Single/Double-Sided Gypsum-Rock Wool Composite Sandwich Panel

This panel features a five-layer composite structure—comprising a color-coated steel face, a gypsum backing layer, a rock wool core, another gypsum backing layer, and a color-coated steel face—custom-fabricated using precision manual craftsmanship. The result is a multifunctional industrial cleanroom panel that combines exceptional fire resistance with structural strength.

Class A1 Fire Rating & Multiple Fire Barriers

Dual flame-retardant system (gypsum + rock wool) ensures sustained stability when exposed to fire and produces minimal toxic smoke.

High Compressive and Flexural Strength

Composite structure featuring steel facings and a gypsum core significantly enhances overall panel strength, making it suitable for partition systems with high load-bearing requirements.

High-Efficiency Sound and Thermal Insulation

Rock wool core combined with a multi-layer composite structure delivers a weighted sound insulation value of ≥ 45 dB and thermal conductivity of ≤ 0.040 W/(m·K).

Precision Custom Craftsmanship

Flat surfaces and precision-cut edges perfectly meet the rigorous standards for joint tightness and surface uniformity required in cleanrooms.

Cleanroom Compatible & Environmentally Friendly

Anti-static, corrosion-resistant, and easy-to-clean surface; eco-friendly, non-volatile materials that comply with health and hygiene standards for cleanroom environments.

Applications:

Semiconductor/LCD Cleanrooms: Partition wall and ceiling systems for Class 1,000 to Class 100,000 cleanrooms

Biopharmaceutical GMP Facilities: Sterile formulation production lines and biosafety laboratory enclosures

Precision Instrument & Optical Equipment Rooms: Enclosures for constant temperature and humidity environments; vibration-damping and sound-insulating walls

Aerospace Clean Assembly Areas: Clean assembly workshops for precision components and partitions for testing environments

Medical Device Manufacturing Workshops: Sterile production areas, laboratories, and clean packaging zones
