Hi Bohdan,
yes, it's quite restrictive to have to comply to specified components in
the certificate. In order to have more allowable variations, we asked
for an expert opinion. It says that other lime or clay plasters are
okay. Right now, there is just the German version (attached). But we
want to translate it into English soon.
As far as I know in Germany (and Europe) there is no general fire
resistance standard given to a render layer. Correct me, if I'm wrong.
(There are for gipsum boards.)
Best regards
Benedikt
