CE/ Green Construction Certified Rockwool sandwich panel - Acous® sound absorption and insulation sandwich panel - Indoor noise reduction 1/3- Rockwool sandwich panel manufacturer

Acous^®

Wiskind uses professional-grade acoustic spectrum analysis instruments, according to the acoustic characteristics of materials, through precise acoustic measurement and full study of human hearing system, the introduction of Acous® sound absorption and insulation sandwich panel, when only used in large and medium-sized factory walls, can achieve indoor noise reduction of about 1/3, sound insulation increase by 100%, at the same time with good corrosion resistance and mechanical properties. Become the first choice for noise reduction in industrial buildings, protecting occupational health and safety.

Sound absorption property, indoor noise reduction by 1/3

The experimental results show that when the test range is 100-5000Hz, the average sound absorption coefficient of Acous^® is 0.64, and the noise reduction coefficient NRC is 0.75. Excellent sound absorption performance, indoor noise reduction by 1/3 after application; Noise reduction coefficient of common metal plate NRC=0.15, lower than the classification range; Acous^® Noise reduction coefficient NRC=0.75, belongs to the II level, much higher than the noise reduction coefficient of ordinary metal plate; Noise reduction performance is excellent, close to the plate rock wool noise reduction coefficient NRC=0.85.

Sound insulation performance, the sound insulation is enhanced by 100%

Experiments show that the sound insulation performance of Acous^® is 100% higher than that of ordinary sandwich boards when the high-frequency noise transmittance is less than one in 10,000.

Durability

PE coated punching plate after 480h neutral salt spray, punching position no corrosion phenomenon, meet the requirements of indoor use.
