Product Description
The uniformity of fiber distribution, the diameter of fibers, the fiber lay pattern and bulk density are some special features of Rockwool slab. Rockwool resin bonded slab consists of long fine fibers spun from molten natural rocks and bonded with a thermosetting resin.Rockwool slabs have the best combination of thermal insulation, fire protection and sound absorption properties.
Product Specification
| Thickness | Density | Thermal Condyctivity | Service Temperature |
| 25 mm to 100mm. | 48,64,96,144 Kg./Cu.M | 12.5mm to 350mm Nominal Bore Outer Diameter of Pipe to be specified. | 100°Cto + 800°C |
Compression Resistance
Rockwool Slab are highly resilient and easily regain their nominal thickness after removal of normal compressive load.
Moisture Resistance
Rockwool slabs are good resistant to water Vapour, most common salts and chemicals. when tested as per IS, BS and ASTM standards the material exhibits excellent resistance to moisture absorption.
Acoustic Properties
Rockwool Slabs provide excellent acoustical and noise reduction Co-efficient, due to their high noise reduction co-efficient, they are used in acoustic insulation work for auditoria, theatres, public place and industrial areas where noise reduction is required
Corrosion Resistance
Rockwool slabs do not cause, initiate or promote any kind of corrosion
Fire Resistance
Incombustible when tested as per IS :3144 (Melting Point of fibers is above 1000 °C (1825°F))
Sound Absorption
Excellent Sound Absorption by virtue of its scientific fibre lay pattern ensuring controlled dispersion of air pockets and precise air flow resistance
Sound absorption co-efficient of Rockwool slabs 48 kg / m3 are furnished bellow :
