The Role of Subfloors in Sports Wood Flooring Performance

1. Types of Subfloors:
   • Plywood, OSB, and concrete bases.
   • Elastic layers (rubber, foam, or cork).
2. Design Considerations:
   • Load distribution for heavy equipment (e.g., stage rigging).
   • Thermal expansion gaps in large venues.
3. Failure Modes:
   • Subfloor moisture causing adhesive breakdown.
   • Case study: A collapsed floor due to improper subfloor support.

Conclusion: Subfloors as the foundation of durability.
