    CleanSpace Encapsulation System in Herndon, VA

    A homeowner in Herndon, VA wanted to reduce the chances of mold and humidity in their crawl space area. This crawl space was vented, like most homes in our area, and the vents let warm humid air in which is cooled by the subterranean crawl space. This causes relative humidity to go way up and condensation to form all over the crawl space surfaces including floor joists and ducts. Then mold can grow, wood will rot, and musty odors can appear. To address this, Comfenergy sealed up the vents and a dimpled plastic drainage matting is installed on the floor to create a thermal break. A heavy duty liner, CleanSpace, is installed across the floor over the matting and up the walls. Finally closed cell spray foam is installed on the walls to the top of the rim joist.

    Fiberglass versus TruSoft Cellulose- Lorton, VA

    This set of before and after photos shows the difference between light, fluffy fiberglass insulation and new TruSoft cellulose insulation in an attic.  Here are the differences you may not know:

    1. Fiberglass is more susceptible to something called "wind washing".  In a vented attic assembly wind can blow around in the attic and it can easily pass through the fiberglass.   TruSoft cellulose packs tighter and it's harder for wind to travel through it.

    2. Rodents and insects LOVE fiberglass.  They nest in it and make it home.....right above your head.  TruSoft cellulose is chemically washed with a liquid borate which deters rodents and insects by irritating their respiratory system.

    3. TruSoft cellulose has a higher R value per inch than fiberglass.

    4. TruSoft cellulose is also less succeptible to flame spread than fiberglass as well.....

    Turning Attic into a Conditioned Space - Prince William County, VA

    A home owner in Prince William County, VA wanted to make his home more energy efficient. One of the ways that we helped them do this was by converting the attic into an extension of conditioned space. We did this by installing an average of 3 inch thick closed cell spray foam on the roof and the end walls. This creates a super insulated airtight cap on the top of your home to stop air from leaking out. Closed cell spray foam insulation has a leading R-value of R6.5 per inch and adds to the structural integrity of your roof. Converting this attic resulted in lower fuel and energy bills.
