Expanding foam insulation is a common choice among homeowners due to its effectiveness in sealing gaps and reducing air leakage. However, it’s important to know that there are some situations where spray foam insulation should not be used. One of these situations is when insulating around outlets or can lights that are recessed. Here are some reasons why:
Expanding foam can cause overheating and create a fire hazard when sprayed around electrical outlets or can lights that are recessed.
Spray foam insulation can also disrupt the electrical wiring or connections that are necessary for the outlets to function properly.
Expanding foam can expand too much and cause the outlet cover to become misaligned, making it difficult to cover completely.
When insulating around outlets or can lights that are recessed, it’s best to use a non-expanding insulation such as fiberglass batts or foam board insulation. These materials are safer and more effective for these areas, ensuring that your home is properly insulated while also reducing the risk of electrical hazards.
