How To Add Insulation To Your Floor

Posted on: 30 January 2018


If you have a home with a basement, there is a good chance that you will be able to add extra insulation to the floor on the main level. Basements usually don't have the same temperature control as the rest of a house. This often means that this cold air permeates through the floor, making it cold to the touch, but also cooling down your entire home. So, if you can add some insulation to the floor via the basement, you can make your home a little more energy efficient, especially during the winter.

Exposed Basement Ceiling Joists

When many new homes are built, the contractor purposely leaves the basement undone. That is, the walls might have drywall, but they don't have an texture, paint or finishing. Many basement ceilings are also left without any drywall at all. This enables the homeowners to more easily add and customize their electrical, plumbing, HVAC and other vital pipes.

Most homeowners never add drywall to their basement ceiling joists. Because of this, the cold air in the basement can have a more noticeable impact on the temperature on the level above it. Luckily, if your basement ceiling joists are exposed, it is much easier to add insulation to them. This is essentially adding insulation to the floor on your main level!

How to Add Insulation

Fiberglass batting-style insulation is the best product for the job. Most products come 15.5" wide, so they can easily fit in between the stud bays. You only need to cut them to the right length at the edge of the joists. The fiberglass can be easily cut with scissors or a razor blade. You will just need a staple gun to attach the fiberglass to the drywall.

Fiberglass insulation is extremely fibrous and itchy if it comes in contact with your skin. You should wear long sleeves and protective eye-wear while doing the work. The job is a little uncomfortable because you need to use a ladder, crane your neck, and always look up. However, you don't need any complicated tools or construction skills, so it is a great DIY project.

If you want to go a step further, and add even more insulation to your floor, you can get an insulation company to add drywall to your basement ceiling after the insulation is added. This is going to be an expensive additional project, but it is going to have a bigger impact on the insulation of your floors.
