Rockwool ( former CSR / Roxul ) Rockwool Insulation



Rockwool has served as the most economical & light-weight material in industrial & commercial insulation throughout the years. We provide a wide range of mineral wool and associated products (operating temperature range from –268 up to 820 degree Celsius). These products offer outstanding thermal, acoustic, fire-protection and personnel protection properties. Rockwool is a versatile material for most insulation applications.


Rockwool is generally used in the following applications:

Process temperature control, energy conservation, condensation prevention for plant and equipment such as storage tanks, heat exchangers, reactors, precipitators, stacks, ovens, air-conditioning ductwork and refrigeration equipment, as well as large diameter piping.

Personnel protection for plant equipment such as exhaust flues, hot gas ducts, boilers, furnaces, autoclaves and kilns in power generating, metallurgical, oil refining, and chemical industries.

Lining metal decks/roofs and wall sheeting, as filler for cavity walls and partitions acting as resilient load-bearing medium required for vibration isolation in walls, floors and other structural elements.
