Hi all,
I think this might have already been clarified somewhere, but I cannot find an official answer. Apologies if I might be ripetitive.
Seemly, it's quite impossible to find NAUF plywood in Ireland and UK. All suppliers and manufacturers seem to follow European E1 Standard for UF emissions. I understand that timber in general can have UF and I have to look for NAUF, but does that mean that I have to totally refuse any E1 plywood or forget about the credit point if suppliers cannot confirm NAUF?
I have already checked the LI 10250...
"E1 yes or no"?

Exterior grade plywood contains phenol formaldehyde (not urea formaldehyde), so if it is exterior grade plywood, it is acceptable for NAUF. I hope that may help.

Looks like the European classification E1 does not restrict Urea-Formaldehyde; E1 is just a maximum formaldehyde level. So possibly E1 could contain UF.
