As a homeowner, you want your house to have great insulation, since without it your cooling and heating bills will skyrocket. The best insulation in the world won't matter though if it is not installed correctly. Foam that is not applied properly in critical spaces will be nothing more than an expensive wall covering. That's why you need to avoid these potential problems during the insulation installation.

Ensure Proper Thickness

Spray foam insulation needs to be the correct thickness to make the insulation effective in your home. Foam that is thin will not get the job done, and foam that is too thick could be a huge expense that is not necessary. Make sure to inspect the attic after having spray foam insulation installed.

Insulation that is the proper thickness will feel just like the other walls of your house when it comes to the temperature. If the foam feels notably cooler or hotter in your attic, it is a sign that not enough insulation was applied.

The thickness should also be even throughout the entire insulation. Take a close look at places where the insulation dips toward the exterior wall. These can be places where the insulation is weak and needs more to form a proper thickness.

Get A Pre-Visit Inspection                                                                                                

To get the best results during an insulation installation, the contractor should visit your home prior to performing any services for you. They will need to inspect your home to find common air leaks. They'll look for places where hot air escapes, such as the sill plate, top plate, duck register, and attic hatch. They'll also identify places where cold air leaks in, like crawl spaces, vent fans, outside faucets, and windows.

Finding all of these areas is a time consuming process, often taking as long as the installation. If your contractor insists on only visiting your home once on the day of the installation, it's likely that they will not have the time for performing a proper inspection and seal all of the leaks in your home. Even if your contractor uses a very thick foam layer in places like the attic, missed areas will be what contributes to heat loss and gain.

Communicating with your insulation contractor will be key to avoiding and problems with a spray foam installation. If you ask the right questions and express the proper concerns, it will help give you the peace of mind that everything is going smoothly.
