About LRB Mattresses
Light Resins Bonded Mattresses (LRB)
Rockwool lightly bonded mattresses (LRB) consist of fine fibres spun 1 from selected rocks melted at a high temperature and bonded with a thermosetting resin. They are then felted in the predetermined fibre lay pattern and are baked to form preformed mattress of predetermined density and thickness with uniform fibre distribution.
Mattresses are then stitched, slit and chopped to specified dimensions. LRP has excellent stability and has no chicken feathering which pollutes the atmosphere during application. It has controlled thickness and density resulting in predictable heat losses.
Applications
LRB mattresses are used for both hot and cold insulation to conserve energy, maintain process temperature, provide personal protection, prevent condensation and reduce noise levels. LRP mattresses are used for thermal insulation of pipe, tanks, equipments, boiler, electrostatic precipitators, flues and ventilation ducts, ovens, furnaces, kilns and fire insulation of fire doors.

Thermal Conductivity: Products have extremely low K-values for wide range of temperatures. Typical thermal conductivity values for various densities and mean temperatures are given in the graph.
Compression Resistance: LRB mattresses offer high resistance to compression. LRB mattresses regain their nominal thickness after removal of a normal compressive load.
Moisture Resistance: LRB mattresses are water repellent and do not absorb moisture by capillary action or ambient moisture from the atmosphere. Should blankets become wet, full thermal efficiency will be restored after drying out the moisture.
Corrosion Resistance: LRB mattresses do not cause, initiate or promote corrosion.
Flexibility: LRB mattresses are designed for maximum flexibility. They will essentially retain their thickness while conforming to virtually any irregular shape. Retention of fibres by the wire prevents any cracking or breaking.
Fire Resistance: LRB mattresses are incombustible and resist the spread of flames.
Superior Thermal and Acoustic Insulation
LRB Mattresses provide exceptional thermal and sound insulation for industrial and commercial applications, effectively reducing energy loss and minimizing noise levels. Their high fibrous porosity and density deliver outstanding thermal conductivity (0.035-0.045 W/mK at 20C), making them perfect for critical environments such as power plants and chemical facilities.
Reliable Fire and Corrosion Resistance
Manufactured to meet IS: 8183 and ASTM C553 standards, LRB Mattresses are non-combustible and maintain structural stability up to 500C in service (melting point up to 1000C). Their non-hygroscopic, rot-proof nature, and optional stainless steel mesh facings provide exceptional corrosion resistance, ensuring long-term reliability in harsh industrial conditions.
FAQ's of LRB Mattresses:
Q: How are LRB Mattresses installed on industrial equipment and pipelines?
A: LRB Mattresses can be easily cut and wrapped around the desired surfaces such as pipelines, tanks, boilers, and ductwork. The reinforced wire mesh or aluminum foil facings provide secure attachment points, allowing the mattresses to be tied, sealed, or clamped for a snug fit, ensuring efficient insulation and mechanical durability.Q: What are the key benefits of using LRB Mattresses for insulation?
A: LRB Mattresses offer significant thermal and sound insulation, helping conserve energy and reduce operating costs. They are non-combustible, eco-friendly, resistant to moisture, and do not degrade or rot. Their excellent compressive strength and dimensional stability enable long-lasting performance across a wide temperature range.Q: When should I choose LRB Mattresses over other insulation materials?
A: Choose LRB Mattresses when you need insulation that can withstand temperatures from -20C to +500C, require excellent sound absorption (NRC > 0.85), and need resistance to fire, moisture, and corrosion. Their flexibility and customizable dimensions make them suitable for complex shapes and large industrial surfaces.Q: Where are LRB Mattresses commonly used?
A: LRB Mattresses are widely used in industrial environments such as power plants, refineries, and chemical plants. They are ideal for thermal and acoustic insulation of pipelines, tanks, boilers, ductworks, and mechanical equipment, both in large infrastructure and commercial applications.Q: What is the process of customizing the size and facing options of LRB Mattresses?
A: Manufacturers and suppliers can tailor LRB Mattresses to your required dimensions, up to 5 meters long and 1.22 meters wide. You can also select your preferred facing material-galvanized iron wire mesh, stainless steel wire mesh, or aluminum foil-based on your application and environment's corrosion resistance and durability needs.Q: How do LRB Mattresses contribute to environmental safety?
A: LRB Mattresses are asbestos-free, non-toxic, and manufactured with eco-safe materials. Their glasswool composition ensures safe handling and excellent performance without harmful health or environmental side effects, supporting sustainable industrial insulation practices.
