How Do You Insulate Airspace Between Wall & Insulation?
Improving the insulation in your home can lower your energy costs, reduce unwanted noise and increase the value of your home. Cold air and sound leaks into poorly insulated homes through windows and doors, attics, floors and even walls. The air space between formed walls and current insulation is a great spot for insulation improvement. This narrow space is best insulated with blow-in insulation, which is made up of highly compressed, loose fibers or cellulose. Blow-in insulation can be added by simply drilling a hole into the wall and utilizing a blowing machine. Determine the amount of insulation recommended for your area. Cold regions require 10 to 16 inches of insulation, while milder regions may require less. Visit the Department of Energy’s website for the official insulation recommendations for your ZIP code. The recommended insulation amount will be provided as an “R-value.” Rent a blowing machine from your local hardware store, and purchase loose fiber or cellulose insulation.
