What is RTD in Plywood?

RTD stands for “Rated for Temporary Decking” in plywood, and it’s a designation used in the construction industry. It typically refers to plywood that is specifically designed and manufactured to be used as a temporary decking material during the building process, especially for flooring and roofing in construction projects. This plywood is intended to be used temporarily until more durable materials are installed.

Key Characteristics of RTD Plywood

• Temporary Use: RTD plywood is not designed for long-term exposure to the elements, but rather as a temporary surface to support workers and materials during construction.
• Strength: RTD plywood is strong enough to bear weight during the construction phase but is not meant to serve as a permanent flooring or decking material.
• Moisture Resistance: It is typically treated to handle some moisture, but prolonged exposure to water can degrade the material. Once the project is completed, the RTD plywood should be replaced with more permanent, moisture-resistant materials like OSB or treated plywood.

Common Applications of RTD Plywood

• Temporary Flooring: Used as a surface for workers and equipment during the building process.
• Roof Decking: Provides a stable, temporary surface for roof framing or during roofing installation.
• Scaffolding Support: Can be used in scaffolding systems to support workers and materials during construction or renovation.

Advantages of RTD Plywood

1. Cost-Effective: RTD plywood is generally less expensive than high-quality plywood meant for permanent structures.
2. Durability for Temporary Use: While it’s not made for long-term use, RTD plywood can withstand the stress and wear of a construction site.
3. Lightweight: RTD plywood tends to be lighter than other forms of structural plywood, which can make it easier to handle and install during construction.

Disadvantages of RTD Plywood

1. Not Durable Long-Term: RTD plywood is not suitable for long-term applications, as it may degrade quickly when exposed to moisture or heavy wear.
2. Limited Moisture Resistance: While it can withstand temporary exposure to moisture, it is not as moisture-resistant as treated or marine-grade plywood.
3. Aesthetics: RTD plywood is not intended for visible use, meaning it often has imperfections or visible defects that make it unsuitable for finished surfaces.

Conclusion

RTD plywood is an essential material for temporary decking and other construction applications. It is designed to provide a stable, affordable surface during the building phase of a project but should be replaced with more durable materials once construction is completed. Its cost-effectiveness and lightweight nature make it an ideal choice for temporary use, but it should not be used for permanent flooring or outdoor structures exposed to moisture.
