Common pressure issues in a spray foam system are often indicated by abnormal foam colors, strange foam textures, and imbalanced pressure gauge readings.
In this blog post, we unpack what hydrofluorocarbons, or HFCs, and hydrofluoroolefins, or HFOs, are; why the EPA is suggesting the change from HFC to HFO in spray foam insulation; and which US states already require the transition.
The latest EPA guidelines are calling for a transition from hydrofluorocarbon – or HFC – in spray foam blowing agents to hydrofluoroolefin – or HFO.
To better understand HFCs, HFOs, and blowing agents, we first need to examine spray foam chemistry.
