Advantages of Handmade Rock Wool Sandwich Panels 

Class A Fire Rating: Rock wool is an inorganic, non-combustible material meeting Class A fire standards. It maintains structural integrity even under high temperatures.

Thermal Insulation: Rock wool exhibits low thermal conductivity (typically 0.035–0.045 W/m·K), effectively blocking heat transfer.

Sound Absorption: Handmade rock wool sandwich panels can significantly absorb sound, making them ideal for electronics, medical facilities, and other spaces with stringent acoustic requirements.

Green Building Structure: Rockwool contains no harmful volatile compounds such as formaldehyde or benzene, emits no odor, and does not irritate, meeting green building requirements.

Installation Methods for Handmade Rockwool Sandwich Panels

Wall Installation: Nesting or interlocking installation via aluminum profile stud structures.

Ceiling Installation: Use light steel framing and suspension rod systems to assemble rock wool panels as cleanroom ceiling panels.

Custom Assembly: Reserve openings for purification equipment, ductwork, doors, and windows to achieve high-precision structural adaptation.

During installation, critical factors such as joint sealing, edge treatment, and environmental cleanliness must be addressed to ensure system performance stability and longevity.

Common Applications

Hand-made rock wool sandwich panels serve diverse scenarios, including:

Cleanrooms and GMP Facilities: Can offer fire safety and cleanliness standards for walls in cleanrooms, pharmaceutical, and electronics manufacturing.

Industrial and Commercial Buildings: Use in roofs, walls, ceilings, and firewalls for warehouses and offices.

Residential Housing: Offering energy-efficient partitions and cladding for homes and apartments.

Special Applications: Provide sound barriers, marine insulation, and acoustic solutions for high-traffic areas.

Cowinlife Homes: Key components for prefabricated buildings, ensuring thermal insulation and fire resistance in modular houses.
