PU-sealed Rock Wool Composite Panel Sandwich Panel

Performance Features

Fire Resistance: Rock wool is non-combustible (Class A1 ), making it ideal for fire-rated wall and roof assemblies.

Thermal Insulation: Low thermal conductivity (λ ≈ 0.036–0.040 W/m·K) ensures excellent energy efficiency across all climate zones.

Acoustic Performance: The dense fiber matrix delivers outstanding sound absorption and airborne noise reduction, suitable for noise-sensitive environments.

Moisture Resistance: The PU-sealed edges provide a closed, waterproof perimeter, significantly improving durability and long-term performance in humid or outdoor conditions.

Structural Strength: Double-steel facing with concealed or tongue-and-groove interlocking joints ensures fast, clean installation with high load-bearing capacity.

Industrial Buildings Factory walls and roofing for steel-structure workshops, mechanical manufacturing plants, automotive parts facilities, electronics assembly factories, and aviation hangars where strict fire ratings are required.

Cold Chain & Warehousing Cold storage rooms, refrigerated warehouses, food processing plants requiring thermal insulation, and large-scale logistics and distribution centers.

Clean Rooms & Medical Facilities GMP-certified pharmaceutical workshops, hospital operating rooms, laboratory partitions, and semiconductor/electronics dust-free cleanrooms.

High Fire-Rating Requirements Fire compartment walls (up to 2–4 hours fire resistance), paint workshops, chemical plants with flammable/explosive materials, and data center fire-rated partitions.

Acoustic & Noise Control Recording studios, film and TV production rooms, generator rooms, compressor rooms, and noise barriers for metro stations or high-speed rail terminals.

Commercial & Public Buildings Shopping malls, convention centers, sports arenas, temporary structures, and prefabricated modular buildings.

Energy Retrofit & Green Building Exterior wall insulation upgrades for existing buildings, roof energy-saving renovations, and projects pursuing LEED or BREEAM green building certification.

In summary, PU-sealed rock wool composite panels are the preferred choice for any construction scenario demanding a combination of fire protection, thermal insulation, and acoustic performance - making them one of the most versatile and reliable building envelope solutions available today.
