What is BWP and BWR grade Plywood?
Many people even some plywood pursuer can not identify BWP and BWR.BWP and BWR are two different grades used for waterproof plywood. Many dealers and retailers often used these two terms together to confuse buyers. Let me clear this confusion for all buyers and especially Home owners who are the victims most of the times.
Firstly let me explain what these terms stand for, BWR denotes boiling water resistant grade plywood. WhileBWP stands for boiling water proof grade plywood. Well technically there’s very small difference with regards totechnology and treatment used to manufacture each of these plywood. The glue used to manufacture each of these is synthetic plastic resin i.e. phenol formaldehyde which is said to be better than urea formaldehyde resin used to make MR grade commercial plywood.
To simplify, BWP and BWR are plywood standards. These standards are set by government. For factories manufacturing plywood, they need to meet assured quality, tests. Also the process of manufacturing too is customary. And therefore you have set standards for each BWP and BWR grade plywood.
BWR plywood can also be made in Garjan wood, which is an imported wood. You also have BWR grade plywood made from poplar Indian species wood.
In Industry, BWR grading is used to grade plywood while BWP grade is used to mark block-boards or ply-boards.
