What are the maximum panel sizes for CLT?

Standard CLT panels are manufactured up to 3.5 m wide and 16 m long, with thicknesses from 60 mm to 400 mm (typically 3, 5, 7, or 9 layers). Transport constraints often limit practical panel size to 3.0 × 12.0 m for road delivery in Europe.

Standard CLT panels are manufactured up to 3.5 m wide and 16 m long, with thicknesses from 60 mm to 400 mm (typically 3, 5, 7, or 9 layers). Transport constraints often limit practical panel size to 3.0 × 12.0 m for road delivery in Europe. Larger panels can be delivered by special transport arrangement but at increased cost. Panel weight ranges from approximately 50 kg/m² (100 mm thick) to 200 kg/m² (400 mm thick).
