EXCELTONE (DL series)

EXCELTONE (DL series)– Double Layer / Tongue & Groove System
Key Attributes
Features & Benefits:• EXCELTONE (DL series) is a high density tongue and groove mineral fibre ceiling tile

with a white painted finish designed for direct fix applications to new and existing
gypsum board or timber battens.
• This negates the need for an exposed grid enhancing its highly visual appeal. No
additional painting required.
• EXCELTONE (DL series) is a mid-range tile with superior noise absorption andefficient thermal insulation (more than 6 times of gypsum board), while resisting soundtransmission more effectively than glass fibre products.
• Due to its high density and fine grained substrate, Daiken can achieve unique and highquality detailing in their tiles. These tiles have outstanding fire resistance.
• With invisible ceiling grid, concealed appearance and can integrate service installations
such as lighting, ventilation and smoke detectors.
• Non-Asbestos

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.
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.

Benefits of Conventional Ceiling Method

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

Benefits of New Ceiling Method

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

Earthquake resistance and workability improvement with comfortableindoor environment maintained

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.

NOTES FOR INSTALLATIONSPECIFICATION GUIDE

Trouble-free installation, satisfactory ceiling finish and the long life of DAIKEN
mineral acoustical materials can be ensured by observing the following
recommendations.

I SCOPEJOB SITE STORAGE
DAIKEN mineral acoustical materials should be stored in a dry and clean area
protected from possible damage by rain, snow, and excessive moisture. If theseacoustical materials are exposed to large variations of humidity or temperature,swelling and shrinkage can result. The acoustical materials should be also beprotected against possible impacts and abrasions and kept at least one meter awayfrom walls.
Stack the materials flat on a level floor with protective panels or sheets between
the materials and the floor.

HANDLING
Acoustical materials should be handled with care to prevent impact or damage toedges, ends and surface.
Handle these materials with clean hands or gloved hands.

INSTALLATION CONDITIONS
A.	Allow wet work, such as plaster and concrete work, to dry completely.
B.	Water-proofing and flashing work should be completed. Windows and doors
should be in place and glazed.
C.	Conduits and duct work should be completed.
D.	Care should be taken to place air-conditioning vents and other mechanicalfixtures conveniently within the suspension system.
E.	Installation should be done when relative humidity is not greater than 80%.
(except EXCELTONE MR series in thickness of 5/8" and 3/4"). Avoid installing thematerials if relative humidity exceeds 80%. Daily checks of humidity conditions
during the installation period are suggested.
F. There should be adequate ventilation in the installation area if the building is newand humid conditions prevail. Before beginning installation, make certain that
there is no condensation on the wall surfaces. Also, the heating system should be
operating if the weather or installation area is particularly cold.
G. Damaged or soiled materials should be replaced.

INSTALLATION
Installation should be in accordance with our specifications and recommendations.

GENARAL MAINTENACE
CLEANING:
Dust and loose dirt can be easily removed with a brush or a vacuum cleaner. Takecare to clean in one direction only. This will prevent dust from being rubbed into
the surface. An alternative method of cleaning is with a moist cloth or a sponge
dampened in soapy water. The sponge should be wrung dry. Use gentle strokes towipe surfaces. After washing, the soapy film should be wiped off with a cloth orsponge slightly dampened in clean water.
REPAINTING:
DAIKEN mineral acoustical materials can be repainted by spraying, brushing, or rollcoating without appreciable loss of acoustical efficiency. Dust and dirt should bethoroughly removed from the ceiling surface before repainting. Care should be taken
to avoid applying paint thick enough to cover the perforations or fissures in thematerial. It is a good idea to test the paint on a small area or on a scrap of material,or surface stains bleed through the paint film., choose another paint. Regardless ofthe method of paint application employed, a good grade of paint from a reputablemanufacture should be used. Acrylic, vinyl, latex, or alkyd paint for interior use may
be applied.

A.	The installation of all acoustical work covered in this section shall be a qualified
acoustical contractor.
B.	T he acoustical contactor shall furnish all labor, materials and equipment
necessary to complete the acoustical work in accordance with this section of thespecifications and the applicable drawings.
C. Substitutions will not be permitted for materials and method covered in thissection.

II GENERAL CONDITIONS
A.	DAIKEN mineral acoustical materials shall not be used as support for or carry theloading of additional insulation, lighting, fixtures,etc.
B.	The acoustical contractor shall be resposible for the examination and acceptanceof all surfaces and conditions affecting the proper installation of this materials,
and shall not proceed until all unsatisfactory conditions have been corrected byothers.
C.	All acoustical materials shall be installed by accepted installation practices.

III INSTALLATION
A.	The acoustical contractor shall furnish and install DAIKEN mineral acousticalmaterials in strict accordance with DAIKEN' s recommendations in order toprovide a satisfactory installation.
B.	The acoustical contractor shall furnish and install the metal suspension system
as manufactured by (specifyed manufacture) in strict accordance with the
manufacture's recommendations in order to provide a satisfactory installation.

more, or with a DAIKEN's original color.
D.	The acoustical material shall have sound absorption coefficients of ( ) andtransmission losses of ( ).

SELECTING LIGHTING
When selecting any type of lighting, it is always advisable to consider the effect itwill have on the appearance of an acoustical ceiling. The most functional of all typesof lighting is the flush, recessed fixture commonly used with suspended acousticalceilings. Where light from fixutre, cove lights or high windwos strikes the surfaces
at a shallow angle, even slight unevenness of joints may result in unsatisfactory
appearance. Under such conditions beveled edge materials should be used in
preference to square edge materials, and should be installed with considerable care.
