* A flush door has a basic structure composed of solid blockboard core,
vertical stiles, and horizontal rails that create a pre-fixed frame.
* The blockboard is composed of wooden strips that are placed edge-to-edge
and sandwiched between veneers, then bonded under high pressure and t
emperature using a synthetic resin.
* So in a simpler term, it is a door that is made of a timber frame covered with ply
from both the sides and then the hollow part inside is filled with rectangular
blocks of soft wood.
* Then a decorative finish is given by fixing veneer on the top.
* A flush door is so called because it has an entirely smooth surface.
* If water were to be splashed on its surface, it would simply flow off its surface without accumulating.
