Rock wool board is a common building and industrial material with many uses and important roles. It is made of rock fiber, so it has excellent thermal insulation, sound insulation and fire resistance, suitable for a variety of different application scenarios.
Effectively prevent fire from spreading
Low thermal conductivity and excellent thermal insulation effect
Sound absorption and noise reduction
Good water repellence and air permeability; low moisture absorption
Not easy to stretch, shrink or deform
1.sulation of industrialkilns and equipmentpipes
2.Fire protection and noise reduction of building partitions,firewalls, fire doors and elevator shafts.
3.Used for thermal insulation,fire protection and moisture proof in humid environments such as vehicles,cold storage projects, air conditioning ducts,etc.
