Product Description
The CNEWRW50140DM Double-sided Mortar Composite rock wool mineral wool Board is a customized building insulation panel tailored for high-standard building exterior wall thermal insulation and fireproof systems. The core layer is made of premium natural basalt and other volcanic rock raw materials, processed through high-temperature melting, centrifugal wire drawing and curing forming technology, featuring stable physical and chemical properties, non-combustibility, no toxic smoke release at high temperature, and durable structural stability.
Different from conventional rock wool products, this product is composited with high-strength anti-cracking cement mortar layers on both sides through a special integrated bonding process. The compact mortar protective layer effectively enhances the overall surface hardness, impact resistance and weather resistance of the rock wool board, completely avoids fiber falling and layer separation during transportation and construction, and solves the problems of poor flatness and easy water absorption of ordinary rock wool boards. The optimized composite structure enables the board to be directly installed on construction base surfaces without on-site plastering treatment, greatly reducing manual construction procedures, lowering construction costs, and improving project efficiency by more than 70% compared with traditional processes.
In terms of core performance, the product achieves A1-class fireproof rating, the highest fire safety level for building insulation materials, which can effectively block flame spread and resist high-temperature baking, providing reliable fire barrier protection for buildings. It owns excellent thermal insulation performance with low thermal conductivity, which significantly reduces building heat transfer, lowers indoor temperature fluctuation, and cuts down air conditioning and heating energy consumption to realize building energy conservation. Meanwhile, the porous fiber structure of the rock wool core endows the product with outstanding sound absorption and noise reduction effects, which can effectively weaken outdoor noise transmission and improve indoor acoustic environment.
Additionally, the product features superior hydrophobic and moisture-proof performance with a high water repellent rate, preventing moisture penetration and mildew growth in humid environments, and maintaining stable thermal insulation and mechanical properties for a long time. It is resistant to aging, freeze-thaw and external environmental erosion, with a long service life matching the service cycle of building structures. Lightweight in overall weight, it will not cause extra load on the building wall, and boasts strong adaptability, suitable for new building exterior wall insulation, old building energy-saving renovation, roof insulation, partition wall fire insulation and other scenarios, being a multifunctional and high-efficiency green building insulation material.
Key Features & Benefits
Enhanced Fire Safety: As a non-combustible stone wool core (Melting point >1000°C), it effectively prevents fire spread and does not produce toxic smoke, meeting strict building safety codes .
Dual-Sided Reinforcement: The double-sided mortar coating optimizes the interface bonding with metal sheets and prevents resin migration during the panel lamination process.
Acoustic Performance: The open fiber structure provides excellent sound absorption, reducing noise transmission through facades and roofs .
Dimensional Stability: Resistant to thermal shrinkage and does not deform under high temperatures, maintaining the flatness of the sandwich panel.
Packaging & Storage
Storage: Keep dry and covered. Stacking height should not exceed 2.5 meters to prevent deformation
Applications
Core material for Metal-faced Sandwich Panels (Walls & Roofs).
Industrial Buildings (Warehouses, Factories).
Cleanrooms (Due to particle retention and chemical neutrality).
Cold storage secondary insulation (due to low thermal conductivity).
