5 feathers of commercial plywood

1. It is an Interior grade plywood, meaning its for indoor use.

2. It is not waterproof. Though the word 'Moisture Resistant' (MR) can confuse many people into thinking that its waterproof, that is not the case. Being 'moisture resistant' is not the same as being 'water resistant'. While it is true that moisture resistant plywood can withstand some amount of moisture and humidity, it cannot be said to be waterproof. On the other hand, the exterior BWR grade plywood is waterproof.

3. In the case of Commercial plywood, Urea melamine formaldehyde resin is usually used for glueing the individual plies together. On the other hand, BWR grade is made from phenol formaldehyde, which is a synthetic plastic resin.

4. MR grade Commercial plywood is the most widely used type of plywood for making furniture for homes and offices. Drawing room furniture and paneling work, as well as bedroom furniture is almost always made using Commercial ply. However in those cases where the furniture is likely to get wet, using BWR grade ply is considered to be better.
