US WHITE HOUSE RECOGNIZES HFO AS POLYURETHANE SPRAY FOAM INSULATION BLOWING AGENT FOR ITS LOWER CLIMATE IMPACT

An American Polyurethane spray foam insulation producer has been hailed by the White House for its commitment to use low GWP HFO-1234zeE as the blowing agent for its entire production line by 2016, as part of the US Climate action Plan.

HFO-1234zeE has a GWP of 1 (IPCC value), is non flammable and is not classed as Volatile Organic Compound. It provides PU foam with an excellent insulating value.

Spray foam insulation is mainly applied on building roofs and in private house attics.   Spray foam is used to insulate, provide air sealing and improve structural strength in buildings. The insulation potential of spray foam is dependent upon the insulating gas in the cells of the polyurethane foam. In addition to the insulation performance, polyurethane foams used for insulation require inherently superior dimensional stability and resistance to fire.
