Block board uses solid wood strips bonded together as the core, faced with veneer plies on both sides — delivering superior rigidity for long spans and better screw-holding at edges than MDF or particle board.
| Property | Block Board | Plywood | MDF |
|---|---|---|---|
| Core Material | Solid wood strips | Cross-grain veneer | Wood fibre |
| Rigidity (long spans) | Excellent | Good | Sags under load |
| Screw-Holding at Edges | Good | Good | Poor |
| Weight | Light (hollow core feel) | Heavier | Medium |
| Surface for Painting | Good (veneer face) | Good | Excellent |
| Long-Span Shelving | Best choice | Good | Not recommended |
| Door Shutters | Traditional choice | Possible | Too heavy |
| Thickness | Core | Face | Sheet Size | Grade |
|---|---|---|---|---|
| 19mm | Solid wood strips (softwood/hardwood) | Veneer both sides | 8×4 ft | BWR / BWP |
| 25mm | Solid wood strips (hardwood) | Veneer both sides | 8×4 ft | BWR / BWP |
Door specification: 35mm flush doors typically use block board core. For the panel material used in door shutters (not the complete door), 19mm block board is standard — it provides the rigidity and edge-screwing ability that flush door hardware requires.
