Many people mistakenly think that wall insulation only helps save energy when heating the house. The fact is that good wall insulation also helps save money on air conditioning and can lead to some of the most dramatic savings in areas with long, hot summers. So what does adding wall insulation to your house entail? Here are the basics of what you need to know:
Wall insulation can be added at any time
You do not have to rip out walls or open up large holes in order to add insulation to your walls. Wall insulation specialists have several options for insulating existing finished walls, which provide noticeable and immediate benefits in terms of your energy usage and heating or AC costs. To insulate finished walls, a small hole is drilled into the wall and insulation is sprayed through the hole. One hole is drilled between each set of studs. The process is easy and inexpensive.
Interior walls can also be insulated
Most homeowners seek to insulate their exterior walls for the obvious reasons: these are the walls that heat leaks through to or from the outside world. However, there are many reasons to consider insulating select interior walls as well. For example, if you have a wall bordering a garage, it makes more sense to insulate that wall and leave the garage uninsulated, ultimately saving money by insulating a smaller area. Similarly, some homeowners may want to insulate walls against rooms that aren’t used often so that heat or AC can be contained to high use areas.
All holes will be plugged and disguised
Drilling holes in the walls makes many homeowners nervous, but a good wall insulation professional will leave no sign that they were ever there. In the case of interior walls, drywall is easily patched and repainted. For exterior walls, siding is either removed before drilling (aluminum, vinyl) and then re-installed over the plugged hole, or drilled through (wood) and then closed with a wooden plug that is sanded and repainted to make the outline of the hole all but invisible.
Home renovations are a great excuse to insulate walls
Any time you are performing home renovations that include knocking out drywall inside or removing siding, it’s the perfect time to add wall insulation as well. Wall insulation is even easier to add to an open wall, so why wait?
