How Spray Foam Insulation Can Help Your Home Efficiency

If you live in a finished home, with attached, textured, and painted drywall, it is not too late to add insulation to your walls. The space in between your studs (also known as the drywall or stud bays) is usually hollow. This is obviously not very efficient or sound proof. With a little insulation in the stud bays, your walls will retain heat much better. This can ultimately reduce your utility bills and save you good amount of money over the years. The best way to add insulation to your finished home is to use spray foam insulation. This article explains how your can add spray foam insulation to your own walls, even if you aren't a construction expert.

The Best Tools for the Job

You can find disposable spray foam cans on the shelves of a home improvement store. But these are not great for large jobs. If you want to do a couple of entire walls, you will burn through a lot of cans and it will cost you. You can save money by renting a pressurized spray foam insulation kit. These work similar to pneumatic paint guns. Pressurized air propels the foam through a gun. You use a powder mixture that you add water to. This is much cheaper than using the cans. It also enables you to spray much more insulation in a shorter amount of time.

Prepping the Walls

You will need a stud finder and a power drill for the job. Mark, at the top of the walls, the center point between each stud. Use a drill bit that is slightly larger than the gun's hose. It is very important that the hose fits all the way inside the hole. You basically spray into each bay until the foam starts to come out the hole. Even though each bay should be the exact same width, this does not mean that each will absorb the same amount of insulation. Often, there will be crossbeams, wiring, or tubes in the bays that take up additional space.

Wait for your insulation to dry completely (this should take a couple of hours) before you start to patch the hole. Of course, this is much easier if you still have your original paint. Otherwise, this is a smart job to do right before you repaint your interior.

This is a cheap and surprisingly simple home upgrade that will manifest itself through your reduced energy bills.
