Types Of Plywood Board in India & Their Uses
On this page 9 sections
Plywood boards are grouped by the wood they are made from (softwood, hardwood or tropical), by how well they resist water (MR, BWR, BWP, marine, exterior and interior) and by their purpose (structural, film-faced, flexible, fire-retardant, decorative and more). The right type depends on where the board will be used, how much moisture it will face and the load it has to carry.
In India, demand for quality plywood is high because of rapid urbanisation and infrastructure development, and understanding the types available helps buyers and builders make informed decisions. This guide explains the main types of plywood boards, their uses, and how to select the best one for your needs.
What Are Plywood Boards?
Plywood boards are engineered wood products made by gluing together thin layers, or veneers, of wood. These layers are arranged with their grains running perpendicular to each other, enhancing the strength and stability of the board.
The quality and type of plywood depend on the species of wood used, the adhesive used for bonding, and the number of layers. Different types, such as commercial plywood, marine plywood, and BWP plywood, are each designed for specific purposes based on factors like water resistance, durability, and structural requirements.
Types of Plywood by Wood Species
Softwood Plywood
Softwood plywood is made from coniferous trees such as pine, fir, or spruce. It’s commonly used in construction for roofing, walls, wall sheathing, and subflooring. Softwood plywood is lightweight, durable, easy to work with, and widely available.
Hardwood Plywood
Hardwood plywood is made from denser deciduous hardwood species like oak, maple, or birch. It is generally stronger and more resistant to wear and tear than softwood plywood, and it is known for its aesthetic appeal. It’s often used in furniture making, cabinetry, flooring, interior paneling and high-end interior projects that need a polished finish.
Tropical Plywood
Tropical plywood is manufactured from mixed tropical hardwoods. It is highly durable and resistant to wear, and it is commonly used in construction, shipping, and industrial applications because of its strength and ability to withstand harsh conditions.
Types of Plywood by Water Resistance
Moisture Resistant (MR) or Commercial Plywood
Commercial plywood, often referred to as MR (moisture resistant) grade plywood, is made from softwood veneers bonded with phenolic or urea-formaldehyde adhesives. It is treated to resist moisture but is not waterproof, so it suits indoor use in areas with moderate humidity, such as living rooms and bedrooms. MR plywood is a cost-effective, general-purpose board for cabinets, tables, chairs, interior wall panels, and partitions.
BWR (Boiling Water Resistant) Plywood
BWR plywood is made from hardwood veneers bonded with phenolic resins, which makes it durable and more moisture-resistant than MR plywood. See BWR vs BWP plywood for how it compares with the next grade up.
BWP (Boiling Water Proof) Plywood
BWP plywood is similar to marine plywood but is specifically designed to withstand boiling water. This makes it ideal for kitchens, bathrooms, and other areas where water exposure is frequent. BWP plywood is strong, durable, and resistant to warping.
Marine Plywood
Marine plywood is designed for use in environments where moisture is a concern. It’s made from durable hardwood veneers bonded with waterproof glue, so it can withstand prolonged exposure to water without warping or rotting, and it resists termites. Marine plywood is commonly used in boat building, docks, garden furniture, and other outdoor applications in marine and coastal areas.
Exterior Plywood
Exterior plywood is designed for outdoor use. It’s made with waterproof glue and weather-resistant veneers, and treated with chemicals so it can withstand exposure to the elements. Exterior plywood is used for siding, roofing, outdoor furniture, fences, sheds, and other outdoor structures, and it can be painted or stained for extra protection.
Interior Plywood
Interior plywood is designed for indoor use. It’s made with veneers that are less resistant to moisture and weathering, making it suitable for furniture, interior walls, cabinetry, and other interior applications. Because it is not treated for moisture resistance, it should not be used in areas exposed to high humidity. Interior plywood is available in various grades and finishes.
Types of Plywood by Purpose and Finish
Structural Plywood
Structural plywood is engineered for load-bearing applications. It’s used in construction for framing, roofing, subflooring, and other structural elements in houses, bridges, and commercial buildings. Structural plywood is made from high-quality veneers and is certified for its strength and stability.
Film-Faced Plywood
Film-faced plywood is coated with a film that improves its durability and water resistance. Because it withstands harsh site conditions, it is commonly used for concrete formwork and moulds and for construction scaffolding. Read more about shuttering plywood.
