Spray polyurethane foam (SPF) insulation provides excellent thermal insulation and air sealing for residential, commercial, and industrial applications on a variety of substrates. When properly installed, SPF can help reduce air leakage, improve energy efficiency, and contribute to indoor comfort. Depending on the product type and application, SPF may also help manage moisture, reduce noise, and provide long-term performance.

Key benefits of SPF insulation include:

  • Thermal insulation and energy efficiency
  • Air sealing and reduced air leakage
  • Improved indoor comfort
  • Moisture management
  • Long-term performance and durability

The following sections highlight some of the key benefits of SPF insulation.

Lowers energy use and cost

SPF insulation provides thermal insulation and air sealing, helping to reduce the transfer of heat and air movement through the building envelope. By limiting air leakage and improving thermal performance, SPF can help reduce the energy needed to heat and cool a building. In some building designs and applications, improved energy performance from SPF insulation may allow for smaller heating and cooling equipment, depending on the building design and applicable code requirements.

Reduces air infiltration

Air can enter a building through gaps, cracks, and other openings in attics, foundations, exterior walls, and other parts of the building envelope. Air leakage can reduce energy efficiency and allow dust, pollutants, noise and moisture to enter. When properly installed, SPF insulation can help reduce air infiltration by creating a continuous air barrier for building assemblies, helping to improve overall performance.

Insulates irregular spaces and complex building features

SPF insulation can be installed in a wide range of building assemblies and can conform to irregular designs and shapes, such as bay windows, angled walls, curved or arched ceilings. SPF is applied in place and expands to fill gaps and voids, creating design flexibility, improved energy efficiency, and functional space.

Improves comfort

SPF insulation creates a tighter barrier around buildings, which can reduce the infiltration of pollen, dust, allergens and other contaminants. Depending on design, installation, and other building conditions, SPF insulation can help prevent moisture and condensation throughout the building envelope, reducing the potential for mold and mildew growth. In addition, SPF insulation can dampen exterior noise by limiting air pathways in building assemblies, contributing to a quieter indoor environment.

Energy Efficiency Advantages of SPF

A major reason to use SPF is for energy efficiency. The energy savings obtained by using SPF in homes and buildings is significant enough that the purchase and use of insulating foam sealant products may qualify for utility rebates, tax credits, and green certification.

Local Utility Rebates

Many local utility companies offer rebates for energy efficiency upgrades, including SPF insulation. Check with your local utility provider to see if you qualify.
