If your attic is properly insulated and air-sealed, but you’re still experiencing fluctuating temperatures and high energy bills, chances are you need to add insulation to the exterior walls of your home and air-seal any entry points. Why? Roughly 35% of energy escapes through the walls.
In an existing home, consider using blow-in insulation, which, when installed with the dense pack technique, will provide significant air sealing and is less invasive than using batt insulation. We simply make a three-inch diameter hole to inject the insulation and help with repairs if you ask us to. If the wall cavity is open, it is much easier to install batt insulation.
