Insulation is present in virtually any construction project. From fiberglass and mineral wool to calcium silicate and polyisocyanurate, there are a variety of insulation options on the market today. Each of these options has its pros and cons and is appropriate for a specific application or project.

Spray foam is one of the most versatile forms of insulation. When applied correctly, it can be an effective insulator for all kinds of projects. It is very different from other kinds of insulation, and these differences may need to be clarified to properly inform a customer who is not familiar with the nature of the product. This article addresses some common misconceptions about spray foam and discusses the benefits of properly applied spray foam insulation.

Misconceptions about Spray Foam Insulation:

1. Moisture Issues
Critics argue that spray foam insulation acts as a sponge, trapping moisture in an insulated space and leading to mold, material breakdown, or other structural damage. It is important to note that the inherent presence of spray foam does not typically cause moisture problems. These problems often stem from outside sources unrelated to the spray foam product, such as roof leaks or installation errors. Spray foam is a safe and effective product and does not negatively affect an applied surface – in fact, closed-cell foam increases the structural integrity of a building by up to 300%.

Spray foam should be installed alongside an air exchange or HVAC system and given proper, routine maintenance. If properly installed and maintained, any moisture-related concerns can be avoided.

2. Chemical Concerns
The composition of spray foam is very different from other forms of insulation, and as such, it has been the subject of debate. You may have questions about the chemicals used in spray foam insulation, especially as to whether they are safe or if they might present potential health hazards.

Spray foam is comprised of a blend of materials and should only be applied by trained professionals who know how to handle these chemicals safely. After proper application, the spray foam dries and cures. After the curing process, the spray foam becomes an inert cellular plastic that is safe to be around without PPE. It will not release off-gasses past its initial cure process, similar to the foam used in foam mattresses or seat cushions.

3. Limited Application
There is a perception that spray foam insulation is only suitable for specific areas, such as basements. In reality, spray foam is ideal for use anywhere a superior insulation is desired, including walls, roofs, and attics. Its versatility and ability to create an airtight seal make it a valuable insulation option for both residential and commercial buildings. A properly trained insulator can apply spray foam to virtually any surface, allowing you to enjoy the benefits of spray foam on a range of projects.

Environmental Benefits of Spray Foam Insulation:

1. Energy Efficiency and Air Leakage Reduction
Air infiltration is responsible for up to 25-40% of increased energy costs. Spray foam helps to mitigate air infiltration by providing exceptional thermal insulation. Once dried and cured, it creates an airtight seal. Not only does this eliminate drafts, but it helps maintain the temperature in a treated space, leading to a more comfortable, controlled environment. With the temperature controlled, a treated area no longer needs excessive heating or cooling. By reducing this need, spray foam directly contributes to lower energy consumption and utility costs.

2. Sustainable Construction
Spray foam insulation offers several sustainability benefits. Like any manufactured product, it does have a short-term environmental impact from its manufacturing process. This impact is immediately neutralized and mitigated by rapid ROI and long-term energy savings.

As discussed, spray foam reduces the potential for heat loss or gain and improves a building's energy efficiency. Reducing energy use reduces carbon emissions, helping to lower a building's carbon footprint. Spray foam can serve as an accessible introduction to eco-friendly building practices, empowering owners and building managers to make more eco-friendly choices in the future. Additionally, spray foam has a long lifespan. Its staying power means that it does not have to be repaired or replaced as frequently as traditional insulation. This makes spray foam a more environmentally friendly and economical choice when compared to traditional insulation, which may have to be removed or destroyed to make repairs.

3. Mold and Moisture Resistance
Properly installed spray foam insulation forms an airtight barrier. Closed-cell spray foam is also a class II vapor retarder. It prevents outside air and moisture from infiltrating a treated space. By preventing external water from entering an area, it eliminates mold and other moisture-related issues. This contributes to maintaining a healthier indoor environment.

In conclusion, spray foam insulation is a safe and effective product that can be used in a variety of applications. It provides many benefits, including enhanced energy efficiency, improved indoor air quality, and long-term sustainability. By educating ourselves on the numerous advantages of spray foam insulation and dispelling misconceptions, we can make informed decisions regarding insulation choices and contribute to a greener and more sustainable future.
