Standard configuration

Note

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

Cross laminated timber:
Var. 00: thickness ≥ 78mm; 3-ply at least, surface layer at least 25 mm
Var. 01: thickness ≥ 94mm; 3-ply at least, surface layer at least 30 mm
