Why Choose Spray Foam Insulation for Your Home’s Efficiency

Energy efficiency has become a significant factor in managing our homes and buildings. One of the most effective ways to improve energy efficiency is through proper insulation. Among many insulation materials available, spray foam has gained popularity due to its numerous advantages. In this blog, we will explore energy-efficient spray foam insulation and its benefits to homeowners and builders.

What is Spray Foam Insulation?

Spray foam insulation (SFI) is a polyurethane-based insulating material applied as a liquid and quickly expands into a solid foam, filling gaps and sealing spaces in walls, roofs, and floors. It comes in two main types: open-cell and closed-cell spray foam. Open-cell foam is softer, lighter, and more flexible, while closed-cell foam is more rigid, dense, and has a higher R-value (a measure of thermal resistance).

Energy Efficiency Benefits of Spray Foam Insulation

1. Improved Thermal Resistance

One of the main advantages of spray foam insulation is its high R-value. Closed-cell foam has an R-value of around 6.0 to 7.0 per inch, compared to fibreglass insulation’s R-value of approximately 3.0 to 4.0 per inch. This means that a thinner layer of spray foam can provide the same insulation as a thicker layer of fibreglass, making it a more efficient insulating material.

2. Air Sealing

Air leakage through gaps and cracks in a building’s envelope is a significant factor in energy waste. Spray foam insulation expands upon application, effectively sealing these gaps and cracks, reducing air infiltration, and improving energy efficiency. By minimizing air leakage, spray foam insulation helps maintain a consistent indoor temperature, reducing the strain on heating and cooling systems and lowering energy costs.

3. Moisture Control

Moisture infiltration can cause energy loss and contribute to the growth of mould and mildew, which can negatively impact indoor air quality and occupants’ health. Spray foam provides a moisture barrier, preventing water infiltration and associated problems. Closed-cell spray foam is especially effective at preventing moisture intrusion due to its high density and impermeability.

4. Enhanced Structural Strength

Closed-cell spray foam insulation has the added benefit of increasing a building’s structural strength. It adheres firmly to the surfaces it’s applied to, reinforcing walls and roofs and making them more resistant to wind and other external forces. This added strength can help protect a building from damage during extreme weather events, reducing repair and maintenance costs in the long run.

5. Noise Reduction

Spray foam insulation is also an effective sound barrier. Its dense composition and ability to fill gaps and cracks help reduce noise transmission between rooms and from the outside environment. 

6. Longevity and Durability

Spray foam insulation is highly durable and can last for the life of a building, reducing the need for replacement and maintenance. Its resistance to moisture and mould growth also contributes to its longevity, providing energy-efficient insulation for many years.

Cost-Effectiveness of Spray Foam Insulation

While spray foam insulation may have higher upfront costs than traditional insulation materials such as fibreglass, its long-term benefits make it a cost-effective choice. The energy savings from spray foam insulation can offset the initial installation costs over time. Additionally, the reduced need for maintenance and repairs due to its durability and moisture resistance can further contribute to cost savings.


Energy-efficient spray foam insulation offers numerous benefits, including improved thermal resistance, air sealing, moisture control, structural strength, noise reduction, and longevity. While the initial investment may be higher than other insulation options, the long-term energy savings and reduced maintenance costs make it a wise choice for homeowners and builders looking to improve energy efficiency and comfort in their buildings.
