What is the maximum height for each timber system?

Current practical limits: Timber frame is typically used up to 6–7 storeys (platform frame method). CLT has been used up to 18 storeys (Mjøstårnet, Norway — hybrid CLT/glulam) and 10–12 storeys in pure CLT.

Current practical limits: Timber frame is typically used up to 6–7 storeys (platform frame method). CLT has been used up to 18 storeys (Mjøstårnet, Norway — hybrid CLT/glulam) and 10–12 storeys in pure CLT. Glulam frames are not height-limited in the same way — they are used for single-storey long-span structures up to multi-storey frames. Regulatory limits vary by country; structural and fire engineering rather than material properties typically govern maximum height.

Why this matters

This question relates to Timber Frame vs CLT vs Glulam: Structural Comparison for Architects, which covers the broader topic in detail. Understanding this specific aspect helps architects, builders, and timber dealers make informed specification decisions.
