What is the difference between timber frame and CLT?

Timber frame uses lightweight studs (typically 38–89 mm wide C24 timber at 400–600 mm centres) with panel sheathing to create load-bearing walls and floors. CLT (Cross-Laminated Timber) uses solid engineered panels (typically 100–300 mm thick) made from layers of timber boards glued at right angles.

Timber frame uses lightweight studs (typically 38–89 mm wide C24 timber at 400–600 mm centres) with panel sheathing to create load-bearing walls and floors. CLT (Cross-Laminated Timber) uses solid engineered panels (typically 100–300 mm thick) made from layers of timber boards glued at right angles. Timber frame is lighter, cheaper for low-rise, and faster for repetitive housing. CLT provides greater mass, better acoustics, higher fire resistance, and enables taller buildings (up to 18+ storeys).
