What is Plywood? Types of Plywood

Plywood is an engineered wood product. It is made by gluing individual layers of plies (called veneers) over one another. These individual veneers are in turn obtained from logs by rotating them and peeling off thin layers from the logs.

Plywood have several important benefits over wood,  it reduces the tendency of wood to split when nailed at the edges; it reduces expansion and shrinkage, providing improved dimensional stability; and it makes the strength of the panel consistent across all directions. There are usually an odd number of plies, so that the sheet is balanced and this reduces warping. For same thickness, plywood made of more number of plies is stronger compared to plywood made of less number of plies.

MR Grade Plywood 

It stands for moisture resistant grade.  It conforms to IS 303 standards. It is used in the interiors application where the water exposure is almost nil or less eg living room wardrobes or furniture. The glue that is used between the layers of the plywood is urea formaldehyde

BWR Grade Plywood

It stands for boiling water resistant grade. It conforms to IS 303 standards. It can be used in interior or exterior application where water exposure is slightly more eg kitchen cabinets or bathroom cabinets. The glue that is used between the layers of the plywood is phenol formaldehyde.

BWP Grade Plywood 

It stands for the boiling water proof grade. It conforms to IS 710 standards. It can be used in the exterior application or wet areas where water directly comes in contact with the plywood.  The glue that is used between the layers of the plywood is resorcinol phenol formaldehyde

Gurjan Plywood 

Gurjan plywood has all the layers of Gurjan ply in it. Gurjan is hardwood and is red in colour, so all the layers of the plywood will look red. It has more strength compared to other types of plywood but at the same time it is more costly

Redwood Plywood 

Redwood plywood has all the layers of Redwood ply in it. Redwood is hardwood and is red in colour, so all the layers of the plywood will look red. 

Eucalyptus Plywood 

Eucalyptus plywood has all the layers of Eucalyptus ply in it. It is a kind of hardwood. 

Poplar Plywood 

Poplar plywood has all the layers of Poplar ply in it. It is a kind of softwood and is white in colour. All the layers of Poplar ply are white in colour. Since all the layers are of softwood the strength of poplar plywood is slightly less compared to the other types of plywood. It is less costly compared to other plywoods.

Commercial Plywood 

It is an economic range of plywood which can be used for the budget projects. It can be used in office spaces, modular furniture, partitions, panelling, indoor spaces etc.

Waterproof Plywood

As the name suggests this type of plywood offers excellent waterproofing qualities. It conforms to IS 710 standards and it can be used where water comes directly in contact with the plywood. 

Flexible Plywood

It is a special kind of plywood that can be easily bent without breaking it into pieces. It’s very useful for creating any kind of furniture that needs to have curved surfaces. 

Shuttering Plywood

Shuttering Plywood is highly dense plywood with a smooth film coating on both sides of the faces and is used primarily for cement formworks during construction. Mould is prepared out of shuttering cand cement is poured in between. As soon as the cement dries, it takes up the form of the mould and then mould is removed and reused. There is a thin red coloured film on the top of the shuttering plywood. 

WPC Plywood

It is a composite material which constitutes of waste wood fibers and thermoplastics. They are mixed together to form a base material possessing thick consistency. It is then further extruded and moulded to different required shapes and sizes. They are used for railing, fences, windows, doors, flooring, outdoor and other indoor requirements. They are also used for making window frames and designer furniture too. 

In India, plywood market is unorganized sector which comprises of different types of plywood. On one hand there are branded plywood like Green plywood, century plywood, Archid plywood, Kajaria plywood, Duro plywood etc.  and on other hand there are lot of local plywood brands available. Be careful while buying the plywood. We at Plymart guide all our customers in buying the right plywood. Plymart is one of the best plywood suppliers in Ahmedabad.

If you are constructing your home or office or if you want to know more about how one should select the plywood than following is the complete guide on how to select plywood. 

  1. Identify the application
    • If you buying plywood for furniture in dry area like bedroom, living room or study room than consider buying Commercial or MR grade. 
    • If you are buying plywood for furniture in kitchen or bathroom, than consider buying BWR Grade or Waterproof grade. 
    • Make a list of your plywood requirement as per your usage and then order accordingly.
  2. Check for ISI Certification
    • Best Quality plywood is always ISI certified. Commercial, MR or BWR Grade Plywood is IS:303 and Marine or Waterproof Plywood is IS:710.
    • Always look for the CML number underneath the ISI mark. Plywood manufacturer has a unique CML number which helps to identify the plywood manufacturer. 
  3. Check for the Gurjan Face and Full core full panel mark
    • Gurjan is one of the best face veneers used for the plywood. Preferably your plywood should have the Gurjan Face veneer on the top of it. 
    • Plywood which is full core full panel will not be prone to splitting when a nail is hammered. 
  4. Check Plywood Sheet Physically
    • Check whether the plywood face is proper or not. If the plywood has recon face than laminate will not get easily glued. You can put your nail on the face and try to remove it manually. If the upper face comes out easily than plywood is not good for application.
    • Check whether the surface of plywood is smooth or not. If there is some waviness than it not good for the application. 
    • Check all the four corners of plywood and ensure that it has no thickness variation. Glance through the entire lot of plywood laying at the warehouse and check whether the sheets are having uniform thickness or not. 
    • Check the sides of plywood and make sure that core layers are visible as straight lines without core gaps and much overlapping. 
    • Check Weight of plywood by lifting from one side. Heavy weight plywood has always more density. 
    • In 18 mm and 12 mm check whether the plywood sheet is straight or bend. 
  5. Get a small cut piece sample from the lot
    • Ask the plywood supplier to cut a small sample piece from the entire sheet and give. 
    • Don’t rely on trade samples. They are always good. Ask for the sample from the actual lot of plywood. Get the sample piece diagonally cut.
    • Check that it should not have too many core gaps in between. Some amount of pin hole gaps (2mm – 3mm) are allowed but too many of those should serve as a warning sign.
  6. Nail Holding Capacity 
    • The strength of a plywood panel is predicted on its capacity to hold a nail while being used in furniture. 
    • Before buying a ply, ask your dealer to hammer in a nail (14” x 1.5”) into the side profile of a plywood sheet. If the layers split on nailing, the bonding isn’t strong enough and will not work for furniture work.
