Comfenergy Before & After Photos

A cantilever hangs out past the foundation walls of a home and can allow for external air and temperatures to impact the inside of the home if not properly insulated and sealed.  Cold air from outside can make the floors connected to the cantilever cold and allergens or dust from outside can work its way into the air inside of the home.  Spray foam insulation is a great way to not only insulate the floors connected to the cantilever, but to air seal the space to allow for better air control in the home.  

This attic project in Alexandria Virginia included multiple solutions to help improve the comfort and energy efficiency of this home.  In addition to air sealing and HVAC duct management, we installed Silver Glo insulation panels to sections of the attic walls.  Silver Glo paired with air sealing using Zyp Foam, will keep the temperature in this attic controlled and help the HVAC ducts deliver conditioned air more efficiently.  

There were severs drafts coming through the knee-walls of this Alexandria, VA home. Comfenergy used closed cell spray foam to air seal and insulate them to stop these drafts. 

This Alexandria, VA home had a tremendous amount of air drafting through the knee-wall/storage space.  Comfenergy used Thermax foam boards to air seal and insulate them. Thermax is used in storage areas due to its ability to also provide a fire resistant flame barrier per code.

The following before/after pictures are from a knee-wall in Alexandria, VA that we encapsulated with closed cell spray foam.  This made the top floor warmer in the winter, and cooler in the summer....plus lessens draftiness on this level of the home.
