Rock Wool Sandwich Panel

Rockwool (Rock Wool) Cleanroom Sandwich Panel is a premium fire-rated purification enclosure panel, the only A1 fully non-combustible wall/ceiling material for high-standard sterile clean environments. It is thermally bonded composite structure with double-sided hygienic metal skins and vertical staggered high-density hydrophobic basalt rock wool core, matched with full set aluminum purification profiles (inner/outer curved corners, T-joint connectors, skirting as shown in your technical drawing).

Exclusive hidden tongue-and-groove interlock with EPDM rubber gaskets eliminates exposed screws and sanitary dead corners, achieving fully airtight modular assembly. Mandatory for pharmaceutical GMP, FDA cGMP and hospital fire safety codes, widely used for partition walls, ceilings and fire separation barriers of sterile production zones with flammable raw materials.

Main Structure & Material Breakdown

1. Outer Metal Facer Sheet

Three customizable surface options for different working environments:

1. Standard PPGI Pre-painted Galvanized Steel

   0.4–0.6mm thickness, matte white RAL9003 antibacterial coating (antibacterial rate ≥99.9% per ISO22196), anti-fingerprint non-porous surface resistant to alcohol, hydrogen peroxide and chlorine disinfectants. Cost-effective for electronics, cosmetic and medium-grade food cleanrooms.

2. SUS304 / SUS316L Stainless Steel (Medical & Pharma Premium)

   Wire-drawing anti-corrosion surface, withstands long-term repeated heavy disinfection, required for hospital operating rooms, vaccine production lines and high-corrosion biotech labs.

3. ESD Anti-static Coated Steel (Electronics Special)

   Surface resistance 10⁶~10⁹Ω, eliminates static discharge damage to semiconductors, chips and optical components.

2. Rockwool Core (Fireproof Insulation Core)

• Raw material: Basalt mineral rock wool, vertical staggered fiber layout to maximize structural rigidity and fire resistance

• Cleanroom dedicated density: ≥120kg/m³; economical 80–100kg/m³ available for general industrial partitions

• Hydrophobic treatment: Water repellency ≥98%, anti-mold and moisture-proof, prevents fiber shedding and mildew growth in high-humidity clean zones

• Fire performance: EN13501 Class A1 non-combustible, melting point over 1000°C, no molten dripping or toxic smoke release during fire; 50mm panel achieves 60min fire resistance, 100mm reaches 120min, 150mm up to 180min

• Thermal conductivity: 0.038–0.044 W/m·K, stabilizes cleanroom constant temperature & humidity to cut HVAC energy consumption

• Sound insulation: NRC 0.85–0.95, excellent noise absorption for equipment-intensive production lines

3. Two Production Craft Types

1. Machine-Made Rockwool Panel

   Continuous automatic production line, uniform core density, flat surface, low unit cost, ideal for mass standard cleanroom wall & ceiling projects. Hidden tongue-and-groove lock with integrated EPDM sealing strip for airtight splicing.

2. Handmade Four-Side Aluminum Frame Rockwool Panel

   Reinforced aluminum frame around four edges, superior air tightness and surface flatness, customizable non-standard sizes, recommended for high-standard hospital OR and pharmaceutical Grade A/B aseptic workshops. Pre-fabricated cutouts for air showers, pass boxes, FFUs and scrub sinks to avoid dust-generating on-site cutting.

4. Matching Aluminum Purification Profile System (Compatible with your technical drawing series)

Full supporting aluminum extrusion accessories to eliminate sanitary dead corners:

• JH001A vertical insert keel, JH213/JH214 panel locking strips

• 230 integrated curved inner/outer corners, 236 T-shaped cross connectors

• JH236 wall base skirting, door frame profiles

  All internal wall joints adopt curved arc aluminum trim, zero gaps for dust & bacteria accumulation, fully passes GMP PAO air tightness validation.

5. Standard Sizing Specifications

• Effective modular width: 980mm / 1180mm

• Core thickness options: 50mm (standard wall), 75mm, 100mm, 150mm (ceiling & fire separation wall)

• Custom length: Max 9000mm for walls, max 3500mm for ceilings, pre-cut at factory to project dimensions
