Blockboard vs Plywood – Which one do you choose?

Blockboard vs plywood, Most people get confused with these terms because of the similarity in looks, and both products are popularly used in interior works, home decor, and furniture works. In reality, both these materials are different types of engineered wood and possess entirely different properties, and are used for specific interior applications.

Blockboard, with its core of softwood strips sandwiched between veneers, is known for its strength and durability. In contrast, plywood features multiple layers of thin veneer glued together, providing flexibility and stability. As you weigh plywood vs block board, consider how each material meets your needs for load-bearing, cost, and aesthetics. Blockboard plywood is often preferred for heavy-duty applications, while plywood and blockboard both offer versatility for different uses. This blog explains and clarifies the differences and properties of ply board/block-board and can make the right choice.

What is plywood?

Plywood is an engineered wood panel manufactured by joining sliced wood veneers 2-4 mm thick in a cross-layered pattern and pressed under high temperature to form sheets.Unlike blockboard, plywood is flexible and resistant to warping. This makes it ideal for a wide range of applications, from furniture to construction. When comparing blockboard vs plywood, plywood’s adaptability and ease of use stand out.

What is Plyboard or blockboard?

Plyboard or blockboard is an engineered wood panel made of a core comprising of softwood wooden strips or blocks placed edge to edges sandwiched between two wood veneer layers. This construction gives it strength and durability, making it ideal for heavy-duty applications like furniture and doors. These veneer layers are glued and pressed under high pressure and temperature to form a plyboard/blockboard. Compared to plywood, blockboard is thicker and provides better load-bearing capacity. When considering blockboard vs plywood, blockboard excels in situations requiring robust support and rigidity.

Manufacturing process – Blockboard vs Plywood

Blockboard/PlyboardPlywood
Small wooden strips are placed
edge to edge sandwiched between sliced wooden veneers.
Plywood is made in an odd number of veneer layers starting from 3 layers
more depending on the thickness of the plywood.
Block boards are made in either
3 layers or 5 layers. It is like a
wooden frame filled with small
wooden strips and covered by
wooden veneers on the faces.
The veneers are arranged in a cross layered pattern.

Blockboard vs plywood involves different core materials and manufacturing methods. Blockboard has a core of softwood strips with outer veneers, while plywood features alternating layers of veneer. Each method affects the material’s strength, flexibility, and final use.

Ease of handling – Plywood vs Blockboard

Blockboard/plyboardPlywood
Blockboard mostly uses softwood core and hence blockboard is lighter than plywood.Plywood grades use dense hardwood and the layers are pressed to form plywood.
Due to their lightweight nature, they are easy to transport and handle.plywood is solid and heavier than Blockboard.

Blockboard uses softwood for its core, making it lighter compared to plywood, which uses dense hardwood veneers. Consequently, blockboard is easier to handle and move, while plywood’s weight can make it more challenging to work with.

Strength and durability

Plyboard/BlockboardPlywood
Mostly uses softwood in the core. Softwoods are soft and have low strength and hence blockboards have moderate strength.Mostly uses hardwood veneers arranged in a uniform cross-layered pattern. Plywood is much stronger than blockboard.
Plyboard is strong compared to particleboard and MDF but is less durable as compared to plywood.Low-density plywood can even take moderate loads. They are strong and durable when compared with blockboards/plyboards.
Blockboard looks plain from the outside, but minor gaps are inside the core.Plywood layers are uniform in both directions and no gaps will be there.

Blockboard provides robust strength due to its core of softwood strips, making it suitable for heavy-duty applications. However, it can be affected by moisture. Plywood, with its layered veneer construction, offers consistent strength and high durability, making it resistant to environmental changes and suitable for diverse uses.

Water and moisture resistant properties

Plyboard/BlockboardPlywood
Blockboards retains moisture and more prone to water and moisture damages.Plywood grades like BWR (Exterior Grade)and Marine ply are less suspectable to water and moisture.
They can be made waterproof by using BWP Grade (Boiling Water Proof) resin for bonding the strips.Plywood grades like BWR (303 grade) and Marine ply (710 grade) are superior to block boards in terms of moisture and water-resistant properties.

Physical properties

Plyboard/BlockboardPlywood
Bending and sagging
Plyboard is more stiffer than plywood
and do not bend when used as
long pieces. Block board is preferred over plywood when used as lengthy
panels and furniture.
Long pieces of plywood may sags from the centre. Plywood is
less stiffer than blockboard.
Warping and Cracking
It has good dimensional stability and so is highly resistant to warping and crackingIt is resistant to warping and cracking.
Splitting on edges
Plyboard does not split on edges while cuttingPlywood split on edges while cutting.
Block board is comparatively easy to cut.Plywood splinter on edges and is very difficult to cut.

Blockboard vs plywood differs in density, thickness, and other physical properties. Blockboard, with its softwood core, is typically thicker and less flexible but provides a smooth surface. Plywood, made from layered veneers, is denser, more flexible, and offers better dimensional stability.

Screw holding capacity

Plyboard/BlockboardPlywood
Blockboards have very good screw holding capacity, than particle board and MDF. They can hold nails very well and thus are used for making custom made furniture. Also they are used as core in flush doors, where screw holding capacity is essential.Got excellent screw holding capacity due to the cross layered arrangement of veneers. The hinges do not come out easily.
Some times the screws tend to go between
the gaps of the wood pieces. Skilled carpenters
can identify and manage the problem

In the blockboard vs plywood comparison, plywood typically offers better screw holding capacity. The layered veneer structure of plywood provides more grip, making it suitable for applications where secure fastening is essential. Blockboard, with its softer core, may have screws loosen over time and is less reliable for high-stress fastening.

Flexibility in Applications: Blockboard vs Plywood

AspectBlockboardPlywood
Application VersatilityLess versatile; best suited for applications requiring solid and stable support, such as heavy-duty furniture and doors.Highly versatile; used in a wide range of applications including cabinetry, wall panels, and structural components.
CustomizabilityLimited in terms of bending or shaping; typically used in flat applications.More flexible; can be easily cut, bent, and shaped for various designs and structures.
Use CasesIdeal for applications requiring strength and stability but less flexibility.Ideal for both structural and decorative purposes due to its adaptability and ease of modification.

Plywood is more flexible in applications due to its ability to be shaped and customized easily. In contrast, blockboard is less adaptable, making it suitable primarily for stable, heavy-duty applications.

Applications: Blockboard vs Plywood

AspectBlockboardPlywood
Typical UsesCommonly used for heavy-duty furniture, long bookshelves, benches, doors, partitions, and panels where solid support is needed.Widely used in cabinetry, wall paneling, flooring, structural components, and various DIY projects due to its versatility.
Suitability for Interior DesignSuitable for high-end furniture and cabinetry where a smooth finish and robustness are required.Ideal for a broad range of interior design projects, including furniture, shelving, and decorative panels.
Structural UsesBest for applications requiring solid core strength but less flexibility in design.Common in structural applications like roof sheathing, subflooring, and wall sheathing due to its strength and flexibility.

Blockboard is ideal for applications needing solid support, such as heavy-duty furniture and doors. Plywood, being versatile and flexible, is used in a wide range of applications from cabinetry and wall paneling to structural components.
