Plywood vs particleboard
Plywood is built from cross-laminated wood layers, which gives it strength and screw-holding power. That matters when cabinets are shipped, installed and loaded with dishes for years.
| Factor | Plywood (ECG) | Particleboard |
|---|---|---|
| Material | Cross-laminated wood veneers | Compressed wood particles and resin |
| Screw holding | Strong, holds after re-tightening | Weaker, can strip |
| Water exposure | More tolerant of a leak | Swells when wet |
