In terms of improving home energy performance, wall insulation may be the least of your worries. That’s not because wall insulation isn’t important —it is—but most homes already have insulated walls.
Extra insulation is easier to add in the basement, crawl space and attic because foundation walls and attic areas are easily accessible. And these areas are the most likely to be uninsulated or very poorly insulated.
During a home energy audit, Dodrill Comfort & Energy Solutions will be able to inspect and assess home insulation levels. If wall insulation is missing or inadequate, there are several options available to remedy this problem.
Reduce Heating and Cooling Costs with Cavity Insulation
It’s tricky to insulate finished walls because it’s more difficult to get insulation inside the wall, in the cavities between studs. Walls are easy to insulate when the studs are still visible, before wallboard or other finished wall material is installed. One technique for insulating finished walls involves drilling access holes near the top of the wall, and blowing cellulose insulation into empty stud cavities.
Air-sealing is the first step. Whether or not the exterior walls of your home are insulated, there’s a very affordable way to improve their energy performance along with your comfort. If you can feel cold air coming into the house around electrical outlets and window trim on a cold winter day, your walls probably need to be air-sealed. This energy upgrade seals the many cracks, gaps and holes where air leakage occurs.
Don’t overlook windows and doors. The energy performance of an exterior wall has a lot to do with the windows and doors that are installed in the wall. Modern, high-quality windows have features like Low-E coatings and thermal breaks which make them more energy efficient than older windows. The same is true for exterior doors that have an ENERGY STAR® rating. These doors have insulated cores and effective weatherstripping.
