Are you tired of sky-high energy bills and uncomfortable temperature fluctuations in your home? If so, it may be time to invest in injection foam insulation. This insulation material has been around for several decades and has become increasingly popular due to its numerous benefits. The following will break down the top 10 benefits of injection foam insulation, including how it works, what it’s made of, and why it’s the best choice for your home.

What is Injection Foam Insulation?

Injection foam insulation is an insulation and air barrier that seals enclosed cavities such as existing walls against air movement. Unlike traditional insulation materials like fiberglass and cellulose, injection foam insulation never loses its shape and completely fills the cavity, filling in all of the gaps and cracks.

How Injection Foam Insulation Works

When insulation works, it impacts the conduction (heat transfer) and convection (airflow), which play huge roles in your home’s energy efficiency and comfort. Traditional insulations are resistant to heat that is transferred through conduction but still allow for air movement. This air leakage contributes to a critical source of energy loss and drafts coming in through the walls, windows, and outlets.

Injection foam insulation, on the other hand, prevents air movement and stops heat transfer. It creates an air-tight seal that protects your home from the elements and keeps it warm, dry, and comfortable.

What is Injection Foam Insulation Made of?

There are several manufacturers of injection foam insulation, but for the purpose of this article, we will focus on RetroFoam injection foam. RetroFoam insulation is a three-part resin injection foam designed to insulate enclosed cavities such as existing walls. As the resin mixes with a foaming agent and water, it creates RetroFoam insulation, which looks similar to shaving cream in its consistency. This consistency helps the material fill all of the nooks and crannies and work its way between wires and pipes.

How is Injection Foam Insulation Installed?

Injection foam insulation can be installed into existing walls without the need to remove the old fiberglass. If loose cellulose exists, the crews will remove as much of it as possible before injecting the foam insulation.

The actual installation process for injection foam insulation can vary depending on the home’s exterior. For homes with aluminum or vinyl siding, a piece is removed from the side of the home, and a hole is drilled into each stud cavity. Foam is then injected into the holes, and once the cavity is full, the holes are plugged with Styrofoam plugs, and the siding is replaced.

The Top 10 Benefits of Injection Foam Insulation

1. Energy Efficiency

One of the top benefits of injection foam insulation is its energy efficiency. Injection foam insulation provides superior insulation and air sealing capabilities, which helps to reduce energy consumption and lower energy bills. By preventing air leakage, injection foam insulation can save homeowners up to 50% on their energy bills.

2. Improved Comfort

Injection foam insulation also improves comfort in your home. By eliminating air leaks, you can enjoy a more comfortable temperature throughout the year. Plus, injection foam insulation is an effective sound barrier, reducing exterior noise and creating a quieter indoor environment.

3. Reduced Environmental Impact

Injection foam insulation is an eco-friendly insulation option. It is made from recycled materials and has a lower environmental impact than other insulation materials. Additionally, by reducing energy consumption, injection foam insulation helps to reduce carbon emissions and protect the environment.

4. Deters Moisture

Moisture can wreak havoc on your home, causing mold, mildew, and other damage. Injection foam insulation is an effective moisture barrier, preventing water from seeping through openings around pipes and vents. And unlike other insulation materials that need to be replaced when wet, injection foam insulation retains its properties and continues to provide insulation even if it gets wet.

5. Longevity

Injection foam insulation is a long-lasting insulation solution. Unlike traditional insulation materials that can lose their effectiveness over time, injection foam insulation is composed of powerful chemical products that perform exactly how they should for decades. Once installed, injection foam insulation stays in place and won’t sag or shift over time, even in extreme temperatures.

6. Easy Installation

Injection foam insulation is easy to install. Unlike other insulation materials that require extensive labor and disruption, injection foam insulation can be installed quickly and easily. A team of professionals will use a spray foam gun to spray the material on your desired area, and the insulation dries quickly.

7. Fire Resistance

Injection foam insulation is also fire-resistant, making it a safe choice for your home. Unlike other insulation materials that can ignite and spread flames quickly, injection foam insulation resists combustion and can help to protect your home in the event of a fire.

8. Pest Resistance

Injection foam insulation is also pest-resistant. Unlike other insulation materials that can attract insects and rodents, injection foam insulation is not an ideal food source or nesting material. This makes it a less attractive home for pests and helps to protect your home from infestations.

9. Increased Property Value

Injection foam insulation is a valuable investment in your home. By improving energy efficiency, increasing comfort, and reducing environmental impact, injection foam insulation can increase your home’s value and appeal to potential buyers.

10. Cost-Effective

Finally, injection foam insulation is a cost-effective insulation solution. While it may have a higher upfront cost than other insulation materials, injection foam insulation pays for itself over time by reducing energy bills and increasing property value.


Injection foam insulation is an excellent insulation solution for homeowners looking to improve energy efficiency, reduce environmental impact, and increase comfort in their homes. With its superior insulation and air sealing capabilities, moisture resistance, longevity, and other benefits, injection foam insulation is a valuable investment in your home.
