Closed-Cell Spray Foam

Learn more about FB Spray Foaming insulation options

One of the types of spray foam we offer is closed-cell spray foam insulation.

Closed-cell spray foam insulation is a type of insulation material that is commonly used in both residential and commercial applications. It is made up of a mixture of polyol resin and isocyanate, which, when combined, react and expand to create a dense, rigid foam.

Closed-cell foam is denser and offers a higher R-value compared to open-cell foam. It provides better moisture resistance and acts as an effective vapor barrier. Closed-cell foam is often used in exterior applications such as roofs and foundations.

Choosing closed-cell spray foam insulation is beneficial because:

  • Achieves an air and vapour barrier
  • Mold resistant – using waterproof foam
  • Has the highest R-values per inch
  • Environmentally friendly option
  • Specially formulates to uneven surfaces
  • Adds additional strength to existing structures
  • Seals out radon gases
  • Ideal for use in basements, exterior structure walls, attic space, under foundation slabs
  • Comes with a 15-year warranty

Structure and Properties

Closed-cell foam insulation is composed of tiny cells that are sealed or closed, hence the name “closed-cell.” The cells are filled with a gas, which contributes to the foam’s structure and insulating properties. The closed-cell structure gives the foam its rigidity, making it resistant to air and moisture coming in.

Insulating Performance

Closed-cell spray foam insulation offers excellent insulating performance. It has a high R-value, which is a measure of its thermal resistance. The R-value of closed-cell foam is typically higher than that of other insulation materials, such as fiberglass or open-cell foam. This means that it provides better resistance to heat transfer, helping to keep indoor spaces warm in the winter and cool in the summer.

Application Process

The application of closed-cell spray foam insulation requires professional expertise. It is installed by trained insulation contractors using specialized equipment. The foam is sprayed onto the desired surface, it expands and then adheres to create a seamless insulation layer. It cures and hardens quickly, forming a durable, long-lasting insulation barrier.

Closed-cell spray foam insulation is an incredibly effective, versatile option for insulating residential and commercial buildings. Its superior insulating properties, moisture resistance, air barrier capabilities, and structural support make it a popular choice among homeowners and professionals seeking durable, energy-efficient insulation solutions!
