Boiling Water Resistant is similar to Boiling Water Proof but this terminology is conventionally used for blockboards, and not for ply. It is easy to confuse the two, therefore look out for the BWR stamp by the manufacturer. It can similarly be used for furniture in kitchens, bathrooms, outdoor areas and for wardrobes if they back external walls.
Medium Density Fibre Board is also a type of fibre board, which differs intrinsically from ply but has a higher density than Low Density Fibre Board. It is a dry formed panel manufactured by applying high pressure and heat to wood pulp, and not sheets of wood veneer.
