Spray Foam Insulation Before & After Photos

There are many places in the frame of a home that can allow for external air and temperatures to impact the comfort inside of the home. This Fairfax Virginia home had cantilevers where the different levels of the home met and they were not insulated.  This lead to cold floors inside.  Our production crew removed the underside panels of the cantilever and used spray for to air seal and insulate.  

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.  

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.

In the summer attic temperatures can reach over 120 degrees.  In the winter attic temperatures can drop to below freezing.  Trying to pass cold air through a 120 degree metal HVAC duct in the summer just wont work well and moving heated air through a cold metal HVAC duct in the winter will not either.  this can cause an HVAC system to run more often than it should, increasing energy costs and can leave homeowners with rooms that are less comfortable than others.  We removed the existing insulation in this attic in order to expose the full HVAC duct system so that it could be encapsulated with Spray Foam.  This will protect the conditioned air travelling inside.
