Selected Product Highlights

Dual-Cavity Sound-Insulating Fire-Resistant Partition Wall System

This system features a lightweight steel stud framework, with low-density, weather-resistant, special-purpose fireproof boards installed on the outer layers. The system is filled with double layers of rock wool, within which acoustic barrier boards are embedded, creating a three-board, two-cavity structure that forms a multi-tiered, high-performance sound insulation barrier. Pre-set conduits are reserved within the system to achieve separation of pipelines.

Five Key Advantages

Superior Performance: Airborne sound insulation ≥ 48dB, fire resistance ≥ 3 hours; lightweight, high strength, and strong seismic resistance.

Ultimate Efficiency: The substrate can be directly finished as a decorative surface.

System Integration: Integrated assembly, decoration, and pipeline systems.

Green & Recyclable: Boards are formaldehyde-free, emit no harmful gases, are recyclable, and environmentally friendly.

Excellent Value: Wall thickness of only 140mm, saving valuable space.

Application Scenarios

Suitable for places with high sound insulation requirements, including residential bedrooms, hotel guestrooms, hospital wards, offices, museums, cinemas and theaters, school libraries, restaurants, large shopping malls, industrial factories, and other public spaces.

Looking forward, Changle Technology will continue to uphold its mission of "green factory, innovation leadership, green products, and peace of mind with Changle." We are committed to developing more high-quality, efficient, and green low-carbon renovation products, driving development through innovation, earning trust through quality, and creating greater value for our customers.
