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. Polyurethane insulation are usually cheaper than installing foam boards. These applications also usually perform better since the liquid foam moulds itself to all of the surfaces and provides seamless thermal protection.
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
- Marine and Industrial Insulation
- Roofing - Commercial and Domestic
- Industrial insulation for pipes and tanks, cold storage facilities, freezers, walk-in coolers, and climate controlled buildings such as produce storage and clean rooms
- Polyurethane cavity wall insulation
- Air barriers
- 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
- Insulation for the agricultural industry (broiler houses, piggeries, wineries and fruit storage).
