WHAT IS SPRAY FOAM® INSULATION?
Spray foam insulation is a type of insulation material that is applied as a liquid and then expands into a foam to fill gaps, cracks, and voids in walls, ceilings, and other surfaces. It is composed of two main components, isocyanate and polyol resin, which are mixed together at the application site using specialized equipment.
Once sprayed, the foam expands rapidly, adhering to surfaces and forming a continuous layer of insulation that provides an effective thermal barrier. Spray foam insulation comes in two main types: open-cell and closed-cell. Open-cell foam is lighter and more flexible, offering some soundproofing benefits, while closed-cell foam is denser and provides a higher R-value per inch, making it more effective at insulating against heat transfer.
Spray foam insulation offers several advantages, including excellent thermal performance, air sealing properties, and versatility in application. It can help improve energy efficiency, reduce heating and cooling costs, and enhance indoor comfort. Additionally, spray foam insulation can contribute to moisture control and can help prevent the growth of mold and mildew in buildings.
It’s easy to confuse “injection foam” and “spray foam,” but there is a difference. Spray polyurethane foam (SPF) is an innovative foam plastic substance that is sprayed onto an open surface in paint-like form and then expands to create an insulating barrier against wind and outside temperatures. Once the insulation sets, it expands to create an insulation barrier against extreme temperatures and moisture. On the other hand, injection foam is used for existing walls that are closed.

THE SCIENCE BEHIND SPRAY FOAM
Spray foam insulation, a versatile and innovative insulation material, is backed by scientific principles that underscore its effectiveness in enhancing building performance.
Here’s a breakdown of the scientific aspects:
- Expanding Properties: Spray foam insulation quickly expands upon application, filling gaps and creating a seamless layer of insulation without additional support.
- Thermal Performance: Closed-cell spray foam offers high R-values, indicating superior resistance to heat flow compared to traditional insulation materials like fiberglass.
- Air Sealing and Moisture Control: Spray foam acts as both insulation and an air barrier, sealing off drafts and preventing moisture infiltration, reducing the risk of mold growth.
- Structural Integrity: Beyond insulation, spray foam can strengthen building structures by adhering to substrates and distributing loads more evenly.
- Environmental Considerations: While effective, spray foam formulations may contain blowing agents with high global warming potential, prompting the development of eco-friendly alternatives.
In conclusion, spray foam insulation emerges as a scientifically validated solution for optimizing building performance. Its expanding properties, superior thermal performance, air sealing capabilities, structural enhancements, and ongoing environmental considerations collectively position it as a preferred choice in modern construction practices. By leveraging the science behind spray foam insulation, builders and homeowners alike can achieve significant improvements in energy efficiency, indoor comfort, structural resilience, and environmental sustainability, contributing to a more sustainable and comfortable built environment for generations to come
