Spray polyurethane foam is the king of building materials for multitasking. For moisture it can provide high levels of R-Value, while providing air barriers and assistance in moister control in buildings. 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.
  

What are the benefits of SPF?
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

Other benefits include...

• Closed cell SPF adds structural strength and glues a building together, thereby making it more resistant to racking events, such as hurricanes and high winds.
• SPF reduces noise from outside by air sealing the building.
• Closed-cell SPF can provide an added barrier against water intrusion.

Comfort:

• SPF reduces drafts and increases comfort.
• SPF helps maintain a comfortable, constant, temperature throughout the building, from room to room and floor to floor.

Health:

• SPF assists in improving indoor air quality.
• SPF reduces the infiltration of outside air pollutants and soil gases.
• SPF can reduce moisture condensation and mold growth within the building walls and roof.
  

Value:

• Excellent insulation efficiency of SPF can reduce heating and cooling usage dramatically.
• HVAC equipment can be down-sized, thereby reducing construction costs.
• SPF will not sag or settle.
• SPF can eliminate the need for separate housewrap and vapor retarders.
  

Is Spray Polyurethane Foam Safe?

Yes, cured spray polyurethane foam is relatively inert and studies indicate that SPF does not release toxic gases or leach harmful chemicals into the soil.

Applicators and other persons within a close proximity to the spray operation could be exposed to fumes and spills beyond OSHA and NIOSH requirements. Precautions should be made for applicators, helpers and building occupants to be protected from these fumes, mists and spills. Typically for the applicator this would include respirator, solvent resistant gloves and protective clothing. The zone where protective equipment is required can vary depending on the amount of open space and free ventilation. For example on a roof top, outside of a few feet the fumes dissipate rapidly, while in an enclosed room, fumes and mists can build. Each job should be assessed and a safety plan developed specific to the application.

Not only is spray foam insulation green, it's versatile. It functions well as a barrier to airborne sound and comes with one of the highest fire resistances available in similar products. Pest and rodents won't do any damage because the insulator has no nutritional value to them. It's water resistant, and flexible enough to allow some movement of the building structure. Finally, it produces no toxic vapors after it's applied.
