Is CLT suitable for multi-storey buildings?

Yes, CLT is used in buildings up to 18 storeys (the current tallest CLT building is Mjøstårnet in Norway at 85.4 m). For buildings above 4 storeys, CLT is typically combined with glulam columns and beams to optimise material use.

For buildings above 4 storeys, CLT is typically combined with glulam columns and beams to optimise material use. Fire regulations in most European countries permit CLT buildings up to 6–8 storeys with standard fire engineering; taller buildings require advanced fire strategies including sprinklers and encapsulation.
