Is Your Home or Business Losing Energy? Spray Foam Insulation Might Be the Answer

Energy costs are rising, drafts are sneaking in through every crack, and your HVAC system seems to run constantly no matter what you do. If any of this sounds familiar, the problem might not be your equipment — it might be your insulation.

Most buildings lose a significant amount of conditioned air through gaps, cracks, and poorly insulated surfaces. The result is wasted energy, uncomfortable interior temperatures, and utility bills that never seem to go down. Spray foam insulation addresses all of these issues at once, making it one of the most effective upgrades available for both residential and commercial properties.

At Polo International, we specialize in high-performance spray foam solutions designed to seal and protect your building from the inside out. Here’s what you need to know about how it works and why it might be the right choice for your property.

What Is Spray Foam Insulation?

Spray foam insulation is a two-component material that expands on contact to fill gaps, cracks, and cavities throughout a structure. Unlike traditional insulation materials such as fiberglass batts or blown-in cellulose, spray foam creates an air barrier in addition to a thermal barrier — two functions that most insulation types handle separately, if at all.

According to the U.S. Department of Energy, the type and placement of insulation plays a significant role in a building’s overall energy performance. Spray foam consistently ranks among the highest-performing options available, thanks to its ability to conform to irregular surfaces and seal air leaks simultaneously.

There are two primary types of spray foam used in construction:

Open-Cell Spray Foam

Open-cell foam has a softer, more flexible structure. It expands significantly after application and is particularly effective at filling large cavities and irregular spaces. It provides excellent sound dampening and is commonly used in interior walls, ceilings, and floors. Open-cell foam is generally more cost-effective and works well in climate-controlled environments.

Closed-Cell Spray Foam

Closed-cell foam is denser and more rigid. It offers a higher R-value per inch, meaning it provides more thermal resistance in a thinner layer. It also acts as a vapor barrier, making it ideal for exterior walls, crawl spaces, basements, and roofing applications. Closed-cell foam can even add structural rigidity to the surfaces it’s applied to.

The right choice between the two depends on the specific area being insulated, local climate conditions, and your performance goals. Our team at Polo International’s spray foam services can assess your property and recommend the most effective solution.

Where Can Spray Foam Be Applied?

One of the major advantages of spray foam is its versatility. It can be used in virtually any part of a structure, including areas where traditional insulation is difficult or impossible to install effectively.

Attics and Rooflines

Attics are one of the most significant sources of energy loss in residential buildings. Heat rises, and without proper insulation at the roofline or attic floor, that heat escapes in winter and floods back in during summer. Spray foam applied to the underside of the roof deck creates a conditioned attic space that dramatically reduces thermal transfer and protects ductwork from extreme temperatures.

Walls — New and Existing

In new construction, spray foam can be applied to wall cavities before drywall is installed. In existing buildings, injection foam techniques allow insulation to be added without removing finished walls, making it a practical option for retrofits and renovations.

Crawl Spaces and Basements

These areas are prone to moisture intrusion and air infiltration. Closed-cell spray foam applied to foundation walls and crawl space ceilings helps control humidity, prevent mold growth, and keep cold air from rising into living spaces above.

Commercial Roofing Systems

Spray polyurethane foam (SPF) is widely used as a roofing system for flat and low-slope commercial roofs. A seamless layer of foam is applied directly to the existing roof surface, followed by a protective elastomeric coating. The result is a fully adhered, waterproof roofing system with built-in insulation. Our SPF roofing systems are a proven solution for commercial and industrial properties looking to extend roof life and reduce cooling loads.

Around Windows, Doors, and Penetrations

Gaps around window frames, door jambs, electrical outlets, and pipe penetrations are common sources of air leakage. Spray foam seals these areas permanently, eliminating drafts and improving overall envelope performance.

The Energy Efficiency Benefits

Air leakage is one of the most underestimated sources of energy waste in buildings. The National Renewable Energy Laboratory has documented how building envelope improvements — including advanced insulation — can significantly reduce a structure’s overall energy consumption. Spray foam addresses this directly by creating a continuous, airtight thermal envelope.

Here’s what that means in practical terms:

• Lower heating and cooling costs. When conditioned air can’t escape and outdoor air can’t infiltrate, your HVAC system works less to maintain comfortable temperatures.
• More consistent indoor temperatures. Rooms that were previously cold in winter or hot in summer become easier to regulate.
• Reduced HVAC wear and tear. Less runtime means less mechanical stress on your heating and cooling equipment, which can extend its lifespan.
• Improved humidity control. Closed-cell foam acts as a vapor barrier, reducing moisture infiltration that can lead to mold, rot, and poor air quality.

For urban and suburban properties, there’s an additional consideration. The EPA’s urban heat island research highlights how densely developed areas tend to retain more heat, increasing cooling demands on buildings. Reflective SPF roofing systems and well-insulated building envelopes can help offset that effect, reducing the energy burden on both individual properties and the surrounding grid.

Indoor Air Quality and Comfort

Energy efficiency is only part of the story. Spray foam also has a meaningful impact on the air you breathe and the comfort you experience inside your home or building.

When a building envelope leaks air, it also allows in dust, pollen, exhaust fumes, and other outdoor pollutants. Sealing the envelope with spray foam helps control what enters the building. According to ASHRAE Standard 62.1, managing ventilation and air infiltration is central to maintaining acceptable indoor air quality — and a tight building envelope is the foundation of that effort.

Additional air quality and comfort benefits include:

• Reduced allergen infiltration. Sealing the building envelope limits the entry of pollen, dust mites, and other airborne irritants.
• Noise reduction. Open-cell spray foam in particular provides excellent sound dampening, making it effective for interior walls between rooms or floors in multi-unit buildings.
• Elimination of cold drafts. Air sealing removes the uncomfortable drafts that often occur near windows, exterior walls, and floors over unconditioned spaces.

It’s worth noting that tightly sealed buildings benefit from proper mechanical ventilation to ensure fresh air exchange. Our team can discuss how spray foam installation integrates with your existing HVAC and ventilation systems.

Is Spray Foam Right for Your Property?

Spray foam insulation delivers strong results across a wide range of property types, but the best outcomes come from proper assessment and professional installation. Several factors influence the approach, including:

• The age and construction type of the building
• Current insulation levels and air sealing performance
• Local climate and typical temperature ranges
• Whether the project is new construction or a retrofit
• Specific goals, such as energy savings, comfort improvement, or moisture control

Properties that tend to see the most significant benefits include older homes with minimal insulation, commercial buildings with flat roofs, structures in hot or humid climates, and any building with a history of high utility bills or inconsistent temperatures.

Our clients consistently report lower energy costs, improved comfort, and greater satisfaction with their properties after spray foam installation.
