Product Details
Rock wool sandwich roof panel is a core cladding material specifically designed for modern industrial and commercial building roofing systems. Utilizing a “sandwich” composite structure, it consists of high-strength galvanized steel sheets as the top and bottom layers, filled with high-quality basalt rock wool in the middle. This is achieved through a continuous molding process, forming a high-performance roofing solution integrating structural, thermal insulation, fireproofing, and waterproofing functions.
The core value of rock wool roof panels lies in providing excellent fire safety (Class A non-combustible material) and high energy efficiency while achieving outstanding reliability. The panels possess excellent bending stiffness, capable of withstanding construction, maintenance, and snow loads. The high-density rock wool core material is water-repellent and moisture-proof, ensuring stable long-term thermal insulation performance. The unique concealed connection system not only boasts a clean appearance but also effectively prevents rainwater leakage, achieving a completely airtight roof cover.
With its factory prefabrication and rapid on-site installation capabilities, rock wool sandwich roof panel significantly shorten construction time, making them an ideal choice for large-span buildings such as logistics warehouses, production plants, and cold chain facilities that prioritize safety, energy efficiency, and construction effectiveness.
