Product Description
A-Class Rock Wool Sheets for Industrial Equipment Heat Retention
Rock wool boards provide exceptional thermal insulation for industrial equipment with superior high-temperature resistance, fireproofing, and chemical stability. These sheets effectively reduce heat loss, maintain stable process temperatures, and enhance production safety across various industrial applications.
Key Applications
High-Temperature Equipment (300°C-800°C): Furnace walls, boiler tops, resistance/induction furnaces, hot blast stoves, and heat-conducting oil furnace insulation
Maintains thermal stability in 800°C environments (recommended 100-150mm thickness)
Prevents thermal bridging with proper joint sealing techniques
Customizable shapes for valves, elbows, and complex geometries
Environmental Protection
For outdoor or humid applications, moisture-proof layers (polyethylene/aluminum foil) and waterproof covers (iron sheets, fiberglass) are recommended to maintain insulation effectiveness and prevent moisture absorption degradation.
Installation Guidelines
Fill all gaps with rock wool strips to eliminate thermal bridges
Use specialized components for irregular surfaces and joints
Match thickness to operational temperatures and insulation requirements
