Spray foam insulation is the bonanza of rectifying solutions for the modern homeowner. This multipurpose material is an innovative remedy that works wonders to reduce energy use and prevent air leakage and infiltration. Not to mention its other perks—such as minimizing heating and cooling costs—can help create a comfortable home environment for years to come.
If you need to fill in cracks, holes, and air leaks in your living spaces, foam insulation is a beneficial option that expands to fit within a specified area and quickly hardens, providing an adequate barrier against undesirable materials. Regardless of this product’s versatility, spray foam isn’t foolproof. Let’s take a look at the areas in your home that are typically off-limits. Here’s where not to use expanding spray foam insulation.
AROUND ELECTRICAL OUTLETS OR BOXES
Spray foam provides an effective air barrier when properly installed, making it a popular choice for difficult-to-insulate spaces. However, one area where we would not advise to use expanding spray foam insulation is in spaces too close to electrical mechanisms, such as outlets or boxes. If foam were to get inside the box or outlet, the components could jam up.
Most critically, the spray foam contains flammable chemicals that could spark a fire when exposed to electrical parts. Expanding insulation should not be used in or around these parts or other electrical wiring—it’s not worth the safety risk.
UP ON THE ROOFTOP
The use of spray foam on the roof of a home is a debated topic in the industry. While expert contractors have previously accomplished this spray foam application, it generally isn’t recommended. Out of the wide array of roofing insulation options, the use of open-cell spray foam is not a good option.
A variety of problems can arise, such as trapped water, increased moisture, and potential spoiling. Furthermore, the majority of residential homeowners undoubtedly wouldn’t want a spray foam roof for aesthetic reasons.
Rates of expansion differ between types of insulation foam, which can reduce the efficiency of the insulation. This relates to the next area of installation limitation. If you were to install expanding spray foam insulation in a closed cavity, you could potentially end up with damaged drywall or spots void of proper insulation. The foam may not cure due to the lack of air and moisture. It’s difficult to say what coverage you would receive.
