Frequently Asked Questions

LRB mattresses are used to insulate boilers, vessels, furnaces, tanks, and large pipes in industrial plants.

Yes, it is designed for high-temperature industrial systems where thermal stability is required.

LRB stone wool mattresses can typically operate at temperatures up to around 650°C, depending on specification.

Power plants, refineries, petrochemicals, cement, fertilizers, and other process industries commonly use them.

It creates a thermal barrier that limits heat escape from hot equipment and piping.

Yes, stone wool LRB mattresses are non-combustible and offer excellent fire resistance.

LRB mattresses are available in multiple densities and thicknesses to suit different temperatures and applications.

Yes, they are especially suited for boilers, vessels, tanks, and large or irregular surfaces.

Yes, stone wool also helps reduce industrial noise and vibration to some extent.

They are commonly supplied with galvanised wire mesh and optional additional facings if required.

Selection depends on operating temperature, equipment size, exposure conditions, and insulation thickness needed.

Yes, LRB mattresses comply with major Indian and international industrial insulation standards.

Driving Industrial Thermal & Fire Performance

LRB or Low Resin Bonded Mattress insulation made from stone wool is widely used in industrial environments where high temperatures, fire safety, and energy efficiency are critical. Designed for demanding operating conditions, LRB insulation mattresses help reduce heat loss, improve process stability, and protect equipment in energy-intensive process.

As a global insulation leader, Saint-Gobain sets strong benchmarks in stone wool insulation by combining reliable thermal performance with fire safety and long service life. LRB mattresses comply with key industrial standards such as IS 8183, IS 3144, and ASTM C592, ensuring consistency, safety, and regulatory compliance across industrial projects.

Why LRB Mattress Matters — Strategic Business Impact

In industrial operations, insulation performance directly affects productivity, safety, and operating costs. LRB mattress insulation delivers strong business value by improving energy efficiency, enhancing fire protection, and supporting stable operating conditions.

Industries such as power generation, petrochemicals, refineries, fertilizers, cement, and other process industries rely on LRB mattresses to maintain thermal efficiency in boilers, vessels, furnaces, and large piping systems. Reduced heat loss leads to lower fuel consumption, improved process control, and lower lifecycle costs.

Beyond supplying insulation products, Saint-Gobain supports engineering teams by recommending suitable insulation solutions that improve long-term operational reliability rather than focusing only on short-term material supply.

Maximizing Energy Efficiency and Sustainable Industrial Operations

LRB stone wool mattresses play a key role in energy conservation by limiting thermal losses from hot equipment and pipelines. Improved insulation efficiency helps industrial plants reduce energy demand, lower operating costs, and support sustainability targets.

By reducing heat loss, LRB mattress insulation contributes to lower carbon emissions over the operating life of industrial systems. Product features such as low binder content and certifications like EUCEB and GreenPro support safer handling, durability, and responsible insulation practices, aligning with enterprise-level energy and sustainability goals.

How LRB Mattress Construction Enables Thermal Stability and Durability

LRB mattresses are manufactured using high-quality stone wool fibres formed into flexible mattresses and reinforced with galvanised wire mesh or when required with steel mesh. This construction allows the insulation to maintain shape and performance even under continuous high temperatures and mechanical stress.

Low resin content supports thermal stability, while the wire mesh reinforcement helps the mattress withstand vibration, thermal cycling, and repeated maintenance removal and refitting. This makes LRB mattress insulation suitable for long-term use in industrial environments where reliability and durability are essential.
