Spray Foam Insulation Before & After Photos

This Midland, VA homeowner was looking to find a way to make the top floor rooms on the back of the house warmer and less drafty in the winter. Upon a full evaluation by Comfenergy, we found the main culprit to be the cantilever on the back side of the house allowing cold air up under the floors on the back side of the house.

Comfenergy opened the rear cantilever to find almost no insulation whatsoever.  Plus there were no real rim joists to slow or stop the air from entering beneath the floors above. Comfenergy used SilverGlo foam boards to create a rim joist. We then used closed cell spray foam to air seal and insulate the cantilever.

The rooms on the back side of the house are nice and warm now!

This home in Haymarket, Virginia has a unique architecture for the area and the turrets you see ont he front of the house were too hot in the summer and too cold in the winter.

Comfenergy used spray foam to fix the problem.

This Gainesville VA home was designed with Cantilevers on several sides of the home.  "Cantilever - a long projecting beam or girder fixed at only one end, used in construction."  In this case it resulted in part of the home allowing external air and temperatures to come into the unfinished basement, impacting the air quality, energy control and general comfort of the home.  Our Home Performance Sales Pro Pedro went out to do a full home inspection and recommended having the cantilever areas filled and insulated with spray foam.  Spray foam helped to seal up the cantilevers and prevented external air and allergens from being able to enter the home.  It also helped to keep the inside of the home more comfortable.  

A homeowner in Goldvein, VA needed some insulation in his home. Heat moves from more to less - out of a building in winter and into a building in summer. Insulation is needed to slow this heat flow down.  Closed cell spray foam adheres to all surfaces, expands in place, and air cannot pass through it. It is superior insulation with an R-value of 6.3 per inch. Closed cell spray foam weighs 2 lbs per cubic foot and special equipment is used to spray it. 

This before photo shows a vertical wall in an attic insulated with fiberglass insulation. This fiberglass allows hot/cold air to travel through it and touch the drywall, thus allowing the heat and/or cold to transfer into the living space.

The after picture shows the fiberglass removed and newly insulated using closed cell spray foam.  This builds a great protective thermal and air barrier and makes the top floor of this home cooler in the summer months.
