4. Noise Reduction Coefficient (NRC)

NRC is the average sound absorption while the sound strike the panel on one side and

transmitted from the other side.    NRC is a single number ranging between 0 – 1.0

measured at frequency 125Hz, 250Hz, 500Hz, 1000Hz, 2000Hz and 4000Hz  under ASTM C 423

standard.

Frequency (Hz)	Noise Reduction Coefficient (NRC)
	9mm	12mm	15mm
125	0.29	0.33	0.36
250	0.26	0.26	0.28
500	0.38	0.50	0.52
1000	0.62	0.63	0.64
2000	0.78	0.80	0.80
4000	0.95	0.95	0.97
Average NRC	0.48-0.53	0.53-0.57	0.55-0.60

 

5. Ceiling Attenuation Class (CAC)

CAC is the ability of a ceiling tile to prevent the transmission of sound between rooms with a

common ceiling space.    Therefore, it rates a ceiling’s efficiency as a barrier to airborne sound

transmission between adjacent closed offices under ASTM E 413 standard.

Frequency (Hz)	dB (Decibel)
	9mm	12mm	15mm
125	17	18	20
250	20	28	29
500	23	34	36
1000	28	37	39
2000	32	38	40
4000	30	38	40

 

6. Installation Guide

Place square edge or reveal edge DAIKEN board on T-bar ceiling metal stud.     Make sure the system

of DAIKEN board and metal stud must be the same.    For example, Gypsum system of DAIKEN board

must be used with gypsum system of metal stud.

* See detailed explanation on Topic 2. System Explanation above.

 

7. Why have to use DAIKEN acoustical ceiling tile?

– ASBESTOS FREE: DAIKEN is asbestos free products.  Use of Asbestos, can cause

cancer and an adverse effects on the human body and the environmental.

– OUTSTANDING FIRE RESISTANCE: DAIKEN is not only non-combustibility, but also

less likely to emit toxic gas or smoke, or to melt, break, or become deformed under

normal fire conditions, protecting ceiling areas from fire.

– DAIKEN has modern and timeless pattern such as Travertine Delica, New NDF

and New Constellation

 

8. Guarantee

DAIKEN guarantees sagging for 10 years after installation under below conditions:

8.1 DAIKEN must be installed after cement and gypsum work has been dried and finished.

8.2 DAIKEN must be installed after work has been done such as door, window and

electronic wire installation.

8.3 DAIKEN installation shall be done under the conditions of relative humidity not more

than 80%

8.4 DAIKEN shall be installed at good ventilation area.
