How To Add Spray Foam To Drywall

Adding insulation to your home can often be tricky. You cannot easily open up your walls and pop some insulation inside the studs and then simply close your walls back up. If you don't want to go the DIY route with insulation, you can talk with a professional, like Absolute Air Conditioning & Heating, for more information. However, if you have walls with wooden frames that are finished with drywall, you can add insulation yourself without creating a huge construction project. But, how do you best add this insulation without creating a huge mess? Perhaps the best way to add insulation to drywall is to use spray foam.

Using Spray Foam

To effectively insulate the interior walls of a full-size home, you will need to rent a compressor with a pneumatic spray gun. Insulation sprayers allow you to quickly spray a lot on insulation. You can find disposable insulation spray cans at most stores, but these are much to small for a full home. A single can would probably only fill a single bay between 2 studs. A sprayer allows you to spray larger quantities for much cheaper. Spray foam is sold in a powder form that you just add water to. The spray machines are very simple to operate and the rental comes with complete instructions.

Drilling a Hole Into The Drywall

You will need a cordless power drill to put a hole in between each stud. You will obviously need a stud finder to first mark where each stud is. Drill the hole near the top of the wall and make sure it is slightly bigger than the spray nozzle. Basically, spray until the foam starts to come out of the hole. You will obviously need to patch, texture, prime, and repaint the hole after the insulation is sprayed. You don't need to do it immediately, instead you should wait until the insulation is completely dry. Since there are so many spots that need to be patched and painted, some people decide to just paint the entire wall. In fact, this upgrade is much easier if you do it during an interior paint job.

All in all, this process will take a lot time and patience. However, it is well worth it if home has poor solar and thermal efficiency. You can save a lot of money on your future utility bills with this upgrade. Best of all, the process does not require ant serious demolition.
