We are able to offer engineered wooden doors in the following species:
(listed in alphabetical order)
Our supply of doors comes from modern and reliable manufacturers that have the
equipment capable of producing designs. We are able to cater for higher complexity
models upon request.
We can also supply pre-finished doors, as well as engineered (or solid) frames to
match the doors.

What are Engineered Doors?
Engineered doors are doors made with real wood veneers (commonly 0.6mm thick)
laminated onto substitute core substrates. This gives the door the appearance of a
solid wood door.
There are many possibilities in constructing an engineered door, and we have the
necessary experience and knowledge to produce them well. We are one of the
pioneers in innovating the production of engineered doors, and have introduced
several world standards practises. Our processes and methods, working closely with
our supplier, are continuously evolving to produce better and more competitive
The biggest weakness in solid doors is timber stability, which is highly dependent on
the specie of wood used and the surrounding environment or climate. On top of that,
the quality of drying of the wood, as well as timber matching affects the integrity of the
solid door. Poorly dried timber or substandard construction may result in the timber
splitting, or joints comping apart pushed open by expanding panels. Also, long length
components especially the stile is susceptible to warp causing the door to bow or twist.
Engineered construction reduces, if not eliminates, this problem by using dimensionally
stable core such as particleboard or MDF (which forms bulk of the mass of the door).
When solid wood core is used, they are typically fingerjointed from small, narrow strips
to 'break' the grains of the wood so that any movements in an individual strip are
inhibited by other strips.
2. Improved Door Characteristics
When we want to improve a certain characteristic of the door (compared to a solid
door), we use the engineered method. Here are a few common points:
For timber species that are inherently expensive or scarce such as cherry, walnut or
teak, the engineered solution allows consumers to have doors that are affordable by
replacing the bulk of its mass with cheaper commodity-priced core material.
ii) fire resistance
We are able to increase fire resistance of doors by including fire-resistant material
under the veneer. Our supplier has several designs tested to British Standards.
iii) sound and heat insulation
Similar to fire resistance, we can select the type of core to use to improve its sound
and/or heat insulation characteristics.
For certain applications such as use in office partitions and high-rise buildings in
earthquake-prone areas, heavy solid wood doors are not desirable. Engineered doors
can be tailored to weigh less than a similar sized solid door while maintaining a similar
appearance, either by using a lighter wood substrate, or innovative use of foam core.
Engineered construction uses less solid timber than a solid door equivalent. A 40mm
solid piece of timber is able to yield over 60pcs of 0.6mm sliced veneers. Only narrow
timber strips are used where it's visible such as the edges as well as the profiles. Since
substitute substrates such as MDF and chipboards get their material from plantations,
the volume of actual forest timber used in an engineered door is much lower.
Even when using a solid hardwood core, we typically use rubberwood, which comes
from rubber plantations. Also, since the core will be covered by veneer (thus not
visible), lower visual grade timber can be used, which otherwise in a solid door
construction has to be discarded.
We are able to supply FSC® certified engineered doors.*

How Is It Made? (briefly)
A typical engineered stile-rail door construction is made using particleboard as the
primary core for the stile, rail and mullion components. These core components are
then laminated with timber strips matching the face veneer species required, before
the face veneer is being pressed onto the surface of the door using a hot press.
Fielded or sloped panels usually use MDF as its core substrate. Veneer is pressed
onto the sloped panels using a bladder press (also known as a membrane press)
under heat and pressure.
Narrow glass bars are typically solid timber strips.
The doors are assembled together using a dowelled system.
The construction of different models and designs differ one from the other, so our
processes are constantly tweaked to produce different types of models.
If you have a specific model in mind, please do not hesitate to contact us with the
design for a quote.
