LRB Mattresses

Product Description

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.
