Green Building Q&A: 13 reasons why foam fails?

1) toxicity is relative, and the chemicals involved are NOT a particularly high risk, but riskier than cellulose I s'pose. 2)Global warming potential is primarily a function of the blowing agents used. It' pretty much a non-issue for open cell foam, and there are some closed cell foams out there that are water -blown, no HFCs, but it's an issue. 3)The fire hazards is highest during incorrect installation when 2lb foam is applied too thick all at once. Once installed behind ignition barriers the risk isn't very different than with some traditional insulating materials. 4)Hypersensitive? Not so much. Yes, there are specs to be followed, but it doesn't take a team of rocket scientists with instrumentation to get it right. Most blowing equipment heats the A & B side chemicals to a fairly tight temperature range to get a good mix and consistent results, but even the 2-part non ...

Just in time for my retrofit, some soul-searching about #InsulatingFoams. Does it matter they're not all the same? [link]
