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!!!
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.
Can lights leak air from you home into the attic (which is outside your home). It's very similar to leaving the windows open 24/7/365 even when heating and cooling the house. You are paying for that heated and cooled air.
Rock wool can light covers not only seal this heated and cooled air in your home, and preventing it from leaving.
It keeps any flammable materials away from the can light which can reach temperatures allowing wood and certiain types of insulation to catch fire!!!
This Charles Town, WV homeowner had issues with cold floors and freezing water lines during the winter. Comfenergy solved both by installing TerraBlock floor insulation, covered it with CleanSpace 20 mil vapor barrier, and insulated the walls with closed cell spray foam insulation.
Sometimes comfort and energy issues can be caused by leaky and poorly insulated HVAC ducting. The before/after pics that follow show a duct that was poorly insulated, running through a cold attic in the winter. Hot air was leaking into the attic instead of going to the room to deliver the hot air. Plus there was little to no insulation on it which was "cooling down" the heated air making it less efficient.
Comfenergy sealed the ducting and insulated it with an R13, closed cell spray foam. This seals the duct leakage and insulates it to better than the existing code (R8)
