Internal Acoustic Filling Made from Recycled Cotton
The Recycled Cotton Soundproof Panel is made from recycled cotton fibers and is mainly used as an internal acoustic filling material for walls, ceilings, and composite structures.
Its fiber structure absorbs part of the acoustic energy inside structural cavities. This helps reduce cavity resonance and internal sound reflection and can support the acoustic performance of the overall wall, ceiling, or equipment structure.
Compared with recycled cotton panels intended mainly for surface reverberation control, this product places more emphasis on concealed installation inside a structure. It can be positioned within partition walls, equipment housings, and other composite constructions where the acoustic filling layer is not directly exposed in the finished interior.
Semi-Rigid Structure and Reference Performance
The available thickness range is 25–50 mm, with a density of 48–96 kg/m³. The reference Noise Reduction Coefficient is approximately 0.80–1.15.
The material has a semi-rigid structure, making it easier to position during installation. It can fill internal wall and ceiling cavities while providing both sound absorption and auxiliary thermal insulation.
For thermal resistance, the supplied information lists an industry reference value of approximately 3.8 ft²·°F·h/BTU/in for some products. This figure is an industry reference for certain products and should not be treated as the actual performance value of every production batch.
The supplied information also does not provide a confirmed fire-test result for this product. Any fire performance requirement should therefore be checked against the actual available test report rather than assigning a fire rating or certification in advance.
Building, Equipment and Modular Applications
The Recycled Cotton Soundproof Panel is suitable for hotels, apartments, office partitions, meeting rooms, cinema wall structures, equipment rooms, machine rooms, equipment housings, and modular buildings.
Inside building partitions, it can act as a filling layer between board materials and help reduce acoustic reflection within the cavity. Inside equipment rooms, machine rooms, and equipment housings, it can participate in internal sound absorption treatment.
The use of recycled fibers also supports projects that want to consider both acoustic treatment and material reuse. For purchasing, the appropriate thickness and density should be selected according to structural depth, installation position, and the requirements of the overall construction.
Specification Coordination for Project Orders
Anhui Ziyan Fiber Products Technology Co., Ltd. produces fiber products and acoustic cotton materials with a factory setup that includes raw material storage, production processing, finished-product inspection, and an R&D laboratory. The factory is equipped with three automated production lines.
For different wall systems, equipment housings, and modular building projects, specifications and performance parameters can be discussed according to the actual installation structure. Packaging methods can also be adjusted to support volume delivery.
Quality-control personnel participate in finished-product inspection and production process management. For project-based purchasing, this helps support coordination of specification consistency, packaging, and delivery and can reduce the risk of specification mismatch between different production batches or installation areas.
