Application and other Characteristics
Rockwool Slabs are used for both hot and cold insulation to conserve energy. Lower density materials are used for building applications like underdeck insulation, wall insulation and sound proofing of partitions and over false ceilings, airconditioning duct insulation & chimney insulation. Higher density materials are used for high temperature application like furnaces, ovens, autoclaves, kilns etc.
Maximum Service Temperature : 750°C
Thermal Conductivity :
Thermal Conductivity varies with the temperature and density of insulation as shown in the fig.
Thermal conductivity (W/M.K) X Mean Temperature (°C)
Sound Absorption :
Rockwool Slabs 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.
Fire Resistance :
Rockwool Slabs are incombustible and resist the spread of flame. They can withstand fire exposure temperatures and hence can be used for fire proofing.
Compression Resistance :
Rockwool Slabs are highly resilient and easily regain their nominal thickness after the removal of normal compressive load.
Moisture Resistance :
Rockwool Slabs are moisture resistant. Should the slabs become wet, full thermal efficiency will be restored after drying out the moisture.
Corrosion Resistance :
Rockwool Slabs will not cause, initiate or promote corrosion.
