40-200kg/m3 Rock Wool Insulation Board 1200x600mm for Noise Reduction

Durable And Recyclable Rock Wool Panels Reducing Echoes And Noise Pollution

The safety and non-toxicity of rock wool boards are among their core advantages distinguishing them from many chemical synthetic building materials. This characteristic runs through the entire life cycle of the material itself, production and processing, and long-term use, which can be elaborated in detail from the following dimensions.

Application

With its special structure of internal porous and interwoven fibers, rock wool boards possess excellent sound insulation and noise reduction capabilities, and are widely used in civil buildings, industrial and commercial sites, as well as transportation and special scenarios. In the field of civil buildings, they can be applied to the partition walls and bedroom ceilings of residences and apartments to block the daily noise from neighbors and the sound of footsteps from upstairs. When laid under the floor, they can reduce the transmission of impact noise generated by indoor activities to the lower floor. They can also wrap the indoor heating pipes and fresh air system pipes to reduce equipment noise. In industrial and commercial sites, they are suitable for the walls and ceilings of machinery processing workshops and textile factories to absorb high and low-frequency noise from machine operation, thereby protecting workers' hearing. They can also be used as the wall sound insulation layer in places such as KTVs, gyms and conference rooms to prevent the high-decibel noise inside from disturbing the surrounding areas. In transportation and special scenarios, they can serve as the core filling material for outdoor sound barriers of roads and railways to reduce the impact of traffic noise on residential areas along the line, and can also be used for wrapping the walls of equipment rooms such as generator rooms and water pump rooms to reduce continuous equipment noise.

Advantages

Compared with ordinary sound insulation materials, rock wool boards have significant advantages in sound insulation and comprehensive performance. They have high sound insulation efficiency and can achieve full-frequency noise reduction. Their internal porous fiber structure can effectively "absorb and reflect" sound waves, with a sound absorption rate of more than 80% for high-frequency noise and good blocking effect on low-frequency noise, avoiding the problem of "only blocking high-frequency noise but not low-frequency noise". Moreover, they have excellent fire resistance and are non-combustible materials (combustion performance Class A). They do not burn or release toxic gases when exposed to fire, and maintain structural stability at high temperatures, making them suitable for high-risk scenarios such as KTVs and equipment rooms. They have strong physical stability and outstanding resistance to shrinkage and deformation. In environments with large temperature and humidity changes, they are not prone to cracking and pulverization, and their sound insulation effect can be maintained for more than 10 years without frequent replacement. At the same time, they also have excellent thermal insulation performance (thermal conductivity ≤ 0.044W/(m·K)). When used in building walls, they can achieve both "sound insulation and thermal insulation" functions, reducing the cost and construction procedures of laying separate thermal insulation materials and improving comprehensive cost-effectiveness. In addition, high-quality rock wool boards are environmentally friendly and non-toxic, without harmful substances such as formaldehyde and benzene, meeting environmental protection standards and suitable for scenarios such as residences and schools. They are also relatively hard and easy to cut, able to adapt to different size requirements, and flexible in construction.
