All You Need To Know About Blockboards
Many of you may be confused with the term ‘blockboard,’ which often sounds similar to the blackboard.
Blockboards are used in the plywood industry or furniture-making processes.
Blockboards aren’t a new invention. They were a big part of Egyptian furniture-making techniques back in the day.
According to the kind of wood used, there are two types of blockboards. First, Softwood, and second, Hardwood.
According to grades, again, it is classified into two majors. First, based on MR Grade, and second, BWP or BWR Grade.
All blockboard categories are different from each other and used respectively.
In this blog, you’ll learn about the uses, precautions, and manufacturing designs of blockboards.
What is Blockboard and the Manufacturing Process of Blockboard
Blockboard (also known as lumber core) is an artificial board, i.e. an artificial board that looks similar to plywood, but the center layer is made from softwood strips. The design of the blockboard is achieved when the strips are put in every corner and sandwiched between veneers of softwood, hardwood, or MDF, pulp under extreme pressure, and heat with glue.
Now that you understand what blockboards are, let’s dive into their manufacturing process.
The followings are The Steps of Blockboard Processing:
- Acquiring raw materials, i.e. timber.
- Slicing Wood/ Rotary Cutting. In this process, the logs of lumber woods are sliced at 25mm or as per industry standards.
- The next process is gluing, in which slices of glue or adhesive are used to attach the sliced wood.
- The blocks are then left for drying to reduce the moisture. After successfully drying, they are ready to make a sandwich.
- The next step involved is attaching the blocks. They are attached after deciding which block boards are required, i.e. softwood or hardwood.
- Finishing is given with lamination, brand printing, and coating for high durability at the final stage.
Significant Uses of Blockboard
Nowadays, processed blockboards are used in everything that deals with furniture, such as dining tables, beds, wardrobes, flush doors, benches, etc.
Blockboards can be used for furnishing homes and offices. Here are some uses of it
- For making tables, benches, and wall furniture
- Used for blockboard doors and solid core flush doors
- For creating single and double beds and settees
- For making beautiful wall panels and partitions
- For woodwork in railway carriages
- For interior and exterior decoration
- It is also used in making study shelves, window shelves, etc
In addition to this, blockboards are used for both decorative and commercial uses. When it comes to something more decorative, the veneer is used mostly on either side to create high-quality furniture, paneling, partition design, and interior decoration.
In commercial type, the composition used is veneers of timber on either side. It is used for making tabletops seats in buses and railway coaches.
Blockboard Grade and Types With Their Symbol
To identify the blockboard, the grades and types of boards are represented by the symbols below:
|Grade and Type||Symbol|
|BWP Grade, Decorative Kind||BWP-DEC BWP Grade|
|Commercial Kind||BWP-COM MR Grade|
|Exclusive Decorative Kind||MR-DEC MR Grade|
Available Sizes and Thickness of Blockboard
|Size (in sq.feet)||Size in mm (rounded values)|
|8′ x 4′||2440 x 1220|
|8′ x 3′||2440 x 915|
|7′ x 4′||2135 x 1220|
|7′ x 3′||2135 x 915|
|6′ x 4′||1830 x 1220|
|6′ x 3′||1830 x 915|
Based on IS Code 1659, the blockboard thicknesses are as follows:
|Blockboard Size (in sq. feet)|
Precautions To Be Taken While Assembling Blockboard
High-quality blockboards can be produced when the proper measures are applied with minimum hindrance.
Precautions for blockboard production:
- Pieces of reasonable thickness are carefully sandwiched between the facade/veneers
- No hole should shape between the strips while putting softwood.
- The strips should be stuck under high force
Pros and Cons of Engineered Compound Plywood Board
Advantages of Blockboard
- They are light-weighted, and hence very mobile.
- They are commonly used for doors due to their lightweight
- It is an affordable and cheaper alternative to plywood
- Mainly resistant to warping or bending
- They are robust and durable
Disadvantages of blockboard
- Weaker than solid wood
- Nail Holdings may get weaker after a certain time
