 So I look at when Johns Manville came out with formaldehyde-free fiberglass insulation, what was that, 10 years ago? Within the first month of them bringing this out, they had a buy full-page ad in the trade publication saying, we didn't do this for any health reasons. We did this because it's a better resin. It's more affordable. It's more sustainable. But don't worry. Formaldehyde's fine.
