This treatment process contributes to the plywood’s enhanced durability, especially in outdoor applications exposed to varying weather conditions.
2. Chemical Treatment
Chemicals like chromated copper arsenate (CCA) or alkaline copper quaternary (ACQ) are commonly used to treat the wood. These chemicals penetrate the wood fibers, creating a protective barrier that resists decay and rot. The treatment process is crucial in ensuring the longevity of treated plywood in environments where exposure to moisture is a concern.
3. Layered Construction
Similar to marine plywood, treated plywood also consists of multiple layers of wood veneers bonded together with adhesive. However, the key differentiator is the treatment applied to these layers, making treated plywood more suitable for outdoor use where it might come into contact with moisture or soil.
4. Resistance to Decay
One of the primary advantages of treated plywood is its resistance to decay and rot. The chemical treatment enhances the plywood’s ability to withstand the elements, making it a preferred choice for applications requiring protection against moisture, such as decks, fences, and exterior structures.
5. Cost Considerations
While treated plywood offers enhanced durability and resistance to decay, it is generally more affordable than marine plywood. This cost-effectiveness makes treated plywood a practical choice for projects where budget constraints are a concern.
