ROCKFON is a leading provider of acoustic stone wool and metal ceiling solutions and suspension systems.
With the acquisition of Chicago Metallic®, ROCKFON provides customers a complete ceiling system offering combining ROCKFON stone wool and specialty metal ceiling panels with Chicago Metallic suspension systems. ROCKFON is a subsidiary of Denmark-based ROCKWOOL International A/S, the world's largest producer of stone wool products.
For the past 25 years, the ROCKWOOL Group has been present in North America through ROXUL® Inc., the leading manufacturer of stone wool insulation products for the North American market. ROXUL has three strategically-placed manufacturing facilities: Milton, Ontario (East), Grand Forks, British Columbia (West) and Marshall County, Mississippi (South). The factories use world-class technology to produce residential products, as well as a wide array of industrial, commercial and marine stone wool insulation products.
ROCKFON acoustic ceiling tiles have performance advantages made possible by a raw material found only in ROCKFON products: stone wool. Stone wool is produced from volcanic rock, or basalt, which features unique properties that give stone wool a number of superior performance characteristics and attributes.
