Selecting the right plywood for a given application depends on the strength, performance, resistance to moisture, heat and pests, and durability required. Each type of plywood comes with its own set of advantages that make it suitable for certain types of projects or decor. Understanding the differences between marine plywood vs commercial plywood in terms of performance, durability, and uses may help one make the right choice for long-lasting furniture.

Quick Summary

There are some distinct differences between marine plywood and commercial plywood when it comes to resistance to moisture, durability, and intended use. Marine plywood uses the best quality wood veneers that are glued together with BWP (Boiling Waterproof) adhesives, so they are extremely water-resistant and do not support the growth of insects or fungus. Commercial plywood is glued together with MR (Moisture Resistant) grade adhesives that make it suitable primarily for indoor furniture and low moisture areas. Marine plywood is great for kitchens, bathrooms, outdoor furniture, and marine applications. Commercial plywood can be found in indoor furniture, room dividers, and wardrobes.

Marine Plywood vs Commercial Plywood

What is Marine Plywood?

Marine plywood is designed to resist moisture and exposure to water and is best suited for those projects where there is a presence of high humidity, a need for frequent contact, or the furniture is present outdoors and can be exposed to seasonal rains. Marine plywood is constructed from the best quality wood veneers and is bonded with waterproof adhesives using BWP (Boiling Waterproof) grade adhesives. Dense solid wood is used in manufacturing marine plywood to add to its strength and provide resistance against delamination, warping, and rotting.

Characteristics of Marine Plywood

Water Resistance

Marine plywood is developed to withstand heavy exposure to water without degrading.

Durability

Marine plywood is very tough and sturdy compared to commercial plywood. This is obtained from the use of high-quality wood veneers.

Resistance to Borer and Fungus

Since it uses waterproof bonding, marine plywood is resistant to pest infestation and fungal growth.

Smooth Finish

The surface of marine plywood is relatively smoother, making it suitable for high-quality finishes.

Applications of Marine Plywood

As it is water-resistant, this type of plywood can be used where there is extended contact with water, such as:

Construction of Boats and Ships

It is suitable for parts of boats because it resists water.

Outdoor Furniture

Marine plywood is apt for patio furniture, benches, and tables.

Bathroom and Kitchen Cabinets

Can be installed in wet exposure locations.

Outdoor Decking

Since it is tough and resistant to warping, it is best for exterior flooring applications.

What is Commercial Plywood?

Commercial plywood is one of the widely used types of plywood. It is less resistant to water compared to marine plywood. Commercial plywood is bonded using MR-grade adhesive and slightly lower quality veneers.

Key Features of Commercial Plywood

Affordability

Commercial plywood is relatively less expensive compared to marine plywood.

Average Resistance to Water

It can withstand slight exposure to moisture but cannot be used where extended contact with water is expected.

Strength

It has reasonable strength for use in lightweight applications.

Application of Commercial Plywood

Commercial ply is used indoors where moisture content is relatively low. Since it is made to sustain less strength than marine plywood, one can use it in select furniture and interior décor such as:

Furniture

Suitable for indoor furniture that doesn't require load-bearing, for example, shelves, cupboards, and tables.

Partitioning

Most commonly used for partitioning the walls of a given office where water and termite resistance is not required.

Cabinets and Wardrobes

Suitable for kitchen and bedroom cabinets not exposed to high moisture content, as an inexpensive option compared to marine plywood.

Royale Touche offers high-quality marine plywood that suits various needs in residential and industrial areas and is designed to be robust, strong, and high-performing. Royale Touche offers choices that not only meet industry standards but also provide great value for both in-house and outdoor projects.

Choosing between marine ply vs commercial ply depends on the requirements of a project as well as the environment in which the ply is to be used. As marine plywood allows for more flexibility with durability and water resistance, it is ideal for outdoor, indoor, and moisture-prone areas. Commercial ply is ideal for indoor applications at a lesser cost. Brands like Royale Touche Plywood make a good choice for both types, offering premium-quality plywood for diversified needs. Reflecting on the nature of the project, the amount of exposure to moisture, and the budget, one should choose the plywood type.

How to Choose the Right Plywood for Your Needs

The type of plywood you choose to use in your project depends on various practical factors, including the type of project you're doing and the kind of environment or conditions the project will be subjected to. Understanding these practical factors and how they relate to your project can help to give you furniture or structures that will last a long time.

Moisture Exposure: If the furniture or area where the furniture will be installed will have exposure to water, humidity, or frequent cleaning, then a marine-grade plywood would be the best choice, as it is waterproof and has a waterproofed bond.

Application Type: If you're building outdoor furniture, kitchens, bathrooms, or in any marine environment, you should use marine-grade plywood. If you're building indoor furniture, such as wardrobes and partition walls, or shelves, then commercial-grade plywood will most likely suffice.

Price: Generally, commercial-grade plywood is cheaper than marine-grade plywood so if your project requires little or no exposure to moisture, then you should use commercial-grade plywood. Conversely, if your project requires a much higher degree of durability, strength, and moisture resistance, then you will probably need to use marine-grade plywood.

Durability Requirements: If your project requires a high degree of durability and strength over an extended period, then you'll want to use marine-grade plywood. If your project will be subjected to or will usually be involved in light-duty uses, then you would most likely be okay using commercial-grade plywood.

Frequently Asked Questions

Does the plywood produced commercially have waterproof qualities?

The plywood manufactured commercially does contain an adhesive that can withstand humidity, but it is not designed or rated to withstand long-term contact with water, so it will not be as resilient to that exposure compared to marine-grade products.

Is Marine Plywood superior to other types of plywood?

Marine plywood is made with high-quality veneers and waterproof adhesives. These qualities allow marine plywood to resist water damage, as well as insect infestation and fungal growth.

Is marine plywood suitable for installation indoors?

Yes; marine plywood can be installed indoors. Since kitchens, bathrooms, and laundry rooms have higher humidity levels, marine-grade plywood is an excellent selection in those installation environments.

When should I use thicker versus thinner sheets of plywood?

The choice of weight will be based on the intended end use of the plywood sheet. If the application is for a cabinet, shelf, or piece of furniture that requires load-bearing capacity, you should use a thicker sheet of plywood; however, if the application is more decorative, such as for use as a decorative partition or panel, then thinner sheets would suffice.

Can marine plywood be applied indoors?

Marine plywood can be used indoors in particular areas where humidity is high and where there is a possibility of moisture. This includes areas like the kitchen or bathroom.

What is the primary difference between marine plywood and commercial plywood?

The main difference between marine plywood vs commercial plywood is that marine ply has more resistance to water, whereas commercial plywood is less resistant to water.

Which is more inexpensive: commercial ply or marine ply?

Commercial ply is cheaper than marine ply given the superior quality of materials and waterproof adhesives used in marine ply.
