Journey with Comfort: Understanding and Choosing Plywood for Your RV

RV Plywood, a specialized material used extensively in recreational vehicles, stands as the backbone for many of an RV’s structural and design elements. This wood isn’t just chosen for its visual appeal, but it carries with it implications for the overall safety, durability, and comfort of the vehicle. Given the unique challenges faced by RVs, from changing weather conditions to the demands of the road, selecting the right plywood is a decision that resonates with every bump and turn. As such, understanding the various types and their properties becomes not just a matter of craftsmanship, but also of practicality and ensuring memorable, hassle-free adventures on the open road.

Types of Plywood

Softwood vs. Hardwood Plywood

Softwood plywood is made from coniferous trees like pine or cedar, while hardwood plywood comes from deciduous trees like oak or maple. Softwood plywood is lighter and less expensive, making it suitable for structural applications. Hardwood plywood is more durable and aesthetically pleasing, often used in fine woodworking.

Marine Plywood: Why is it a Popular Choice for RVs?

Marine plywood is renowned for its water-resistant properties, thanks to its superior adhesive and high-quality veneers. This makes it an ideal choice for RV construction, as it can withstand exposure to moisture and humidity, crucial for mobile homes that may encounter various weather conditions during travel.

Other Types: Baltic Birch, Lauan, and OSB

  • Baltic Birch Plywood: Known for its exceptional strength and durability, Baltic Birch plywood is made from birch veneers. Its fine, multi-layered structure and smooth surface make it a top choice for furniture and cabinetry.
  • Lauan Plywood: Lauan, or Philippine Mahogany plywood, is a cost-effective option. It’s commonly used for interior applications, such as wall paneling and underlayment.
  • OSB (Oriented Strand Board): OSB is an engineered wood product made from pressed wood strands. It’s budget-friendly and suitable for structural sheathing and subflooring in construction.

Grades of Plywood

What is Plywood Grading

Plywood undergoes a comprehensive grading system that evaluates its quality, appearance, and intended applications. This grading system is a valuable tool for purchasers, assisting them in selecting the most suitable plywood for their unique projects. Here are key grading categories you’ll encounter:

  • A Grade: Representing the pinnacle of quality, A grade plywood boasts minimal imperfections. Its surface is impeccably smooth and sanded, making it the preferred choice for fine woodworking and crafting exquisite furniture pieces.
  • B Grade: Slightly less pristine than A grade, B grade plywood may display some visible defects. Nevertheless, it remains appropriate for applications where aesthetics hold importance, striking a balance between quality and cost.
  • C Grade: C grade plywood exhibits more conspicuous imperfections but retains structural integrity. It frequently finds application in construction projects where appearance takes a backseat to functionality and durability.
  • D Grade: Occupying the lower end of the grading spectrum, D grade plywood is primarily designated for structural purposes. Its focus is on strength rather than appearance, and it may feature knots, voids, and other surface blemishes.

Selecting the Ideal Grades for RV Applications

In the context of RV construction, it is generally advisable to opt for higher-grade plywood, such as A or B, in areas where aesthetics and smooth surfaces are paramount, like cabinetry and furniture components. Conversely, for structural elements where visual appeal is less critical, C or D grade plywood can fulfill the requirements effectively.

Evaluating Cost and Benefit: Premium Grades vs. Lower Grades

  • The choice between premium and lower-grade plywood hinges on your budget and the specific demands of your project. Premium grades, exemplified by A and B grades, offer superior visual appeal and may entail less finishing work, albeit at a higher price point. In contrast, lower grades like C and D are budget-friendly but may necessitate additional effort during finishing or may be best suited for concealed applications.
  • In an RV construction endeavor, a judicious approach often involves a combination of plywood grades tailored to the intended use of each component. Leveraging premium grades for visible surfaces like cabinetry, complemented by lower grades for structural elements, strikes a harmonious balance between affordability and aesthetics.
  • Ultimately, a firm grasp of the plywood grading system empowers you to make informed choices, ensuring that your RV project aligns seamlessly with both your budget constraints and aesthetic aspirations.

Durability and Maintenance

Durability and Maintenance: Keeping Plywood in Prime Condition

RV Plywood is a versatile and widely used material, but its longevity and performance depend on proper maintenance. Here are key considerations for ensuring the durability of plywood and effective maintenance practices.

Protecting Plywood from Moisture and Other Damage

Moisture is the primary enemy of plywood. To safeguard it, consider these precautions:

  • Sealing Edges: Seal exposed edges with paint, sealant, or edge banding to prevent water penetration.
  • Proper Ventilation: Ensure good ventilation in areas where plywood is used to minimize humidity buildup.
  • Elevate Off the Ground: When used in outdoor applications, keep plywood elevated off the ground to prevent direct contact with moisture.

Regular Check-ups: Looking for Warping, Delamination, and Other Issues

  • Routine inspections are essential for identifying potential problems:
  • Warping: Check for warping or bowing, which can occur due to uneven moisture exposure. Replace affected sheets promptly.
  • Delamination: Inspect for signs of delamination, where layers separate. This often results from exposure to extreme temperature fluctuations or excessive moisture.
  • Cracks and Damage: Look for cracks, chips, or damage to the surface. Sand and repair these areas as needed to prevent further deterioration.

Best Practices for Cleaning and Upkeep

Proper cleaning and upkeep can extend the life of plywood:

  • Dust Removal: Regularly remove dust and debris from surfaces to prevent scratching and maintain a clean appearance.
  • Gentle Cleaning: Use a mild detergent and water solution for cleaning. Avoid harsh chemicals that can damage the finish.
  • Avoid Excessive Weight: Plywood can sag or warp under heavy loads. Distribute weight evenly to prevent stress on the material.
  • Recoating: Over time, plywood finishes may wear off. Recoat as necessary to protect against moisture and maintain appearance.


In the journey towards RV comfort, understanding and selecting the right RV Plywood is pivotal. From comprehending grading systems to making choices that balance cost and quality, plywood plays a crucial role in the durability and aesthetics of your mobile haven. By taking the time to make informed decisions and prioritize maintenance, you can embark on a road trip with the confidence that your RV’s plywood components will contribute to a comfortable and enjoyable adventure.
