Basement Wall Insulation Options Basement Wall Insulation Options
If you’re planning a basement wall insulation project, you will have to decide which type of insulation to use. The kind of insulation you install will vary depending upon the condition of the walls. If the walls are at a point where they are still unframed or framed but not finished, you have the most options. If the walls are already finished, you have fewer options.
If you are constructing the walls, you have the opportunity to choose the type of insulation which you would prefer. Rigid foam panels are often used in basement construction. They come in 4x8-foot sections and can be trimmed to fit any space using a handsaw or a utility knife. The rigid foam insulation produces about twice the “R” factor of other types of insulation, but the price also reflects that quality. A less expensive option is the fiberglass batt insulation, but it won’t be as effective.
If the walls are already constructed, but poorly insulated, there is something you can do besides tear the walls down and start from scratch. You can pump liquid foam or loose insulation into the walls by cutting a hole in the wall large enough to accommodate the pump, and then add the insulation. After you repair the holes, you should have a much more energy efficient basement.
It’s always nice to be able to choose the type of insulation you would like to use in your basement, but all is not lost if that’s not possible. Working with the walls you already have is an option as well.
