Common Problems With Spray Foam Insulation And How You Can Overcome Them

Spray foam insulation is a highly effective and popular method of insulating the home. Unfortunately, poor installation of the insulation can result in a waste of time and money. If you are thinking of doing the insulation yourself, knowing the most common pitfalls and how to avoid them can help you save energy and money.

Missed Areas

When installing the spray foam insulation, it is important that every area is properly covered. Gaps in areas, such as the attic, can allow air into your home. As a result, condensation can occur and you could end up with growth of mildew and mold throughout the attic and other areas.

To avoid this, it is important that you test the areas you have insulated for signs of gaps. One method is to use a fog machine to smoke out holes in the spray foam insulation installation. Turn on the fog machine in the room that is newly insulated, open a couple of windows opposite the machine, and head outdoors. If there are any gaps, you should see fog or smoke coming from those areas along the walls.

Once the gaps are found, apply insulation to those areas and test it again. When it is right, you should not see any fog coming out of your home.

Insulation Contracts

If spray foam insulation is not properly applied, it can start to contract. Once it does, it will pull away from the frame and leave your home unprotected from the cold and warm air outside. 

The contractions are usually the result of improper mixing, poor quality chemicals, or a foam temperature that is too high.

To avoid problems with mixing the insulation, pay close attention to the manufacturer's instructions. You also need to make sure that you buy the chemicals that are from the same manufacturer. This helps to ensure consistency with the mix and the quality of the chemicals.

You should also test the temperature of your insulation before applying it. Refer to the instructions to determine the desired temperature, and stick to it. When the spray foam is properly applied, you will not have problems with the insulation contracting.

There are other possible problems you can encounter with spray foam. Fortunately, many of those problems are easily avoided by taking your time and following the manufacturer's instructions.
