New HFO blowing agents for spray foam will make it over 1,000 times less harmful to the climate

...global warming potential (GWP) that was over a thousand times worse than carbon dioxide as a green house gas. As a result of the 1990 Montreal Protocol to ban ozone-depleting gases - mainly chlorofluorocarbons (CFCs) - hydrofluorocarbons (HFCs) took their place as the blowing agents for foam insulation. That halted o...

...Global Warming Potential (GWP) of Methane is a cause for concern. One not so promising source is from fracking, which is a process for extracting natural gas from shale rock. It involves pumping water and chemicals into shale rock at very high pressure causing the release of methane gas. While this was at first see...

...global warming must be limited to 1.5 degrees Celsius, otherwise the climate change consequences will be irreversible. To do this, a report by the Intergovernmental Panel on Climate Change (IPCC) from 2018 mentions the need to reduce anthropogenic CO2 emissions by 45% compared to 2010. Buildings are the biggest sourc...

Spray Foam Insulation - Is it Good or Toxic & Dangerous?
Insulation and soundproofing

Is spray foam insulation a good choice for your home? Or a toxic recipe for disaster?

...Global Warming Potential. Global Warming Potential, or GWP, is a measure of how much heat-trapping potential a substance has, compared to carbon. A GWP of 1430 means that a given unit of a substance is that much worse than carbon as a heat trapping gas when released into the atmosphere. The new HFO (hydrofluoroolef...
