Spray foam insulation is a high-performance insulation system made by combining two liquid components on-site to create an expanding foam. Once applied, the foam quickly expands to fill gaps, cracks, and hard-to-reach areas, creating an effective barrier against air leakage and energy loss. This process is what makes spray foam insulation different from traditional materials like fiberglass insulation or blown cellulose.

Because it is applied in liquid form and expands during installation, spray foam insulation can seal spaces more completely than many other insulation products. At Minnesota Spray Foam and Coatings, our trained technicians use specialized equipment to mix and apply the materials properly, ensuring a consistent, durable insulation layer designed for long-term performance.

Our closed-cell spray foam insulation features tightly sealed cells that help create a strong air barrier and moisture-resistant barrier. It absorbs very little water, adds rigidity to building assemblies, and delivers a high R-value per inch, making it an excellent choice for both residential and commercial insulation projects. Closed-cell spray foam is ideal for applications where strength, energy efficiency, and moisture control are especially important.

Whether you are insulating a home, garage, pole building, basement, crawl space, wall, ceiling, or industrial space, closed-cell spray foam provides long-lasting performance and helps improve energy efficiency, indoor comfort, and building protection.
