Aluminium Profile for Sandwich Panel Installation
1. Excellent fireproof performance: The panel is produced using special raw materials, production processes and advanced machinery, giving it its outstanding fire resistant performance. Tests have determined it is resistant to temperatures of more than 1000 °C.
2. Good thermal insulation: Thermal conductivity of rock wool is 0.043W/ m·K.
3. Sound insulation: Rock wool sandwich panels have a significant effect on the reduction of noise transmission, especially in places at or near airports or other areas where planes are a common occurrence. In addition, they can reduce the sound and impact of rain and hail.
Our company can provide custom sandwich panels, with examples as follows:
Mineral wool sandwich panel also known as structural insulated panel, as both sides of the sandwich panel are made of galvanized steel sheets with a mineral wool foam core. The insulated sandwich panels listed above are some of the examples we have made, and if you have specific needs about rock wool panel size, please tell us your demands, and we can provide custom wall and roof panel solutions for you.
