It’s safe to say that most homeowners would prefer to avoid paying unnecessary utilities, maintenance, and repair expenses on their homes. It is also why we generally avoid leaving faucets running unattended, the lights on in vacant rooms or keeping doors open when the air conditioner is on.

Why is traditional home insulation often not enough?

Without realizing it, you could still be leaking up to 50% of your cooled air while allowing humidity and airborne particles to pollute your home. Many homes in the U.S., particularly those built over 20 years ago, have not replaced their original fiberglass batt insulation, which deteriorates over time, causing air leaks and leaving homes under-insulated and more vulnerable to extreme weather, and temperature changes, noise, and humidity.

A better choice: Spray Foam Insulation

Spray foam is more resistant to heat transfer than other insulation materials. It consistently and significantly outperforms traditional insulation materials. Simply put when heat can’t travel from outside through your walls, roof decks, or floor then your house stays at the temperature you want it. Spray foam insulation is one of the most effective ways of creating a barrier that keeps your cool air in and hot, humid air and pollutants out.

There are different kinds of spray foam insulation available,

Closed Cell Spray Foam

Applied within the walls and roof of your home, closed-cell spray foam works as a vapor barrier that creates a seal to prevent humid air from moving through the insulation and your house. This keeps humidity and moisture out. The Federal Emergency Management has rated closed cell spray foam insulation as a highly flood-resistant material. This advanced insulation can maintain a flood barrier for your home for up to 72 hours and can help reduce the damage caused by hurricane winds. Closed-cell spray foam has the advantage of not only being waterproof but also significantly increasing the strength of the building to which is applied so making your roof and structure more resistant to hurricane-force winds and floods.

Open Cell Spray Foam

Applied in the same fashion, closed-cell spray foam is similar to closed-cell in terms of creating an effective barrier that creates a seal to prevent humid air from moving into your house. Open-cell spray foam is less resistant to water and wind damage than Closed-cell spray foam.

The 5 Benefits of Spray Foam Insulation

  1. Increased Comfort– One of the most sought-after benefits of spray foam insulation is that keeps your house comfortable by preventing temperature fluctuations. It promotes a consistent climate as it creates an air-tight seal to protect your home from external elements like heat and humidity. Since spray foam sticks to the surfaces of your interior walls and attic, it creates a seal that keeps the hot, humid air out and the cool, clean air inside.
  2. Improves Indoor Air Quality – Spray foam helps to minimize indoor allergens such as dust, mold, mildew, pollen, and other pollutants. These enter your home through the walls and can affect air quality. Also, insects and rodents are not attracted to spray foam as this is not an ideal food and nest for them. If you suffer from respiratory issues consider spray foam as this is a non-toxic option that maintains better indoor air quality.
  3. Increased Savings– spray foam’s efficacy at keeping houses insulated helps to improve the home’s carbon footprint as it reduces the consumption of energy needed to cool the spaces. This results in a reduction of up to 50% in cooling bills.
  4. Protection from extreme weather – Professionally applied closed cell spray foam serves to reinforce the strength of the structure of your home. This adds measurable resistance to the wind uplift forces experienced in a strong hurricane. This helps to keep your home safe and intact in storms. Spray foam also acts as a barrier to water and flooding so keeping the interior of your home dry and safe in extreme weather conditions.
  5. Longevity – Spray foam insulation is often described as the last insulation you will ever need to install in your home. It has been proven to be effective for very long periods of time (over 80 years) and will often outlast the house itself.

This product is added to spray foam insulation to protect it from igniting when exposed to fire. With a Class One Fire rating, our spray foam has retardant and self-extinguishing properties that better protect homes and structures from a fire.


Made of fiberglass, this is commonly used and versatile; however, spray foam insulation is usually a better, more advanced option to achieve the superior benefits of quality insulation.


Fi-Foil is a thin blanket made out of various layers of aluminum, thermo-foam, and polypropylene. It reflects and absorbs heat to cool the structure better. It must be installed correctly to achieve energy savings.


This is another popular form of insulation sprayed directly into walls and attics that uses flexible and expanded foam. It is a good solution for tight or hard-to-reach spaces. The final product reveals open cells in the material (hence the name).


Sprayed directly into walls and attics, this very dense foam seals against air movement and provides exceptional thermal insulation and long-term value for the home or building owner. Made from recycled plastic and rapidly renewable soy oils, it is among the most innovative products in the industry. Besides providing excellent temperature and air quality control, it has proven efficacy in protecting structures from wind, water, and insects.
