JFEロックファイバー Company Profile

Contributing to society through product development that directly responds to the needs of families.

Our company was established in 1989, with Kawasaki Steel (now JFE Steel) and Matsushita Electric Works (now Panasonic) as the main shareholders, for the purpose of manufacturing and selling raw materials and processed products of inorganic fiber rock wool using blast furnace molten slag. Rock wool significantly contributes to energy conservation and the improvement of fire resistance and insulation performance due to its excellent heat resistance and insulation properties. Additionally, our manufacturing process reuses blast furnace slag, a byproduct of steelmaking, at high temperatures, producing products with only half the energy of conventional processes. Guided by the corporate philosophy of the JFE Group, which is "We will always contribute to society with the world's best technology," we practice the principles of challenge, flexibility, and integrity, and strive to provide products that meet our customers' needs.
