Note

The fire resistance is only valid when wall is used as partition with only one side exposed to fire.

Attention: REI 90 (from inside) in Germany possible with 2x12,5mm gypsum plaster board type DF/gypsum fibre board

e.g. Cross laminated timer:
thickness 5-ply at least, surface layer at least 19mm
