How To Insulate Your Existing Walls

One of the best ways to keep a room properly conditioned is to insulate the exterior walls of the home. Proper insulation keeps warm air inside in the winter, cooled air in the summer, and makes you more comfortable as your family goes about their daily lives. How To Insulate Your Existing Walls

However, insulating exterior walls is a fairly new process. If your home was built before the 1980s, insulation requirements didn’t exist with the codes and policies of the times. That means there’s a good chance your home is missing this valuable resource. 

How do you know if your home is properly insulated? A quick inspection will tell you that. 

It’s easy to determine how much insulation is in your attic or crawl space. A visual inspection will reveal how much insulation is there, and what condition it’s in. But your exterior walls are a little more difficult. 

To check your walls, do one wall at a time. Start by turning off the electrical power along that wall. Once you test that the power is off, remove the outlet cover plate and determine if there is insulation around the perimeter of the box. If it’s not there, there’s a good chance they haven’t been insulated. 

Which means it’s up to you to fully insulate them to make your home a more comfortable place to live.

A home’s exterior walls can be insulated either from the inside or outside. 

From the outside, the contractor will remove a few side panels so that a hole can be bored through to the top of the wall stud cavities. Then using a hose and specialized equipment, the contractor will blow fiberglass or cellulose insulation through the hole and into the hollows of your wall. When the job is finished, the hole is sealed, and the boards are replaced.

From the inside, the job is performed in a similar manner. Instead of removing boards, the hole is cut through the drywall, the specialized equipment is inserted, and the insulation is installed. Repair work is a little more intensive, as the drywall will need to be patched and the walls painted. It can also be quite messy during the process, so you’ll need to protect your furniture and other personal belongings too. 

While you can find the tools you need at your local big box store, this isn’t a DIY job. There are a lot of nuances to getting this right. At best, nothing goes wrong and your home is more comfortable. But at worst, you can release harmful chemicals into the air supply, which can impact your family’s health. If not installed properly, it can also be subjected to biological growth forming easier than before.
