mineral wool board

Introduction to Mineral Wool Board

Mineral wool board, also known as rock wool board or slag wool board, is a high-performance insulation material manufactured from natural rocks (such as basalt, diabase) or industrial slag. The raw materials are melted at temperatures exceeding 1,500°C and then spun into fibers, which are subsequently bonded with a thermosetting resin and compressed into rigid boards. This product is widely recognized for its exceptional thermal insulation, fire resistance, sound absorption, and water repellency. It is a staple material in the construction, industrial, and HVAC sectors, serving as a critical component for energy efficiency and safety in modern buildings. The global market for mineral wool board has seen steady growth, driven by increasing regulations on building energy codes and fire safety standards.
