Rock Wool Panels used for Harbin Tianjiu Lanwan Villa Construction

Core Advantages and Performance Highlights

1. Targeted thermal insulation: The fibers of oriented rock wool panels are arranged in a directional manner, with a low thermal conductivity (usually ≤0.040W/(m·K)). A thickness of 120mm can meet the energy-saving requirements of Harbin's severe cold region, significantly reducing heat transfer between indoor and outdoor spaces. It cuts down on heating energy consumption in winter and blocks external high temperatures in summer.
2. Outstanding fire resistance: Classified as a non-combustible Class A material, it does not release toxic gases when exposed to fire. It can form an effective fire barrier, preventing the spread of fire along the external wall, enhancing the overall fire safety level of the villa, and meeting the high safety requirements of high-end residences.
3. Excellent bonding and structural stability: It has high bonding strength with base coat mortar (≥0.15MPa). When fixed with anchor bolts, it exhibits superior wind load resistance and crack resistance, capable of withstanding strong winds and low-temperature freeze-thaw cycles in Harbin's winter, avoiding detachment and cracking of the insulation layer.
4. Lightweight and environmentally friendly: With a low overall bulk density (usually 120-160kg/m³), it does not increase the load on the external wall, enabling convenient and efficient construction. The material itself does not release harmful substances such as formaldehyde, complying with green building environmental standards and ensuring residential health.
5. Dual functions of moisture resistance and sound insulation: It has a water repellency rate of ≥98%, effectively blocking outdoor moisture from infiltrating the wall and avoiding wall dampness and condensation in winter. Meanwhile, it possesses excellent sound insulation performance, reducing the transmission of outdoor noise into the room and improving residential tranquility.