Flexible Plywood
Flexible plywood, also known as bendy plywood, is designed to bend easily without cracking. It’s used for creating curved surfaces in furniture and interior design. Flexible plywood is not as strong as other types and should not be used for load-bearing applications, so it’s best used for decorative or design-focused purposes.
Fire Retardant Plywood
Fire retardant plywood is treated with chemicals that slow the spread of fire. It’s used in buildings where fire safety is a priority, such as schools, hospitals, public structures, and commercial buildings, and in projects that must comply with fire safety regulations. Fire retardant plywood is available in various grades and finishes.
Pressure-Treated Plywood
Pressure-treated plywood is infused with preservatives to resist rot, insects, and decay. It is designed to withstand harsh environmental conditions, including ground contact, and is commonly used in outdoor projects like decks, fences, and garden beds.
Decorative Plywood
Decorative plywood is designed for aesthetic purposes. It’s often used for interior paneling, furniture, and cabinetry. It comes in various finishes, including natural wood veneers in different species, printed patterns, and laminated decorative surfaces; see our veneer customization options.
Aircraft Plywood
Aircraft plywood is made from thin, high-grade veneers of woods such as mahogany or birch, and it is extremely strong, lightweight, and flexible. It’s used in the construction of aircraft, as well as in high-end furniture and musical instruments that need precision and strength. Aircraft plywood is more expensive than other types due to its superior quality.
Related Boards: Blockboard and Flush Doors
Blockboard and flush doors are often listed alongside plywood types in India, although they are different products:
- Blockboard: A core of softwood blocks sandwiched between outer layers that are often high-quality veneer. It offers good strength and is lighter than plywood, so it is used for interior partition panels in offices and homes, and for doors and cabinets. See blockboard vs plywood for a full comparison.
- Flush doors: Doors made with a solid core encased in a veneer or plywood face. They are known for their smooth finish and durability and are commonly used as interior doors in homes and commercial buildings; specially treated flush doors can be used as fire-resistant doors.
How To Choose The Right Types Of Plywood Board?
Choosing the right types of plywood board involves considering several factors. First, identify the application, whether it’s for construction, furniture, or outdoor use. Next, evaluate the environmental conditions, such as moisture levels and load requirements.
1. Consider the Application
The first step in choosing the right plywood board is to consider the application. Are you building furniture, constructing a roof, or designing a boat? Different types of plywood boards are suited for different applications. For example, commercial plywood suits indoor furniture, while marine plywood is best for outdoor and water-exposed areas.
2. Evaluate the Environment
Consider the environment where the plywood will be used. MR plywood suits moderate moisture indoors, and BWR offers more resistance. If the board will be exposed to frequent water, choose a waterproof plywood such as BWP or marine plywood; for outdoor projects, marine or exterior plywood.
3. Match the Strength to the Load
For structural uses, such as formwork or heavy furniture, opt for high-grade plywood with strong adhesive bonding, or structural plywood for load-bearing work.
4. Check The Grade
Plywood is available in different grades, which indicate the quality of the face veneers. Higher-grade plywood has fewer knots and defects, making it ideal for visible applications like furniture. Lower-grade plywood is suitable for structural applications where appearance is not a concern.
| Grade | Surface | Typical uses |
|---|---|---|
| A | Smooth, sanded surface with minimal defects | Furniture, cabinetry and fine woodworking that will be painted or stained |
| B | Minor defects such as small knots or patches; slightly rougher than A | Visible areas where a perfect finish is not necessary |
| C | Larger knots and defects; may need sanding or patching | Framing, subflooring and other structural work |
| D | Numerous defects and imperfections | Subflooring, roofing and temporary structures where appearance does not matter |
5. Look At The Thickness
Plywood comes in various thicknesses, typically from 1/8 inch to 1 inch. The thickness affects its strength and durability: thicker plywood is stronger and can support heavier loads, making it suitable for flooring and structural applications, while thinner plywood is lighter and easier to work with, making it ideal for furniture and paneling. Our guide to plywood thickness covers each size.
6. Consider The Finish
Veneered or decorative plywood gives a polished look for visible surfaces, while film-faced plywood is more utilitarian.
7. Consider The Budget
The cost of plywood depends on the type, grade, and thickness. Marine and BWR plywood cost more because of their enhanced properties, while commercial plywood and blockboard are cost-effective for less demanding applications. Higher-quality plywood is often worth the investment for its durability and performance, so balance your budget with the requirements of your project.
