Spray foam insulation has gained immense popularity in recent years due to its superior insulating properties and air-sealing capabilities. However, as with any new technology, there are several myths and misconceptions surrounding its use. In this blog post, we’ll address some of the most common myths about spray foam insulation and provide you with the facts.

Myth #1: Spray Foam Insulation is Toxic

One of the biggest myths surrounding spray foam insulation is that it’s toxic and can cause health issues. The truth is, when installed correctly by a professional spray foam contractor, the insulation is safe and meets all necessary building codes and regulations. The chemicals used in the installation process are designed to be inert and non-toxic once cured.

Myth #2: Spray Foam Insulation is a Fire Hazard

Another common misconception is that spray foam insulation is a fire hazard. In reality, most spray foam insulation products are designed to be fire-resistant and meet stringent fire safety standards. They can help prevent the spread of fire by sealing off potential entry points for flames and smoke.

Myth #3: Spray Foam Insulation Can’t Be Used in Crawl Spaces

Contrary to this myth, spray foam insulation is an excellent choice for crawl space insulation. It not only insulates the area but also creates an air barrier, preventing moisture and pests from entering the home.

Myth #4: Spray Foam Insulation is Too Expensive

While spray foam insulation may have a higher upfront cost compared to traditional insulation materials, it offers long-term savings by reducing energy bills and increasing the overall energy efficiency of the home. Additionally, the cost of spray foam insulation has become more affordable in recent years as the technology has advanced.
