Recently, Luoyang, Henan is well-known because its fire accidents which up to 4 times for a month.

May 29th,the outer of skyscraper on Jiudu Road caught fire and the fire raged from the third floor to top floor.

The fire agent organized more than 10 fire vehicles and several ambulances for the ferocious fire, they extinguished the fire eventually and without injury.

Several fires and fast spread are closely related to the combustible material of external wall insulation. The material should have worked for energy saving and comfortable living environment, but it pushed the fires.

Absolutely, that is not the case. According to Code For Design Of Building Fire Protection GB50016-2014. Is insulation material really so weak when there is a fire?

There are different demands for burning characteristics for enclosing insulation material of different architectural style and building height,

For building with assembly occupancies, the burning characteristic for its external wall insulation should up to Class A1, combustible material is restricted?for?use.

Indeed, the product quality varies in the insulation industry, fake commodities and non-conformity products without any quality guarantee or relevant certificates results in hidden?dangers and disturb the industry development.

Every product has its standard from production to sales, from appearance to quality, under strict control.

Product authentication for different countries not only the pass for local market sales, but also the important index for goods quality and safety to customers.

Underwriters Laboratories Inc. from America tested burning characteristics of our Yinghua rock wool board according to UL723 standard, the product passed the test perfectly, met the standards totally and we got the UL certificate.

UL is short for 'Underwriter Laboratories Inc.', an independent, non-profit, professional non-governmental Institution with highest authority for safety tests and safety?appraisal.

The institution was founded for test for safety certification and Safety Production License, its final purpose is to provide very safe products for the market and to make efforts to body health and property safety.

UL723 safety standard is Test for Surface Burning Characteristics of Building Materials of North America, testing approach is as follows:

The ignition source is 2 gas blow lamp below the sample(the distance is 190mm) and parallel to the fire end(the distance is 305mm) in laboratory, the output is 5.3MJ/min. Classify the materials according to FSI(and smoke generation).

The smaller the FSI value, the safer the building. For skyscraper and passageway, FSI must less than 25.FSI between 25-100 is enough for places that are not so high-demand for fireproof. FSI above 100 fails to comply with flame retardance.

UL723 fire test classified the materials into three types according FSI and smoke generation named A,B,C. Yinghua rock wool board is Class A.

UL723 Class A: FSI between 0-25 with smoke index less than 450.

UL723 Class B: FSI between 26-75 with smoke index less than 450.

UL723 Class C: FSI between 76-200 with smoke index less than 450.

UL certificate guarantee product quality and safety, only few domestic rock wool company passed the test. Yinghua rock wool is certificated by CE,FM,TUV and other test institutions in the field of architecture.

The company is responsible for construction of domestic rock wool application and it leads the industry all the way.

To Yinghua rock wool, certificates mean approval of product quality from international institutions. To the company, certificates mean deeply mission and responsibility to customers.

Warm notice: Strict control and outstanding quality for Yinghua rock wool, pls purchase from official channel and you can check it from our anti-counterfeiting system, here is the link: http://qc.cnabm.com:8300/.

Resist fake commodities, start from me!
