Bonjour Norman,

You also have in Europe a range of ETICS (external thermal insulation
system) in natural insulations which can be plastered /
rendered such as wood fibre board (depending on the fabricant most but
not all contain 15% synthetic binder) or cork,

Gutex WDVS Thermowall  on wood frame or masonry  wood fiber board

Pavatex Diffutherm  on wood frame or masonry  wood fiber board

Inthermo   wood fiber board

Liège Spécial Façade - SNIC  cork

and even foamed cement panels

Xella/Ytong Multipor     for masonry
