Product Specifications:
Brand: Huangshi Craftsman
Product Name: Pipe Sound Insulation Cotton & Damping Sheet (Dual Combination)
Core Features:
Dual-layer sound insulation: High-density sound insulation cotton blocks water flow noise; golden honeycomb damping sheet reduces pipe wall vibration noise.
Six core advantages: vibration damping and noise reduction, waterproof and moisture-proof, thermal insulation and frost resistance, strong adhesion, high density and thickness, easy installation.
Five-layer craftsmanship: high-density thickened sound insulation cotton combined with premium damping sheet, strong adhesive butyl rubber, wear-resistant backing, composite aluminum foil layers (3,5,2 layers), golden honeycomb aluminum sheet, and high-density rubber-plastic cotton.
360° soft fit protection for various drainage pipes, durable and long-lasting noise reduction.
Noise reduction effectiveness: reduces noise by over 70%, lowers noise levels from up to 80-120dB down to approximately 36dB (data from Huangshi laboratory; actual results may vary by material and environment).
Suitable for kitchen, balcony, bathroom drainage pipes to significantly improve living comfort by reducing continuous indoor noise.
Materials:
High-density thickened rubber-plastic cotton with embossed aluminum foil (scratch-resistant, waterproof, moisture-proof).
High polymer sound insulation damping sheet: golden honeycomb aluminum sheet + rubber composite.
Composite aluminum foil layers with honeycomb structure for enhanced vibration damping.

Installation Notes:
Honeycomb aluminum sheets have sharp edges; wear gloves and take protective measures.
Overlap joints by 2-3 cm for better sound insulation.
Damping sheets must be tightly pressed and firmly adhered to pipes to reduce resonance noise.
Special 110 model kits available for elbows and tees with pre-cut damping sheets and insulation cotton for precise and easy installation.
Applications:
Ideal for reducing noise from indoor drainage pipes in residential buildings, especially where developers have not provided soundproofing.
Enhances sleep quality, study environment, and overall living comfort by effectively blocking water flow and vibration noise.
Additional Information:
Product quality and performance are visible and verifiable; Huangshi damping sheets outperform ordinary aluminum foil damping sheets.
Selecting the correct model requires measuring pipe circumference or providing pipe photos.
Suitable for pipe diameters commonly used in residential plumbing systems.
