HFO (Hydrofluoroolefin) insulation also known as fourth-generation spray foam insulation refers to spray foam insulation that uses HFOs as blowing agents. These blowing agents are transformed into the spray foam that is filled in every nook and cranny of buildings to achieve thermal insulation. HFO insulation can be applied in commercial or residential buildings to lower energy bills.
HFO is a chemical compound that is made from hydrogen, fluorine, and carbon, and it is being increasingly used as a blowing agent in place of HFCs (hydrofluorocarbons) in spray foam insulation in the U.S since 2021. This is because it is a climate-friendly blowing agent that does not emit harmful greenhouse gasses that deplete the ozone layer and contribute to global warming. HFO insulation is becoming a popular eco-friendly insulation option because of its low global warming potential (GWP) and zero ozone depletion potential (ODP).
HFO insulation can be applied in empty spaces or cavities making it ideal for insulating new constructions. It can be installed in attics, basements, roofs, ceilings, walls, between floors, and in HVAC ducts.
HFO is mildly flammable or non-flammable depending on which HFO compound is being used. HFO insulation uses HFO-1234ze is non-flammable which is non-toxic and non-flammable.
According to the Environmental Protection Agency (EPA), HFOs are considered non-toxic and inert. They do not contribute to the depletion of the ozone layer or global warming.
R32 is a mildly flammable and non-toxic HFC with low global warming potential. Due to its high thermal stability, it is used as a refrigerant in HVAC units such as split air conditioners for the transfer of heat.
HFO foam uses hydro fluoro-olefin (HFO) as a blowing agent due to its low environmental impact as it does not emit ozone-depleting gasses. The HFO blowing agent is mainly used in closed cell foam insulation in which it is enclosed in millions of closed cells.
To the untrained eye, the spray foam application process appears deceivingly simple. Just spray on the insulating foam. Let it cure. Cover with sheetrock. Job well done. Or is it? As a pioneering force in the field of spray foam insulation for well over two decades, AirSeal Insulation Systems knows that the analysis, planning and strategy surrounding a building envelope will directly affect the outcome of every job. The understanding of structural design, material application, modern technology and environmental factors all contribute to the effectiveness of an air barrier system. In other words? There’s a serious process involved, and it’s something we make a big deal about.
