About MDF
The DAIKEN Group offers two types of MDF(Medium Density Fiberboard), Hardwood and Softwood types.
Hardwood Type

Softwood Type

Product Thickness: 2.5 to 21.0 mm

Product Thickness: 1.8 to 30.0 mm

CabinetExcellent Dimensional Stability

Light-colored Surface suitable for a variety of surface decoration

Little dimensional change and a low possibility of warping even under harsh environments (athigh temperature and high humidity) allow wide use in cabinets, wooden fittings, etc.

Laminating this MDF with a translucent sheet has little effect on the decoration surface. In direct
printing masking coat process may be removed.

Superb Water Resistance

Smooth Surface

Little swelling in water or in humid environments allows use in window frames (sash frames),
flooring baseboards, etc. that require resistance to water and moisture.

Long wood fibers provide smooth surface suitable for lamination, coating, and other treatments.

Effective Utilization of Untapped Resources and Stable Raw Material Procurement
W a llTaking advantage of our location in Malaysia, we utilize untapped resources such as residual
wood pieces discharged from sawmills and plywood plants and also utilize plantation trees tostably procure raw materials.

Effective Utilization of Untapped Resources and Stable Raw Material Procurement
One of our plants is located in New Zealand where planned-afforested radiata pine trees areabundantly available. Portions of the trees not suitable for sawing are used as the raw material of
the MDF for stable raw material procurement.

DAIKEN Ceilings are chosen

DAIKEN Ceilings are made from selected mineral rockwool fibers and special binders.

Because the DAIKEN Ceilings has porous properties with a low specific gravity,
they exhibit efficient thermal insulation and sound absorption qualities,
while resisting sound transmission more effectively than glass fiber products.

Daiken Ceiling grid Construction Method for Buildings and Stores

New Technology

Utilizing the know-how of installation method of ceiling system,
DAIKEN has achieved both earthquake resistance andworkability improvement.

Benefits of New Ceiling Method

・High rigidity through the use of grid assembly
・Unitized design for less workload and shorter construction period

F l o ori ng

Benefits of Conventional Ceiling Method

・Flexible design
・Usable for buildings in a variety of applications

Ceiling

After the Great East Japan Earthquake, the Japanese Building Standard Law
was revised to require higher seismic performance for ceilings. However,there was a concern that fulfilling the demand with the conventional
construction method would result in an increase in the construction workload.
To address this issue, DAIKEN adopted a unique new ceiling construction
method that can improve the seismic performance of ceilings in a short
construction period with less workload.
This solution uses a ceiling underlayment material that combines the benefitsof conventional ceilings with those of system ceilings.

●High-rigidity diagonal bracing corresponding to
the unit weight of the ceiling needs to be installed.

Main T-bar

3 to 4 times the conventional
construction workload is needed.

＊Not applicable to some specific ceilings such as curved ceilings

Improved Safety with Light-weightRock Wool Decorative Acoustic Boards

Our new method showed a high seismic performance of 4,000 N withrespect to the allowable ceiling proof stress in the "unit test" (staticpressurization test) designated by the Ministry of Construction (the current
Ministry of Land, Infrastructure,Transport and Tourism.(＊In-house test result)

It is proved in our laboratory test that our rock wool decorative
acoustic boards have a low risk to human life in the event of falls.
■Dummy Head Test Result

Construction workload is reduced by approx.
20 to 30%, compared to when using conventional
ceiling method to improve the seismic performance.

One-push Underlayment Installation
Combined with Excellent Workability
to Realize a Short Construction Period
The new method contributes to the reduction of construction
workload because the number of seismic braces is reduced.
