Stone wool (rock wool) is made by melting volcanic rock such as basalt and converting them to fiber form. With the ability to operate at service temperatures up to 750oC, it is predominantly used in high temperature industrial applications.
High density, low binder based semi-flexible mat for high temperature applications
Pre-formed product for easy installation on pipe : plain or with factory applied facing
In certain areas of an industry, noise levels exceed the 85dB safe limit for human ear. With excellent acoustic properties, stone wool is also used in applications to provide sound isolation / absorption.
The tiny pockets of air trapped within the physical structure of the stone wool reduce airflow and heat flow. This makes stone wool a preferred choice for thermal and acoustic insulation, especially for industries.
The fibers are then converted to various products such as LRB Mattress, RB Slab, Pipe section etc. of required density and thickness. Product can be customized to various dimensions and offered with facings as per the application.
FIBERIZING / BINDER SPRAYING
The fibres are produced by projecting the melt on rotors turning at high speed. A binder is automatically atomized on the fibers. The fibers are collected are forming an homogeneous primary mat of low gram weight. This mat is transported to the pendular installation.
FOLDING AND CRIMPING
The fibers are collected on a belt and folded using a pendulum. The fibers are passed through a crimping machine to bring mechanical properties to the final product.
Basalt and agglomerates are stored in silos, weighed and mixed with coke.
The mixture is melted at high temperature in a cupola

The fibers mat, impregnated with binder, is entering into a curing oven to be stiffened. This gives to the mat its final thickness, density and consistency.
Once out of the oven, saws cut the blanket at the required width. The panels are then packed and palletized facilitating the logistics of handling, storage and loading in the transport units.
Stone Wool offers low thermal conductivity, ensuring excellent insulation performance. It helps maintain stable temperatures, reduces energy loss, and supports efficient thermal management in industrial and commercial settings.
Stone Wool is non-combustible and can withstand temperatures above 1000°C. This makes it ideal for high-temperature applications such as power plants, refineries, and process industries where fire safety and thermal stability are critical.
Its open-fiber structure provides superior sound absorption, making Stone Wool highly effective in reducing noise transmission. It enhances acoustic comfort in commercial buildings and industrial environments with high noise levels.
Stone Wool is made from natural volcanic rock and recycled content. It is fully recyclable, supports energy savings throughout its lifecycle, and aligns with circular economy principles making it a sustainable insulation choice.
Yes. Stone Wool can be engineered with anti-corrosion technologies, making it suitable for environments with high humidity or chemical exposure. It helps mitigate corrosion under insulation (CUI), especially in process industries.
Its durability, moisture resistance, and stable thermal performance reduce the need for frequent replacements or repairs. This leads to lower lifecycle costs and improved operational efficiency for industrial facilities.
Stone Wool helps maintain surface temperatures above dew point, preventing condensation on ducts and pipes. This protects systems from moisture-related damage and supports hygienic, efficient HVAC operation.
Stone Wool maintains its structural integrity and insulation performance even under repeated heating and cooling cycles. It is ideal for applications with fluctuating temperatures, such as furnaces and process equipment.
