Rockwool products are free from gases such as CFC, HCFC and any other Ozone Depletion material. They represent no known threat to the environment. Rock wool is classified as zero depletion potential (ODP), zero Global warming potential (GWP) and help in reducing green house effect. Rockwool slabs are semi rigid panels manufactured from stable stone fibers bonded with minimum quantity of thermosetting resin binder. They are capable of withstanding an extreme temperature up to 750⁰ C.

Rockwool is made from a special grade of rocks named as BASALT. Rock wool is called in the names of stone wool insulation, mineral wool insulation, or slag wool insulation. Rock wool has a wide range of insulation applications due to its excellent ability to block sound, thermal and fire. Rock wool is light in weight , strong , re-silent, easy to handle and cut to suit intricate shapes.

Rockwool high density slabs conforming to ASTM C 612 and Equivalent BS – 3958-5 are designed for the thermal and acoustic insulation of flat or slightly curved surfaces operating at temperatures up to 750 º C. These high density slabs are produced from long, non combustible fibers designed to bear high loads. They are easy to cut, fit and handle. The robust fibers combine high levels of thermal efficiency and acoustic absorption
