Wall insulation is any type of insulating material that is attached to or placed within walls. Normally, the main function of wall insulation is to increase the climate efficiency of the space by making it easier to heat and cool the room. Depending on the type of wall insulation used, the product may also help to soundproof the space and minimize the amount of noise that enters or escapes from the room.
Various types of insulating products are used for proper wall insulation. When the task is to insulate walls in a home that is under construction, it is not unusual to use rolls of fiberglass insulation that can be cut to the right lengths and tacked to the interior area between each side of a finished wall. In this application, the cut sections of insulation are secured in place before closing up the wall. The result is interior walls that minimize sound transference between rooms and exterior walls that effectively block the entry of outside heat in summer months while also preventing cold from entering the home during winter months.
When installing insulation in older homes, rolled insulation may not be the most viable option. However, there are a couple of other options for wall insulation that are worth consideration. One is the use of foam insulation. The foam is blown in to the walls, often from the attic area. As the foam enters the open space between wall facings, it expands and effectively fills in the open area.
A second wall insulation option for older homes is the use of insulating chips. As in the case of foam insulation, machinery is used to blow in the chips and fill the open spaces within the walls. While the chips do not expand like the foam, they can easily fill the space and create an effective barrier than makes heating and cooling interior rooms a much more energy efficient task.
An insulated wall provides a number of benefits for the occupant of the building. Wall insulation makes it easier to heat and cool the space and save money on power bills. Depending on the type of insulation used, there may also be a significant reduction in noise within the space, since many types of wall insulation have soundproofing qualities. The insulation may also help to seal tiny cracks where the house has settled and the joints are no longer in perfect alignment.
Installing wall insulation is not a task limited to professionals. Homeowners may choose to handle the job of insulating the home themselves. However, it is a good idea to consult a professional in order to choose insulation products that are right for building type, and will take into consideration of factors such as humidity control and soundproofing if those are issues of importance to the owner.
