Spray Foam Insulation Before & After Photos

Skylights are beautiful, but can increase heat loss/gain tremendously, just like in this Leesburg, VA home. Especially if they are not properly air sealed and insulated on the back side of them in the attic above.

This before/after slection comes from Bealton, VA. The room on the other side of this wall was hot in the summer and cold in the winter. Thermal imagery from the room side showed a ton of thermal bridging which was making the room uncomfortable.  Comfenergy used a closed cell spray foam to solve 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 roofing company contacted us to insulate a flat roof during the process of them replacing it. These pictures show the before and after of Comfenergy's portion of the project.

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!
