II. Performance & Advantages

1. Flexible high‑density sound insulation with outstanding sound‑insulating effect. Made of high‑density polymer material with high toughness and good fitting performance. It effectively blocks airborne sound and structure‑borne sound, and delivers excellent low‑frequency noise reduction for walls, ceilings and floors.

2. Soft and bendable for diverse complex installations. As a flexible roll material, it can be freely cut and wrapped around pipelines, beams, columns and irregular wall surfaces. It adapts to various construction shapes with great compatibility.

3. Eco‑friendly and odor‑safe for indoor use. Formulated with eco‑friendly raw materials, free of pungent odor and harmful volatile substances. It can be safely installed in enclosed spaces such as home bedrooms, children’s rooms, homestays and hotels.

4. Moisture‑proof, mildew‑resistant and weather‑resistant. Non‑water‑absorbent, moisture‑resistant and mildew‑proof. It maintains stable long‑term performance in humid environments such as basements, damp shops and pipe shafts with low risk of aging and failure.

5. Ultra‑thin without reducing floor height to save space. The lightweight roll fits closely during installation without reducing indoor floor height or wall thickness, ideal for sound‑insulation upgrading of old houses and finished apartments.

6. Simple installation and compatible with complete sound‑insulation systems. It can be directly applied to base layers of walls, ceilings and floors. When used together with sound‑absorbing cotton, sound‑insulating panels and light‑steel keels, it greatly improves overall sound‑insulation performance.

7. Vibration damping to reduce structural vibration transmission. With excellent damping performance, it mitigates secondary noise caused by vibration of walls, floor slabs and pipelines, and solves problems of sound leakage and resonance noise.

III. Detailed Application Scenarios

Indoor Residential Scenarios

1. Household applications: Partition walls of bedrooms, walls and ceilings of home theater / KTV rooms, side walls of entrance doors, basements and children’s rooms. It blocks noise from neighbors’ conversations, TV and sound‑system sound leakage.

Commercial Entertainment Venues

2. Commercial KTV, chess‑and‑card rooms, escape rooms, recording studios and live‑streaming rooms. It prevents sound leakage between rooms and noise nuisance, complying with fire‑safety and sound‑insulation acceptance standards.

Office & Public Buildings

3. Partitions in office buildings, offices and meeting rooms. Converting open‑plan offices into private compartments and meeting‑room walls to guarantee conversation privacy; noise reduction for library and reading‑room walls.

4. Educational facilities: Partition walls for piano rooms, dance studios and classrooms to isolate musical and loud noise and avoid mutual disturbance between classrooms.

Industrial & Equipment Noise‑Reduction Scenarios

5. Equipment rooms, air‑compressor / fan‑pump rooms and central‑air‑conditioning machine rooms. Wall and ceiling cladding to block low‑frequency mechanical roaring and meet factory noise‑reduction and environmental‑protection noise‑testing requirements.

6. Sound‑insulated compartments and quiet operation rooms in factories. Dividing quiet zones in workshops to isolate industrial noise generated by stamping, grinding and fans.

Transportation & Supporting Projects

7. Cladding for elevator shafts and pipe shafts. Reducing resident‑directed noise from elevator operation and water‑supply‑and‑drainage pipeline vibration; sound‑insulation wrapping for outer surfaces of ventilation ducts.

Cultural‑Tourism & Other Scenarios

8. Partition walls for hotel guest rooms and homestays to reduce inter‑room noise and improve accommodation experience; sound‑insulated walls for hospital wards.

Note: Sound‑Insulating Felt is a primary auxiliary sound‑insulation material. For better noise‑reduction results, installation as part of a complete sound‑insulation wall system is recommended.
