While to the casual observer it seems like most of the doors
around them are plywood doors, this is just not the case. The preferred choice
for making wooden doors these days is 'Flush Doors'. These Flush doors have hard
rectangular slabs of softwood on the secret set end to end, and enclosed on
both side through a very thin coating of ply round 2.5 mm thick.
Ideally talking, a door can be built entirely out of
plywood, but this is infrequently complete in rehearsal. The motive for this is
that long fragments of plywood are actually to bend at the center. On the other
side flush doors do not frequently twist in such a manner.
Moreover plywood is regularly complete from hardwood which
makes the sheet is quite weighty. Later plywood doors will be much heavier than
flush doors. Thicker doors can be much harder to transport and connect, and to
operate in everyday use.
The third point of evaluation is material cost. Plywood is pricier
than block boards, and later the cost of Plywood doors made totally out of
plywood will be much more than the cheaper flush doors.
Some word about Flush Doors
Flush doors are of two types. Solid core and hollow core. As
the name suggests Solid core flush doors have solid blocks of wood inside, and
the hollow core doors are hollow on the inside with only a supporting honeycomb
structure. Solid core doors are stronger and have better sound proof
While most doors of houses are made from solid core flush
doors, the hollow core doors are considered suitable for making partitions.
Entry doors of houses are usually made from BWP grade flush
doors. As per the Indian grading system, the acronym BWP stands for Boiling
water proof and these are of an exterior grade waterproof quality.
Many of the major plywood companies in India also
manufacture ready made flush doors, that are ready to install and don't need
any further finishing. Such doors are available in a variety of attractive
designs and colour shades. Good quality wood veneers can also be used as an
overlay to enhance the look and feel of doors.
To summarize this article, I would say that all-plywood
doors are a rarity, while flush doors are currently the in-thing.
