Rockwool insulation refers to a type of insulation that is made from actual rocks and minerals. It also goes by the names of stone wool insulation, mineral wool insulation, or slag wool insulation. A wide range of products can be made from Rockwool, due to its excellent ability to block sound and heat.Rockwool insulation is commonly used in building construction, industrial plants, and in automotive applications. 

To manufacture Rockwool, minerals and other raw materials are heated to about 2910°F (about 1600°C) in a furnace, through which a current of air or steam is blown. More advanced production techniques are based on rotating the molten rock at high speeds in a spinning wheel, in some ways resembling the way cotton candy is made. The finished product is a mass of very fine intertwined fibers, bound together with starch. Oil is also added during production to decrease the formation of dust.

The individual fibers of Rockwool Insulation are good conductors of heat on their own, but rolls and sheets of this insulation are highly efficient at blocking the transfer of heat. They are often used to prevent the spread of fire in buildings, due to their extreme high melting point. Rockwool used in insulation plays a significant in reducing the energy comsumed in both domestic and commercial sectors.

Rockwool-Mineral Wool



Service Temperatures 

Loose Mineral Wool

Loose Mineral Wool is a high temperature insulating fiber processed from natural Rocks of selected quality. Having exceptionally long fibers and superior technical properties essential to meet severe service temperatures, it can be used for insulating equipments, tanks, pipelines, ovens, furnaces, and buildings.
They are incombustible, water repellent, odorless, non-corrosive ,non-settling, fire resistant, heat resistant and sound absortive.

The Loose Mineral Wool is felted uniformly in required thickness and density. They are mostly used for insulating industrial environments, large vessels, hot and cold air ducts, heat exchangers etc.

Loose Mineral Wool offers high resistance to compression. It has a good resilience.
-50°c to 750°c
Resin Bonded Slabs

Resin bonded slab consist of long fine fibers spun from molten natural rocks, bonded with a thermosetting resin slab which provides excellent thermal insulation, fire protection and sound absorption.

Slabs are mostly used in acoustic insulation works for auditorium, theaters and industrial areas where noise reduction is required

Incombustible when tested as per IS : 3144. Melting point of fibre is above 1000 ° C (1825 ° F). Complying with BS - 476 Part 4 and ASTM E -136.

Rockwool Slabs are designed for a wide range of applications, at both high and low service temperatures. They are also suitable for thermal insulations of ducts, large vessels, cavity walls, curtain walls and sandwich panels.
-50°c to 800°c

Lightly Resin Bonded (LRB)


Rock wool lightly resin bonded mattresses (LRB) consist of fine fibers spun from a range of selected rocks melted at high temperature bonded with a thermosetting resin. They are in a machine laid fiber pattern and are baked to form mattresses of predetermined density and thickness. Mattresses are then slit and stitched to specified dimensions.

They are non-hygroscopic & non-capillary and do not absorb any moisture from the air. Moisture has no effect on the stability of the mattresses.

Non-combustible when tested in accordance with BS - 476 part - 4 and ASTM E - 136. Class1 when tested in accordance with BS - 476 part 7, (ASTM E- 84).

Mattresses donot cause, initiate or promote any kind of corrosion.They are very flexible.They will retain thickness while conforming to any irregular shape. Retention of fibres by wire mesh prevents cracking or breaking of mattresses.

They are mainly used for Hot & Cold insulation purposes to conserve energy, thermal insulation of large vessels, boilers, various equipments, ducts, flangers, valves and industrial plants operating at high temperatures.
