Spray Foam Insulation Before & After Photos

A great way to improve the comfort and energy performance of a home is to apply Spray Foam to the rim joists at the top of the basement foundation walls.  This space can often allow outside air and temperatures to impact the home.  Cold or hot air from outside can cause temperature fluctuations and can carry in dust and allergens that can impact the air quality in the home.  50% of the air inside of a home comes from the lowest points of open air access in the home so creating a low point that is not in or near a basement can keep moisture out as well.  Our production crew applied Spray Foam to this entire basement at all of the rim joists and created and air seal along with better insulation.  

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.
