What Is Exterior Plywood Called And What Makes It Different?

What is exterior plywood called? This blog provides information about exterior plywood, including its different names, manufacturing process, advantages, and tips for using and caring for it properly.

It emphasizes the importance of using the right type of plywood for outdoor projects and provides practical advice for ensuring the longevity and performance of exterior plywood.

What Is Exterior Plywood Called? The Different Names For Exterior Plywood:

Exterior plywood is known by different names, which reflect its unique characteristics and intended use. The most common names for exterior plywood are marine plywood, weather-resistant plywood, and waterproof plywood.

What is exterior plywood called? – Marine plywood

Marine plywood is often used for boat building, while weather-resistant plywood and waterproof plywood are designed for outdoor use. These names reflect the plywood’s ability to resist water and moisture, making it ideal for use in harsh outdoor environments.

Marine plywood is specially designed for use in marine environments, where it will be exposed to saltwater, humidity, and extreme temperatures.

Marine plywood is made with high-quality hardwood veneers and is highly resistant to rot and decay. This makes it ideal for use in boat building and other marine applications.

What is exterior plywood called? – Weather-resistant plywood

Weather-resistant plywood is designed to withstand exposure to moisture, humidity, and extreme temperatures. It is made with waterproof glue and high-quality veneers that are treated with preservatives to enhance their resistance to decay and rot.

This makes it ideal for use in outdoor construction projects, such as decking, roofing, and cladding.

What is exterior plywood called? – Waterproof plywood

Waterproof plywood is similar to weather-resistant plywood, but it is designed to be completely waterproof. It is made with a combination of waterproof glue and treated veneers that can withstand exposure to water and moisture.

This makes it ideal for use in applications where the plywood will be constantly exposed to water, such as in bathrooms or wet areas.

How Is Exterior Plywood Made? What Makes It Different From Other Types Of Plywood?

Exterior plywood is made using a different manufacturing process than interior plywood. The main difference is that exterior plywood is made with waterproof glue and high-quality veneers that are selected for their resistance to rot and decay.

The veneers are often made from tropical hardwoods or softwoods, which are naturally resistant to moisture and decay.

The manufacturing process involves gluing together several layers of veneers, with the grain direction alternating between each layer. This gives the plywood strength and stability. The plywood is then treated with preservatives to enhance its resistance to decay and rot.

The use of waterproof glue and treated veneers makes exterior plywood more durable and resistant to moisture than interior plywood. This makes it ideal for use in outdoor construction projects, where the plywood will be exposed to the elements.

What Are The Advantages Of Using Exterior Plywood?

Using exterior plywood in outdoor construction projects offers several advantages over using interior plywood. Exterior plywood, such as ROCPLEX’s BS1088 Marine Plywood, offers several advantages over interior plywood, including:

High-Quality Standards:

ROCPLEX Marine Plywood is manufactured to meet BS1088 standards, ensuring excellent strength properties and waterproofing. This plywood is highly resistant to moisture and will not warp or crack when exposed to the elements.

ROCPLEX Marine Plywood can be used for a multitude of applications, including the manufacture of boats, canoes, wall panels, interior cladding, and furniture. It is also suitable for woodworking and artists’ tools and can be used for laser and waterjet cutting.


ROCPLEX Marine Plywood is made from tightly-peeled solid and joint-free Okoume veneers, which make it strong and durable. Its strong nail holding and excellent bending strength make it an ideal choice for outdoor construction projects.

Environmental Friendliness:

ROCPLEX Marine Plywood is taint and odor-free, with low formaldehyde emission and a super E0 environmental rating. It is also suitable for use in environmentally sensitive areas.

Aesthetically Pleasing:

The joint-free face of ROCPLEX Marine Plywood creates a beautiful panel with a light, solid, and homogeneous appearance. It can be waxed, stained, lacquered, or left as is to showcase the natural beauty of the wood and its unique grain pattern.

How To Use And Care For Exterior Plywood?

Using and caring for exterior plywood properly is important to ensure its longevity and performance. Here are some tips to keep in mind when using exterior plywood:

  •  Use the right grade of plywood for the job.

Exterior plywood is available in different grades, with higher grades offering greater strength and durability. Choose the appropriate grade for your project to ensure it will last.

  •  Protect the plywood from moisture.

Even though exterior plywood is designed to be moisture-resistant, it is still important to keep it as dry as possible. Avoid leaving it in standing water or exposing it to heavy rain.

  •  Seal the plywood.

Applying a sealant to the plywood can help protect it from moisture and UV damage. There are several types of sealants available, including paint, varnish, and wood stain. Choose the appropriate sealant for your project and apply it according to the manufacturer’s instructions.

  •  Avoid placing heavy objects on the plywood.

Exterior plywood is strong and durable, but it can still be damaged by heavy objects. Avoid placing heavy furniture or equipment directly on the plywood, and use supports or padding to distribute the weight.

  • Clean the plywood regularly.

Dirt and debris can accumulate on the surface of the plywood, which can reduce its lifespan. Clean the plywood regularly with a soft brush or cloth and mild soap and water.

Final Words:

Exterior plywood is a durable and versatile material that is ideal for use in outdoor construction projects. It is resistant to moisture, decay, and rot, which makes it ideal for use in harsh outdoor environments.

By understanding the different names for exterior plywood, the manufacturing process, and how to use and care for it properly, you can ensure that your outdoor construction project will be long-lasting and high-quality.

Always choose the appropriate grade of plywood for your project, and protect it from moisture and heavy objects to ensure its longevity.
