I. The Role and Importance of Pipe Sound Insulation Cotton

Pipe sound insulation cotton is a material specifically designed to reduce noise from sewer pipes. It is typically made of polyester fiber, glass fiber, damping materials, or composite materials, and works by wrapping the pipes to absorb sound waves and reduce vibration transmission. Its main functions include:

1. Reduce water flow noise: Pipe sound insulation cotton absorbs the noise generated by water flow impact through high-density fibers or damping coating, effectively reducing the "whooshing" sound.

2. Reduces pipe vibration: Pipe vibration is a major cause of noise transmission. The elastic structure of sound insulation cotton can buffer vibration and reduce noise transmission.
3. Improves living comfort: Especially in high-rise residential buildings or older communities, pipe noise is particularly noticeable. Sound insulation cotton can significantly improve the living experience.
4. Environmental protection and safety: High-quality sound insulation cotton uses environmentally friendly materials, meeting E0 or higher environmental standards, making it suitable for home use.
