I. Product Specifications & Price

Drain‑Pipe Sound‑Absorbing Cotton Standard Size: 95mm*440mm, Price: RMB 8 / Sheet.
Specially designed for noise reduction of drainage pipes. It wraps around the outer wall of PVC drain‑pipes to lower noise caused by water impact. It is a dedicated material for pipe noise reduction in residential and commercial projects.

II. Performance & Advantages

1. Effective Reduction of Pipeline Water‑Flow Noise. Made of high‑density sound‑absorbing damping material. Wrapping around drain‑pipes absorbs noise generated by water hitting pipe walls and reduces transmission of drainage noise into indoor spaces.

2. Simple Installation. Dimensions fit common drainage pipes. Wrap directly onto pipes and secure with adhesive tape or cable ties. No complicated tools required, easy for on‑site residential renovation.

3. Moisture‑Proof & Corrosion‑Resistant. Non‑water‑absorbent material resists mildew and rot under humid pipe‑working conditions, maintaining stable performance over long‑term service.

4. Auxiliary Thermal Insulation & Condensation Prevention. After wrapping pipes, it reduces wall condensation caused by temperature difference, minimizes dripping issues and protects ceilings and cabinets.

5. Compatible With Complete Acoustic Construction. Widely used for drainage pipes in bathrooms and kitchens. Combined with damping sheets for further improved noise‑reduction effect. It acts as an auxiliary accessory for sound‑insulation projects.

III. Detailed Application Scenarios

Indoor Residential Scenarios

1. Home renovation: Noise‑reduction wrapping for PVC drain‑pipes in bathrooms, kitchens and balconies to reduce disturbance from upstairs drainage noise.

Commercial Entertainment Venues

2. Noise reduction for kitchen and bathroom drain‑pipes in KTV, escape rooms, live‑streaming studios and homestays to improve space tranquility.

Office & Public Buildings

3. Sound‑insulation and noise‑reduction renovation for indoor drainage pipes in office buildings, schools and hospitals.

Cultural‑Tourism & Other Scenarios

4. Mass sound‑insulation construction for drain‑pipes in high‑end decoration projects of hotels and apartments.

Note: Drain‑pipe sound‑absorbing cotton mainly reduces water‑flow noise inside pipes. For better noise‑reduction performance, it is recommended to use together with pipe damping sheets. Wall sound insulation still requires installation of dedicated wall sound‑insulation systems.
