3.Acoustic panel technical data for reference:
 

1)Insulation performance:

Core material	Fire level	Panel thickness	Thermal conductivity(λ)	U value
				W/m².K
Rockwool	A1 According to GB/T 23932-2009	50	0.036 W/m.K	0.68
		60		0.58
		80		0.44
		100		0.35
		150		0.24

Note:This is calculated based on steel sheet thickness:0.50mm.

2)Loading capacity:
 

Panel thickness	Steel sheet thickness for both side	Panel weight	Span type	Span distance
				1000	1500	2000	2500	3000
		Kg/m²	mm	Max load capacity kg/m²
50	0.50 mm	14.3	continuous span	695	518	408	328	260
			Multiple span	708	531	411	329	262
60		15.3	continuous span	805	532	416	351	282
			Multiple span	813	542	422	352	285
80		17.3	continuous span	833	548	429	360	292
			Multiple span	840	560	435	364	295
100		19.3	continuous span	851	562	436	368	298
			Multiple span	857	570	442	372	299
150		24.3	continuous span	878	578	448	377	303
			Multiple span	882	583	453	380	305

Note:This is calculated based on steel standards Q235,and rockwool density is 100KG/M³.

3)Detection of sound reduction index and grades of sound insulation performance:

1/3 octave center frequency (HZ)
Frequency	100(HZ)	125	160	200	250	315	400	500
Average R(dB)	29.5	30	35.5	33	24.5	33.5	34.5	34.5
1/3 octave center frequency (HZ)
Frequency	630	800	1000	1250	1600	2000	2500	3150
Average R(dB)	35	37.5	39	39.5	43	41.5	42.5	43.5
Sound reduction index	Rw(C;Ctr)=36dB

Note:This test is based on panel thickness:60mm,rockwool density:120 kg/m³,and external sheet thickness is 0.75mm,and internal sheet thickness is 0.50mm.
 

4.Acoustic panels application and advantages:
 

The soundproofing panels can control and reduce the noise in industrial buildings through its rock wool insulation and perforated surface,then it could create a comfortable space in the gym and cinema by ensuring perfect sound insulation.Also for the industrial buildings or power plant which need sound insulation.
The acoustic rockwool sandwich panels key advantages:
☆ A1 level fireproof function;
☆ Excellent sound insulation;
☆ Good thermal insulation.
 

5.Packing & Loading:

All the sandwich panels are with PVC films on surface to protect,and with sealing end of panel edge to avoid crashing.And then panels will be packed in bundle,then loading in the containers.

7.Other notes:

1. After the materials arrive at site,please check the quantity of each item carefully and see if any transport damage happened,according to the delivery list. If you found out any missing or panel damage,please check if it is indicated on the invoice or not,also immediately notify the relevant service department of Yumi steel.
2. The small piece of material,for example fasteners,connecting pieces and sealants should be placed in safe place,it's better to be locked,in case of theft.
3. Please don't use the dirty gloves to handle and install wall panels and edge trims(flashings),especially galvalume material and edge trims,in order to avoid the dirty appeared on wall panels and edge trims surface,and it's hard to clear and will have effects on aesthetic.
4. All the parts that need sealants should wipe the attachment surface clean,to make sure there is good adhesion on color steel.The glue joint should be full and dense to avoid water leakage.
5. The PVC films on panels,please peel it off within 3 ~ 4 months,after shipment.Otherwise it will have chemical reaction and make it very difficult to peel off.
6. During the installation process, wall panel maybe damaged by collision and friction with the scaffold, column, brick wall,etc.So please be careful about this point.
7. During the on-site cutting process of wall panel, the bottom surface of the cutting machine should not be in direct contact with the color steel surface.It's best padded with thin plywood on the panel,then cut.The burrs on the cutting end need to be removed and installed in time.
8. Iron scraps are generated after cutting and drilling holes,and these iron filings on panel surface need to be cleaned.These iron scraps must be cleaned up in time and must not be left overnight.Iron filings can rust in a humid environment. The rust spots are verified to be removed after the surface of the board is formed, and the paint surface or even the substrate may be damaged for a long time.Similarly, other cut-off color steel heads, iron bars pulled by aluminum alloy steel nails, etc. should be cleaned up in time.
9. After the daily installation work is completed, all the debris left on the site must be cleaned up.
