Rock wool board (rock wool sandwich panel)

Rock wool sandwich panels use an automated production process, where rock wool and steel plates are compounded and formed in one go within the factory, completely changing the traditional on-site compound working mode.

This industrialized production not only ensures the stability of product quality but also achieves the engineering objectives of high quality, efficiency, reliability, and safety.

This product's technology is mature and has been widely applied and validated in Europe.

Rock wool sandwich panels fully utilize the unique properties of rock wool core materials, demonstrating excellence in the following aspects:

1. Excellent fire resistance performance
The materials, production processes, and formulation system used in the product endow it with excellent fire resistance, with fire resistance performance exceeding 1000°C. It strictly adheres to the standards set by the International Organization for Standardization (ISO), British BS, and German DIN, complying with multiple fire protection specifications. The results of the fire resistance limit tests are as follows:

50mm thick rock wool sandwich panel: REI 30
80mm thick rock wool sandwich panel: REI 60
100mm thick rock wool sandwich panel: REI 120
2. Efficient thermal insulation
Based on the excellent characteristic of rock wool core material with a thermal conductivity as low as 0.043 W/㎡K, through scientific calculation and appropriate thickness configuration, rock wool sandwich panels can effectively block heat transfer, achieving a long-lasting and stable insulation effect.

3. Significant sound absorption and sound insulation effects

Sound absorptionThe rock wool sandwich panel has a wide frequency sound-absorbing performance, with excellent sound absorption effects. According to the ISO 35/85 standard, its sound absorption performance reaches DELTA LA=15.7dB(A).
SoundproofingIt has a significant noise reduction effect on noise transmission, especially suitable for places with strict noise reduction requirements, such as around airports. The use of rock wool roof panels can also greatly reduce indoor noise generated by rain and hail striking the roof. According to the ISO 717/82 and UNI 8270/7 standards, the sound insulation performance of sandwich panels with 120 kg/m³ rock wool can reach RW = 29-30 dB.
Advantages of lighting panels: Due to their smooth appearance, lightweight and high strength, high light transmission rate, corrosion resistance, aging resistance, flame retardance, accurate cross-sectional dimensions, water resistance, customizable cutting length, easy installation, and a service life of up to 15-25 years, they are highly favored by users.
