Manufactured through high-temperature melting of natural rocks into fibers and pressed into boards, rock wool offers exceptional compression resistance, thermal insulation, fire resistance, and weather durability for demanding applications.

Key Application Areas

Thermal Insulation for Industrial Equipment and Pipelines

Ideal for wrapping high-temperature equipment (steel plant furnaces, chemical reactors, power plant boilers)
Reduces heat loss and energy consumption while withstanding vibration and thermal expansion
Class A fire resistance prevents fire risks from high-temperature equipment

Protection for High-Rise Building Components

Used in external wall insulation systems, roof insulation, and curtain wall cavity filling
Resists weather impact and long-term load-bearing deformation
Enhances thermal performance and reduces HVAC energy consumption
Provides fire prevention and sound insulation between floors

Transportation and Special Scenario Applications

Marine use: Engine room and cabin insulation resistant to moisture and salt spray
Subway projects: Tunnel and platform wall sound insulation with vibration resistance
Food processing plants and hospital equipment rooms: Meets strict environmental safety requirements

Performance Comparison with Alternative Materials

Material	Core Performance	Main Advantages	Typical Applications
Rock Wool Board	Class A fire resistance, ≥300℃ resistance, 0.035-0.045W/(m*K) conductivity, 30-50dB sound insulation	Combined thermal/sound insulation, chemical resistance, 20+ year lifespan	Power plant pipelines, foundry walls, hazardous storage, equipment rooms
Aluminum Silicate Wool	Class A fire resistance, ≥1000℃ resistance, 0.030-0.040W/(m*K) conductivity	Ultra-high temperature performance, lightweight	Industrial kilns, blast furnace pipelines
Polyurethane Foam	Class B1 flame retardant, 0.020-0.025W/(m*K) conductivity, water resistant	Superior insulation, easy installation	Cold storage, non-high-temperature equipment
