Application and other Characteristics
Rockwool Mattresses are used for both hot and cold insulation to conserve energy, maintain process temperature, provide personnel protection, prevent condensation and reduce noise level. Rockwool mattresses are used for thermal insulation of pipes, tanks, equipments, boilers, electrostatic precipitators, flues and ventilation ducts, ovens, furnaces, kilns and fire insulation of fire doors.
Standard SizeMaximum Service Temperature : 750°C
Thermal Conductivity :
Rockwool products have extremely low K-Values for wide range of temperatures. Typical thermal conductivity values are given in the graph for various densities and mean temperatures. Conductivity varies with the temperature and density of insulation.

Sound Absorption :
Rockwool Mattresses provide excellent acoustical absorption and noise reduction co-efficient. Due to high noise reduction co-efficient, they are used in acoustic insulation work for Gensets, auditorium, theatres, public places and industrial areas where noise reduction is required.
Compression Resistance :
Rockwool mattresses offer high resistance to compression. It regain their nominal thickness after removal of a normal compressive load.
Moisture Resistance :
Rockwool Mattresses are water repellant and do not absorb moisture by capillary action or abmient moisture from the atmosphere. Should blankets become wet, full thermal efficiency will be restored on drying out.
Corrosion Resistance :
Will not cause, initiate or promote corrosion.
Flexibility :
Rockwool 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 mesh prevents any cracking or breaking.
Fire Resistance :
Rockwool Mattresses are incombustible and resist spread of flames.
