The Fireproof Soundproof PU Closing Sealing Edge Rock Wool Sandwich Panel is an advanced building material designed to provide excellent fire resistance, thermal insulation, and soundproofing properties. This type of sandwich panel is constructed with two layers of high-quality colored steel sheets, with a core material composed of rock wool and polyurethane (PU) for enhanced performance.

Key Features
Fire Resistance: The panel achieves an A1 fireproof rating, making it highly suitable for applications where fire safety is a priority.
Thermal Insulation: The combination of rock wool and PU provides superior thermal insulation, with a low thermal conductivity coefficient that ensures energy efficiency.
Soundproofing: The sandwich panel offers significant sound absorption and reduction capabilities, with a sound reduction factor of no less than 30dB.
Durability and Aesthetics: The panels are designed with a hidden-screw node and a variety of surface finishes, providing a sleek appearance and long-lasting durability.
Convenient Installation: These panels are easy to install, reducing construction time by over 40% compared to traditional methods.

Applications
The Fireproof Soundproof PU Closing Sealing Edge Rock Wool Sandwich Panel is widely used in various industrial and commercial buildings, including factory roofs and walls, storage facilities, exhibition halls, gymnasiums, purification workshops, and cold storage warehouses. It is particularly ideal for projects with high fire protection and soundproofing requirements.
