This Arlington, VA homeowner was remodeling their home and wanted to use spray foam for their basement. Comfenergy recommended a closed cell spray foam without a thermal barrier for this project. This type of spray foam was used for its ability to be a vapor barrier. Also, the spray foam was being covered up by drywall, so there was no need for a thermal barrier.
One of the biggest culprits of heat loss in the winter (and high energy bills) is recessed can lights that back to the attic. The attic is outside the home and the top floor in inside the home. These can lights are 6" holes in the ceiling that allow heated air out of the home. Covering them and sealing them keeps the heated air in longer and lower the usage of the heating system.
This Linden, VA homeowner had mold growing on the drywall in the garage ceiling that was causd by the HVAC duct work above the drywall sweating in the summer time. This duct sweating is caused by hot/humid air hitting the cold metal ducting. This makes the air hit dew point and sweat. Then, it dripped on their drywall and over time caused mold to grow.
Comfenergy removed and disposed of the dryall where the mold was growing. Then, we completely encased the metal ducting with closed cell spray foam to air seal it and protect it from the hot/humid air entering the cavity the duct runs through.
This Jeffersonton, VA homeowner has suffered from high humidity in the basement of their home for years. The basement is attached to a low ceiling crawl space built on a slab. The high humidity is typically caused by:
1. Drainage of ground water from outside.
2. Hydrostatic water table pressure coming up from below.
3. Hot/humid air coming into the basement and hitting cold surfaces.
These before and after photos show how Comfenergy solved the humidity issue. A perimeter drainage system was installed in the slab around the perimeter of the crawl space. CleanSpace (20 mil) vapor barrier is tucked behind the perimeter drain. Then Thermax foam wall panels are installed to provide the proper air sealing and insulation value. Thermax also provides a thermal barrier for fire protection and meet codes.
Now the basement and crawl space are nice and dry!
This Flint Hill, VA homeowner always had a cold basement, specifically their laundry area. Presently, it was insulated with loose fiberglass batts pinned to the wall. This neither stops air from traveling into the home, nor provides much of a thermal barrier. The rim joists at the top of the wall were also merely insulated with fiberglass batts.
Comfenergy put together a solution that was effective, and appealing to the eye! The fiberglass was removed and disposed of. Thermax (polyisocyanurate) boards were attached to the walls, with foam and tape sealing the gaps. Then, the rim joists were sprayed with closed cell spray foam to air seal and insulate them too.
Now the homeowner can perform laundry duties no matter what time of year it is!!!
This Boston, VA homeowner had issues staying warm in the winter and cool in the summer. A FREE comfort evaluation by Comfenergy revealed, among other things, an HVAC ducting system located in the attic that was both leaky and not insulated. The hot air was leaking into the attic in the winter. The cold air was becoming re-heated in the summer. Not only was this causing discomfort, but it was making their utility bills go literally through the roof!!
Comfenergy encapsulated the attic ducting system to seal it from those air leaks. This keeps all of their air in the home! It also insulates the air travelling through the ducting system so that it comes out of the vents at the right temperature to stay comfortable.
