Does anyone know if sound control underlayments (homosote or cork) need to also be FloorScore rated for this credit? Technically, it's part of the flooring system and we are trying for MRc6 but I cannot find a Floorescore Cork underlayment.

I would say that it has to comply, but remember it doesn't have to be FloorScore certified. It simply has to show compliance with CA 01350 requirements - so hopefully that opens up your options a little.

From my experience, I usually do not include underlayments. However, I agree with Josh in that you could still seek to meet the IAQ requirements for adhesives, etc.
