Sheet material sizes & board thicknesses
Plywood, MDF, OSB, plasterboard, fibre cement, HPL and melamine board formats and thicknesses, with sheet weight guidance.
Reference formats include 2440 × 1220 mm and 3000 × 1500 mm plywood products. Format availability depends on the material, thickness, décor and supplier; a listed size does not confirm stock in Cyprus, Greece or the UK.

Choose declared bond/exposure class and structural grade where required. “Marine” does not make exposed edges maintenance-free. The 3000 × 1500 mm format is documented for selected birch plywood products (e.g. PERI film-faced panels); it is not available in every grade or thickness. Confirm the exact combination with the supplier.
