These softwood strips are located aspect to side and sandwiched between veneers of hardwood. Blockboards are similar to plywood and higher than particle board and medium density fiberboard (MDF).

Blockboards are a really perfect creation fabric to make cabinets, doors, panelling and partitions.
Generally, there are two primary grades of blockboard to be had
MR Grade (Moisture Resistant) and
BWP or BWR Grade (Boiling Water Proof or Boiling Water Resistant)
MR grade blockboards discover their applications by and large in internal regions that encompass door center, partition, paneling and ceiling, etc. Some very special moisture resistant glues are applied of their manufacturing technique. These forums also are referred to as interior grade blockboards.
2.BWP or BWR Grade:
BWP grade blockboards are engineered through utilising resins which have excessive stage of resistance to boiling water. These boards are closely used for utility in prefabricated houses, coaches for railways, our bodies of buses and kitchen, and many others. Here, they are probably be exposed to high humidity levels, proving them perfect for external use. BWP grade blockboards also are referred to as outside grade blockboards.
There are groups that manufacture water-proof blockboards in India apart from the above versions, making them available thru their sturdy supplier presence throughout the united states of america.
Advantages of Blockboards-
Very tons lighter in weight when as compared to plywood.
Easily transported to the stop place
Cheaper than plywood reducing the fee of interiors
Stiffer and resist the bending in middle
Majorly used for making lengthy pieces (i.E. > five ft) of furniture
