Rockwool Wall Panel
Fire resistance: Rock wool is made of minerals such as basalt and is a Class A non-combustible material. It can effectively prevent the spread of fire and improve building safety.
Thermal insulation: Rock wool has a low thermal conductivity, which can effectively reduce heat transfer, improve building insulation effect, and reduce energy consumption.
Sound insulation: The porous structure of rock wool can absorb sound waves and reduce noise transmission, and is suitable for places where sound insulation is required.
Corrosion resistance: Rock wool has stable chemical properties, is resistant to acid and alkali corrosion, is suitable for a variety of environments, and has a long service life.
High compressive strength: Rock wool has a tight structure and good compressive resistance, and is suitable for occasions that require load-bearing.

Rockwool wall panels are advanced insulation and fire-resistant building materials widely used in residential, commercial, and industrial construction. Known for their thermal insulation, acoustic performance, and fire resistance, these panels combine rockwool (mineral wool) cores with various facings to deliver a high-performance wall cladding solution.
This article provides a detailed technical overview of rockwool wall panels, covering material composition, engineering principles, industry standards, regulatory requirements, installation best practices, and maintenance guidelines to help architects, engineers, and contractors make informed decisions.
What Are Rockwool Wall Panels?
Rockwool wall panels consist of a core made from rockwool insulation fibers, sandwiched between facing layers such as galvanized steel, aluminum, or coated steel sheets. These panels are designed to provide thermal insulation, fire protection, and sound attenuation while also serving as a durable exterior or interior cladding.
Material Composition and Engineering Principles
Core Material: Rockwool (Mineral Wool)
Composition: Made from natural basalt rock and recycled slag spun into fibrous wool.
Properties: High melting point (~1,000°C), non-combustible, low thermal conductivity (typically 0.034–0.040 W/m·K).
Density: Typically ranges from 80 to 180 kg/m³ depending on application.
Fire Performance: Classed as A1 non-combustible under EN 13501-1.
Facing Materials
Galvanized Steel: Common for exterior panels; thickness ranges from 0.4 mm to 0.7 mm.
Aluminum or Aluminum Composite: Lightweight and corrosion resistant.
Coatings: Polyester, PVDF, or PE coatings for enhanced weather resistance and aesthetic options.
Panel Construction
Core thickness varies from 30 mm to 150 mm depending on insulation requirements.
Panels typically feature tongue-and-groove or shiplap edges for secure jointing.
Panels can be manufactured in sizes up to 1200 mm width and lengths up to 12 meters.

Engineering and Installation Considerations
Design & Structural Integration
Rockwool panels can be load-bearing or non-load bearing; consult structural engineers.
Compatible with steel, concrete, or timber framing.
Ensure panel joints are sealed with fire-resistant sealants to maintain integrity.
Installation Best Practices
Handle panels with care to prevent damage to facings.
Install vapor and weather barriers as required by local codes.
Fastening using self-drilling screws with appropriate washers recommended.
Maintain panel alignment and ensure expansion gaps for thermal movement.
Verify insulation continuity at panel joints to avoid thermal bridging.
Safety Precautions
Personal protective equipment (PPE) is necessary during cutting and handling.
Avoid inhalation of dust fibers; use dust masks and ventilation.
Follow local regulations regarding disposal of cutting waste.
