Spray foam insulation has increased in popularity due to its improved energy efficiency and ability to form an airtight seal in residential and commercial buildings. Despite its benefits, some myths and misconceptions keep some individuals from considering it as an insulating choice. These beliefs, which range from safety concerns to cost estimates, can be confusing.
Let’s dispel some of the most popular myths regarding spray foam insulation and uncover the truths so you can make an informed decision about your insulation needs.
1. Myth: Spray foam is toxic and unsafe for homes.
Spray foam insulation is safe and does not offer any health risks when professionally installed. Not only that, but it also contains fewer VOCs (volatile organic compounds), and since it has no food value, it doesn’t encourage mold or bacteria growth, which keeps your home and indoor air quality healthy.
2. Myth: Spray foam insulation causes roof rot.
This misconception is based on fears that the airtight seal holds moisture. However, spray foam insulation helps to prevent moisture buildup, and when installed properly, it can actually shield roofs and other construction components from water damage.
3. Myth: Spray foam insulation isn’t environmentally friendly.
Modern spray foam insulation, made from renewable materials like castor oil and soy, can reduce a building’s energy usage and carbon footprint. Plus, spray foam lasts longer than other insulation products, so it doesn’t need to be replaced as often. This reduces waste and the energy needed to produce and transport new insulation.
