What is Spray Polyurethane Foam?

Spray polyurethane foam, commonly referred to as SPF, is a spray-applied insulating foam plastic that is installed as a liquid and then expands many times its original size. It can be used over existing metal roofs, granulated modified roofs and built-up roofs (Mod/Bit). Spray polyurethane foam can be adjusted and have many different physical properties depending on the use desired.

For example, the same basic raw materials that can make insulation foam semi-rigid and soft to the touch also creates high density roofing foam that is resistant to foot traffic and water. Specialized equipment is used to apply the spray polyurethane foam and proper technical training is important in order to get the best results.

For roofing, spray polyurethane foam insulates and eliminates thermal bridging through fasteners or gaps in decking while providing a long-lasting roofing system that has a life that can be extended by re-coating or recovering in an average of > 10 – 15 years. As a result spray polyurethane foam is used in a wide variety of applications including, but is not limited to:

  • Roofing
  • Air barriers
  • Commercial and residential insulation in walls, ceilings, attics and basements
  • Industrial insulation for pipes and tanks, cold storage facilities, freezers, walk-in coolers, and climate controlled buildings such as produce storage and clean rooms
  • Flotation for boats, ships, barges, floating docks, etc.
  • Higher density spray polyurethane foam has been used to increase the structural strength of wings in airplanes.

SPF is environmentally friendly, contains no formaldehyde or ozone depleting chemicals, saves energy* and reduces the use of fossil fuels, thereby reducing global warming gases. It also assists in providing good indoor air quality, requires less energy to produce than the leading insulation, and reduces the amount of energy required to transport and install it.

SPF is durable, maintains physical properties over time, contributes little to the waste stream, and in a single product (depending on the formula and project) can take the place of three-four other products, including insulation, air barriers, sealants, vapor retarders, and weather barriers.
*SPF reduces energy use in the following ways:

  • Has high R-value per inch (open-cell 3.5 per inch and closed-cell 6.0 per inch)
  • Eliminates air infiltration
  • Helps control moisture and condensation
  • Reduces convective currents in walls and attics
  • Eliminates wind washing
  • Effective at low and high temperatures
  • Provides the correct environment so that the ventilation system performs more efficiently
