Rockwool Cleanroom Panel
Rockwool is the most commonly adopted as the infill of cleanroom panels. It is made of mineral rock with a super high ignition point and excellent fire resistance. The rockwool does not shrink or deform when it is burned without producing toxic smoke. Meanwhile, it has excellent thermal insulation performance, dimensional stability and aging resistance, and effectively limits the transfer of heat.
Rockwool is with superior sound absorption characteristic, the unique fiber structure is tighter than traditional insulation materials, effectively reducing airflow and sound transmission.

Meanwhile, rockwool has stronger thermal insulation, heat insulation and noise reduction capabilities. The core material of rockwool & MGO cleanroom panels is composed of rockwool and single or double layer of MGO sheet. It combines the advantages of both MGO and rockwool, greatly improving the bending strength of cleanroom panels. It is mainly used as cleanroom walkable ceilings and is widely used in pharmaceuticals, electronics, laboratories, food factories and other applications.

What Are Cleanroom Panels?
Cleanroom panels are types of modular building panels specifically engineered for high-standard clean environments. It is constructed by metal or laminated surfaces with various insulated materials—such as rockwool, aluminum honeycomb, polyurethane or magnesium oxide—to achieve a smooth, non-dust accumulating, chemically resistant, and airtight structure. These panels are designed to maintain stable pressure differentials and meet stringent cleanliness classifications.
They are widely used in critical sectors including pharmaceuticals, hospital, medical devices, electronics & semiconductors, and food manufacturing factory and laboratories, where they serve as essential components in the construction of cleanrooms and laboratories to ensure regulatory compliance and production safety.

How Many Types of Cleanroom Panels Are There by Structure?
Cleanroom panels can be divided into two main types based on their structure: Handmade Cleanroom Panels and Machine Made Cleanroom Panels. Below, KINROM outlines the key differences between them.
1. Handmade Cleanroom Panels
Production Process:
KINROM’s handmade panels are manufactured using a fully automated production line. The process is as follows:
Steel sheet decoiling → Steel sheet bending → Assembly of galvanized steel frame and corner → Automatic glue spraying → Insulation filling (e.g., rock wool, magnesium oxide, aluminum honeycomb) → Hot/cold pressing → Stacking → Packaging.
The production cycle is relatively complex and time-consuming.
Video 1 Handmade Cleanroom Panel Manufacturing Process
Structural Features:
Reinforced with metal frames on all sides, these panels offer significantly higher compressive strength (4-5 times greater than machine made cleanroom panels) and provide superior protection to the insulation against moisture and impact, thereby extending service life. They support multi-material insulation compositions (e.g., rock wool + magnesium oxide) and achieve Class A fire resistance along with improved acoustic insulation (≥35 dB).
Picture 2 Handmade Cleanroom Panels Structure
Performance Metrics:
Excellent airtightness, suitable for Class 100 and higher cleanroom environments; surface flatness tolerance within 0.3 mm; sealed joints ensure long-term reliability and environmental stability.
Applications:
Ideal for high-standard settings such as hospital operating rooms, biosafety laboratories, and Class 100 electronic cleanrooms; also suitable for load-bearing ceilings/walls and custom projects requiring special shapes or extra-long panels.
Installation Characteristics:
Available in standard widths (1180/980 mm) and customizable non-standard sizes, significantly reducing on-site cutting and simplifying installation.
Cost and Customization:
Due to premium materials, complex processes, and high customizability (size, insulation, and surface options), these panels are generally 20-50% more expensive than machine made panels.
2. Machine Made Cleanroom Panels
Production Process:
Steel sheet uncoiling → Steel sheet bending → Glue spraying → Hot pressing → Fixed-length cutting → Stacking → Packaging.
This process is simpler and allows higher production efficiency with strong standardization.
Video 2 Machine Made Cleanroom Panel Manufacturing Process
Structural Features:
Equipped with metal edges on both longer sides, these panels have relatively lower compressive and impact resistance. They typically use a single core material (e.g., rock wool or silica rock) and are generally limited to a maximum length of 6 meters.
Picture 3 Machine Made Cleanroom Panels Structure
Performance Metrics:
Joints may be prone to leakage over time due to stress or aging; flatness tolerance within 0.5 mm; sound insulation approx. ≥30 db.
Applications:
Suited for general clean environments such as food and pharmaceutical packaging areas, standard laboratories, storage rooms, and lightweight or temporary projects requiring quick assembly.
Installation Characteristics:
Standard panel widths (e.g., 950/1150 mm) allow flexible on-site cutting, but post-installation sealing must be performed with care.
Cost and Customization:
Produced at lower cost with high standardization; customization is limited, and widths are not customizable.

What Are The Most Common Surface Materials For Cleanroom Panels?
The selection of surface material for cleanroom panels directly impacts their corrosion resistance, cleanability, service life, and compliance with cleanliness standards. Below are the most common types of surface materials for cleanroom panels. KINROM will provide a detailed introduction to their features and applications:
Pre-painted Galvanized Iron (PPGI)
PPGI is made from galvanized steel substrate coated with multiple layers of organic coatings (such as polyester PE or fluorocarbon PVDF) through a rolling process, resulting in a colorful and smooth surface. It offers rust resistance, general corrosion protection, and retains the strength of steel while providing an attractive appearance. The substrate thickness typically ranges from 0.4mm to 0.6mm, with a coating thickness of approximately 0.18–0.22μm. Due to its cost-effectiveness, good processability, and variety of color options, PPGI is widely used in general clean environments such as electronics and manufacturing.
Powder Coated Galvanized Iron (PCGI)
PCGI also uses a galvanized steel substrate but employs an electrostatic powder coating process, which delivers a thicker, more robust coating with enhanced adhesion. It offers significantly better corrosion resistance, scratch resistance, and weather ability compared to PPGI. The substrate generally ranges from 0.5mm to 0.8mm in thickness, and custom colors are available with low minimum order quantities. PCGI is ideal for high-temperature, high-humidity, or corrosive environments, including food processing plants and pharmaceutical workshops.
304 Stainless Steel
Stainless steel offers excellent mechanical strength and high resistance to chemical corrosion, high temperatures, and frequent sterilization. Common surface finishes include polished, brushed, and sandblasted. It is widely used in pharmaceutical cleanrooms, biosafety labs, operating theaters, and food processing areas where high hygiene and environmental resistance are critical.
Polyvinyl Chloride (PVC)
PVC is a polymer plastic surface material often combined with other substrates. It is fully waterproof, resistant to acids, alkalis, and common disinfectants, seamless, non-porous, and inhibits bacterial growth. This makes it particularly suitable for wet and frequently cleaned environments such as biochemical labs, hospital walls, and food and beverage processing areas.
High-Pressure Laminate (HPL)
HPL is composed of multiple layers of resin-coated specialty paper cured under high temperature and pressure. It is wear-resistant, impact-resistant, chemical-resistant, and available in a variety of decorative patterns (e.g., wood grain, solid colors, stone patterns). Standard thicknesses are 3mm and 4mm. HPL is widely used in hospital public areas, laboratory countertops, and pharmaceutical plants where aesthetics and stringent disinfection requirements are essential.
At KINROM, we supply cleanroom panels with all the above surface materials. We provide expert recommendations based on your specific operational environment, budget, and industry standards (such as GMP and ISO 14644). We also offer free samples and professional technical consultation to help you make the best choice.
