Where And How To Use Spray Foam Insulation

Posted on

Insulation is one of the easiest ways to lower your energy bills. Increasing the amount of insulation not only keeps your home warmer in winter, it also helps hold in cool air so it's more comfortable in summer. You don't need to rip apart your home to install batts of insulation. There are many places in your house that can benefit from spray foam insulation.

The Attic

Attic installations are perhaps one of the more common uses for spray foam. Often, a home may have a poorly insulated attic. Since heat rises, this can mean lots of energy loss. Spray foam can be used liberally between the ceiling joists to provide an instant improvement.

Detailed cleaning isn't necessary, although you will want to make sure that the area is dusted so the foam can bond to the surface. If you opt to do this yourself, you will need to purchase a low pressure spray foam insulation kit, along with protective gear such as goggles, gloves, and a respirator mask. Ventilation is also a must, and you need to make sure that there are no open flames since the fumes of spray foam can pose an ignition hazard until the foam dries. If this sounds like too much, you can hire a professional insulation installer to handle the job.

Air Leaks

Air leaks are sometimes present around door or window frames, pipe and cable entry points into the home, plumbing pipes, holes around HVAC systems, and around the dryer vent. These are also all suitable places to install spray foam insulation. Instead of worrying about a low pressure installation rig, you can use spray foam in a can for these small jobs.

Make sure you have face and eye protection, and work in a well-ventilated area. Shake the can well, and then spray the foam into the area that needs insulation. Fill the area about half-way, since the insulation expands. You can top of the spot if necessary once the first application dries. If it expands too much, simply trim off the excess with a knife once it dries.


Spray foam is also an excellent way to add more insulation to your walls. Small holes are drilled in the wall boards between the studs, and then an insulation hose is inserted and insulation is sprayed into the cavities to fill in any gaps. This insulation is often applied under high pressure, so it requires an insulation professional to do the work. This is because high pressure rigs can be dangerous to operate without the proper training, so it isn't a job for the novice. Once the insulation dries, the holes are patched and repainted.
