What is Spray Polyurethane Foam (SPF)
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.
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. As a result spray polyurethane foam is used in a wide variety of applications including, but is not limited to:
- 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. Spray Foam is durable, maintains physical properties over time, contributes little to the waste stream, and in a single product 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
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.
- SPF reduces drafts and increases comfort.
- SPF helps maintain a comfortable, constant, temperature throughout the building, from room to room and floor to floor.
- 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.
- 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.
- SPF helps conserve energy, reducing CO2 emissions.
- SPF contributes LEED credits for sustainable, green construction.
- SPF can help reduce structural damage caused by high winds.
- SPF contains no formaldehyde or ozone depleting substances.
Little Product... BIG Benefits!
Spray Polyurethane Foam insulation is rigid, lightweight, flexible, wind resistant, and effective in extreme temperatures and weather conditions. SPF insulation has the highest R-value per square inch of any commercially available insulation material.
The building envelope is a system of construction components which protect against the uncontrolled movement of: heat, air, and moisture.
The true performance of your building envelope cannot be measured with the R-value of the insulation alone, but must also consider air movement, moisture control, health, safety, durability, comfort, and energy efficiency.
This is true whether your building is commercial, residential, or multifamily: SPF addresses all these needs in both new construction and improvements to existing structures.
