These before/after pictures are of Rcok Wool insulation being wrapped around a furnace flue pipe in the attic. This rock wool is a flame resistant type insulation material that keeps the heat away from the fiberglass or cellulose insulation. Thus, protecting the house from catching fire!!!
This Linden, VA homeowner was hving trouble keeping the top floor cool in the summer. After a thorough comfort evaluation by Comfenergy it was determined that their HVAC ducting system was leaky and poorly insulated. The air coming into the rooms was actually higher than the thermostat setting.
Hard to keep a room 72 if the air you're pumping into it is 85!!!
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.
Spray foam and Tru Soft cellulose insulation are a great combination of products to help improve the performance of an HVAC system in a home and can help to reduce energy costs. Protecting the air travelling through an HVAC duct by eliminating the influence of attic temperatures can help keep the conditioned air travelling through at the temperature it is intended to be at to help heat or cool the rooms it is being sent to. We removed the existing insulation in this attic before air sealing the space with Zyp Foam and then encapsulating the HVAC duct in Spray Foam. Afterwards we blew in Tru Soft Cellulose insulation to add the extra layer of protection and insulation.
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!!!
