Plywood

Plywood is an engineered wood sheet material made up of fine layers or flimsy strands of wood veneers. It is one type of manufactured board which can be described as a mixture of Medium Density Fibreboard (MDF) and Chip Board (Particle Board). Plywood has become popular through this decade because it’s relatively low moisture content which makes various tasks easy to perform with this. Mostly for outdoor uses plywood has become very important to use.

IS 710 BWP GRADE

As the name indicates, this type of plywood is meant for marine applications i.e. where flowing water or excessive exposure to water is there. Technically, this is called BWP (Boiling Water Proof) plywood. In trade circles, this is also called 710 plywood, named so after the IS standards for this type of plywood (BIS 710). This is the true water-proof plywood and is made using water-proof phenolic resins.

The acronym BWR stands for ‘Boiling Water Resistant’. It is an exterior grade waterproof plywood, that is better than MR grade plywood. It is the preferred choice of material for making those pieces of furniture that are likely to get wet.

MR GRADE PLYWOOD

MR stands for ‘Moisture Resistant’ plywood. It Is also known as Commercial plywood. It Is an Interior grade and meant for making furniture that will be used indoors. As mentioned earlier, MR grade plywood defies moisture and humidity. But this doesn’t mean it can resist water and exhibit waterproof properties. Yes, it does not possess the ability to withstand the effects of water contact for a long time. If you are in need of waterproof plywood, you can opt for BWR grade plywood which is highly water resistant.

BLOCK BOARD

Blockboard is a relatively new type of engineered wood which is now extensively used in making furniture as substitute of plywood. Blockboard consists of a core made of softwood strips between the two layers of wood veneer. Blockboard is used in making bookshelves, benches, doors, shelves, tables, wall panelling and partition walls. Before buying blockboard, a homeowner must be aware of blockboard properties like weight, density, durability, strength, etc. Here we have tried to give brief information on various blockboard properties.
