Over time the insulation in your walls can settle toward the bottom leaving an empty cavity near the top. Oftentimes homes are built with budget in mind and contractors simply skimp on the insulating process. In some older homes there may not be any insulation at all. If you can feel cold areas in the winter and warm or hot spots in the summer than most likely your walls are in need of our services.
Blowing cellulose insulation into existing walls is an effective way to improve the energy efficiency of your home. Here are the general steps involved in blowing cellulose insulation into existing walls:
1. Drilling holes: A professional insulation contractor will first drill small holes into the walls, typically through the exterior siding or interior drywall.
2. Blowing in the cellulose: Using a specialized machine, the contractor will then blow the cellulose insulation into the walls through the holes. They will use an appropriate nozzle to direct the insulation to fill the space between the interior and exterior walls.
3. Patching holes: Once the cellulose insulation has been blown, the contractor will patch the holes in the walls with either foam plugs, wooden plugs, or drywall.
Some considerations to keep in mind when blowing cellulose insulation into existing walls are:
1. The size of the holes: The holes must be drilled at carefully selected locations to allow easy filling of the cavity and to avoid damage to any electrical wires or structural elements inside the walls.
2. The type of cellulose insulation: There are different types of cellulose insulation, such as dense-packed and spray-applied. A professional insulation contractor will recommend the most suitable option for your home’s insulation needs.
3. The insulation’s settling: Over time, cellulose insulation may settle or shift within walls, reducing its effectiveness. A professional contractor will use the appropriate techniques to minimize settling and ensure that the insulation remains in place over time for best results.
