What is Spray Foam Insulation?
Spray foam insulation is a type of insulation that expands to fill gaps and cracks, creating a durable barrier between your indoor living space and the great outdoors.
There are two types: open-cell and closed-cell. For Michigan homes, we recommend closed-cell spray foam due to its high R-value and ability to block moisture, making it ideal for Michigan’s variable climate.
Spray foam can be applied in areas like basement rim joists, crawl spaces, knee walls, and attics. By insulating these areas, spray foam helps reduce drafts, improve energy efficiency, and keep indoor temperatures consistent.
What Makes Spray Foam Insulation a Safe and Effective Choice?
Spray foam insulation is one of the most effective options available for enhancing home comfort and reducing energy costs. But many homeowners also want to know about its safety—especially regarding indoor air quality and environmental impact.
Here are some key factors that make spray foam insulation both safe and effective when it’s installed professionally:
Air and Moisture Barrier to Improve Health
Spray foam insulation creates an airtight seal that keeps drafts out and blocks moisture. By keeping air and moisture out, spray foam prevents allergens, pollen, and dust from entering through gaps, which helps improve your indoor air quality.
This moisture barrier also reduces the risk of mold and mildew buildup—two common causes of respiratory issues and indoor air quality problems.
Mold Growth Due to Inadequate Insulation and Baffles
Higher R-Value Means Less Wasted Energy
Closed-cell spray foam has one of the highest R-values per inch of any insulation material, meaning it resists heat transfer better than other options.
This high insulation value keeps your home warmer in the winter and cooler in the summer, requiring less energy to maintain a comfortable temperature. With less energy use, fewer fossil fuels are burned to heat or cool your home, reducing your overall carbon footprint.
Soundproofing and Structural Support
Spray foam insulation doesn’t just insulate—it also dampens sound and reinforces certain areas of your home. With its dense, rigid form, closed-cell spray foam reduces noise between rooms and from outside. It can also add strength to walls and floors, offering extra stability over time.
Health and Environmental Concerns of Spray Foam Insulation
While spray foam insulation offers excellent energy efficiency and comfort, some homeowners wonder about its health and environmental impacts. Here’s what to know:
Health During Installation
Spray foam installation involves mixing chemicals that release volatile organic compounds (VOCs) as the foam cures. These VOCs can cause temporary respiratory irritation if inhaled before the foam is fully cured.
At Ecotelligent Homes, we use ventilation fans and recommend that homeowners stay out of the home for at least 12 hours after installation to allow proper curing and air clearing.
Environmental Impact of Blowing Agents
Certain spray foams use high global warming potential (GWP) blowing agents that negatively impact the environment. To address this, Ecotelligent only uses closed-cell spray foam with a GWP of 1, significantly reducing its environmental footprint.
When installed by certified professionals, spray foam insulation is safe and provides lasting benefits. Next, we’ll share more about Ecotelligent’s process and the steps we take to ensure a safe, clean installation.
How We Ensure Safe Installation
At Ecotelligent Homes, safety and quality are our top priorities when installing spray foam insulation. Our team follows industry best practices to ensure that every installation is safe, effective, and durable.
Certified Installers with Specialized Training
Our installers are Spray Foam Alliance Certified, which means they have advanced training and meet strict standards for safe spray foam installation. This certification ensures that our team follows the latest safety protocols and maintains high standards for quality and professionalism.
Ventilation and Curing Protocols
During installation, we use high-powered ventilation fans to keep fresh air flowing through the space, which helps reduce VOCs and shortens the off-gassing period.
We also recommend that homeowners leave the house during and for 12 hours after installation to allow for proper curing and air clearing, following manufacturer guidelines.
Advanced Equipment and Quality Control
Ecotelligent uses advanced spray foam rigs that keep chemicals at the ideal temperature and ratio, ensuring consistent foam quality. By applying foam at lower pressure, we minimize off-gassing and improve safety.
Additionally, we apply a thermal and ignition barrier paint over the foam, which adds an extra layer of protection and meets fire safety standards.
By using certified installers, ventilation practices, and quality control measures, we ensure that spray foam insulation is both safe and effective. In the next section, we’ll compare spray foam insulation to other common types to see how it measures up in health, efficiency, and durability.

Comparing Spray Foam to Other Insulation Options
Spray foam insulation is often compared to other common types, like fiberglass and cellulose. Here’s how spray foam stacks up in terms of health, efficiency, and durability.
Fiberglass Insulation
Fiberglass insulation is widely used, but it can release small glass particles into the air, which can irritate the skin, eyes, and respiratory system. Unlike spray foam, fiberglass does not create an airtight seal, which allows air leaks and reduces energy efficiency over time.
Cellulose Insulation
Made from recycled paper, cellulose is an eco-friendly option with fewer health concerns. However, it can settle and lose effectiveness, especially in moist environments. Spray foam, in contrast, maintains its form, resists moisture, and provides a continuous barrier that prevents air leaks and helps control humidity.
Spray foam insulation’s airtight seal, moisture resistance, and durability make it a top choice for Michigan homeowners, especially in areas prone to drafts or moisture issues. Next, we’ll discuss when spray foam might not be the ideal choice and suggest some alternatives.
When Spray Foam Insulation Might Not Be Recommended
Spray foam insulation is a versatile and effective option, but there are situations where it might not be the best fit for every home.
Older Homes with Moisture Control Needs
In older homes with existing moisture issues, additional steps may be required before installing spray foam insulation. Moisture trapped in walls can lead to mold or wood decay, so addressing any current moisture issues is critical.
In these cases, we might recommend pairing spray foam with other moisture control strategies or exploring alternatives.
Certain Attic or Wall Structures
In cases where walls or attic spaces are difficult to access or lack ventilation, we might suggest using a different type of insulation. Spray foam requires professional application and curing space, so it may not be suitable for structures without adequate ventilation or space for air circulation.
If spray foam insulation isn’t a fit, Ecotelligent Homes offers other insulation options, such as cellulose or dense-pack fiberglass, to ensure every home can improve its energy efficiency safely.
Conclusion: Is Spray Foam Insulation Right for Your Home?
While spray foam insulation is safe and effective for most homes, it’s essential to work with a knowledgeable installer who follows strict safety standards.
