some of the most common options as was the case with this Fairfax Station home.  An often added step to promote even better performance is to encapsulate the HVAC ducts in an attic with spray foam.  Metal HVAC ducts running through a hot attic in the summer or a cold attic in the winter can have trouble effectively delivering heated or cooled air created by the HVAC system.  Spray Foam insulation protects the conditioned air by keeping the ducts from allowing attic temperatures to have an impact.  

This Dumfries VA home had condensation along the HVAC ducts (duct sweating) due to external heat making its way into the home via uninsulated rim joists on the side of the house.  Hot air from outside was working against the cold air moving through the HVAC ducts and causing the duct sweating which was showing itself as water spots on the basement ceiling drywall and mold.  Our production team encapsulated the duct with spray foam and then administered Aero Seal to the inside of the system to eliminate the opportunity for conditioned air to escape.  This process will stop the duct sweating and keep the conditioned air inside of the HVAC duct from experiencing any external temperature influence.  The air will reach the rooms it is intended to cool or heat and reduce the need for the HVAC system to work as hard as it had been. Improved comfort and reduced energy cost for the homeowner.  

This Dumfries VA home was having comfort issues that the homeowner wanted to eliminate. They called us to come and help.  Our Home Performance Sales Pro Carl completed a no cost inspection of the whole home and identified a need for some work to be done in the attic which would help improve the comfort and energy efficiency of the home.  In addition to air sealing and installation of new Tru Soft cellulose insulation, Carl recommended having the HVAC duct sealed with spray foam at different points where joints and exchange boxes were allowing conditioned air to escape.
