The Complete Guide to Plywood: Types, Uses & Buying Tips
What is Plywood?
Plywood is an engineered wood panel made by bonding multiple thin wood veneers (layers) with adhesives. Its cross-grained structure (odd-numbered layers like 3-ply or 5-ply) provides exceptional dimensional stability, making it ideal for furniture and construction projects.
