Firstly let’s understand what is Plyboard?
Plyboard is a wood based panel, made of a core of softwood stripes that are glued together. These stripes are usually 28 mm wide placed edge to edge that is sandwiched between two veneers of either softwood or hardwood glued under high pressure. Actually Plyboard isa local term given to Blockboard. Blockboard is used to denote plywood mainly in industries and factories.

Plyboard & Plywood
Just like blockboard, there are several other terms relating plywood not known by all home owners. For example Plyboard or blockboard is often confused with term plywood and vice versa. Let me clear this misconception for all those home owners. Plywood and Plyboard are two different terms.

ii. Bloackboards or Plyboards are often therefore light in weight as compared to plywood.
iii. Also plywood is of superior material as compared to blockboard. .
iv. Externally both appear to be similar. One can look for the board edge to differentiate betweenthe two. Plywood board edge will show layers of sheets glued to make plywood. While plyboard edge will have a solid wood appearance.
Areas where plyboard is ideal over plywood
Plywood is often used to make furniture’s but it has a tendency to sag or bend if used to cover huge areas. Plyboards are ideal for such areas. Plyboard is often preferred over plywood for areas where longer pieces of wood is required to make furniture like long tables, benches, panels, partitions, etc.
