(1)Ultimate Fire Safety
The handmade clean room sandwich panel achieves a maximum fire resistance limit of 240 minutes, specially designed for critical scenarios. Customized thickness options are provided for different risk areas, perfectly matching the fire protection needs of medical clean rooms, precision instrument workshops and other high-standard clean projects.

(2) Super Strong Environmental Purification
Fireproof, mildew proof and the first choice for medical clean rooms. The surface of the clean room sandwich panel is smooth and flat, not easy to accumulate dust, with superior mildew and antibacterial performance. Made of inorganic fibers from natural basalt, it is 100% non-toxic, odorless and non-radioactive, fully meeting the strict purification requirements of clean room laboratories and pharmaceutical clean rooms.

(3) Efficient Thermal Insulation and Noise Reduction
Energy-saving, noise-reducing and essential for green buildings. The handmade clean room sandwich panel has a low thermal conductivity, which can effectively block heat transfer, help enterprises achieve green energy conservation and emission reduction. It also has significant sound insulation effect, effectively reducing environmental noise and creating a quiet and comfortable working environment for clean rooms and industrial workshops.

(4) Lightweight and High Strength
Compression and bending resistant with a long service life. As a high-quality clean room wall panel and ceiling material, it is lightweight and durable, easy to construct; the lightweight design makes transportation convenient and assembly easy, significantly shortening the construction period and reducing labor input.

(5) Environmental Protection and Recyclability
Green materials, caring for the earth. Made of natural basalt through high-temperature melting, the core material of the clean room sandwich panel is natural and inorganic, with stable composition, non-toxic, odorless and no release of harmful gases such as formaldehyde. In line with the concept of modern sustainable development, it can be recycled after use, reducing environmental burden for your clean engineering projects.

Q1: Which cleanliness level scenarios are handmade clean room sandwich panels suitable for?

A: This product can flexibly adapt to various high-cleanliness level scenarios, covering the medical field (workshops related to medical devices, chemical pharmaceuticals, vaccines, dietary supplements, and nuclear medicine), the food field (baking workshops, meat cutting workshops, prepared dish workshops, food additive workshops, and pet food production workshops), as well as precision manufacturing workshops, data centers, aerospace laboratories, hospital pharmacy intravenous admixture services (PIVAS), operating rooms, electronic product workshops, clean room laboratories, medical clean rooms, electronic clean rooms, etc. Different core material combinations can meet different cleanliness level requirements, and it is fully compatible with various clean engineering standards.

Q2: Does the product support non-standard size customization?

A: Yes! We are a professional cleanroom manufacturer. Relying on elaborate manual compounding technology, we can flexibly customize non-standard thickness and width according to your project size requirements, perfectly fitting on-site installation needs without additional cutting, thus improving installation efficiency.

Q3: What is the service life of handmade clean room sandwich panels? How about their durability and weather resistance?

A: The product has excellent durability and weather resistance, with corrosion resistance, anti-aging, and moisture resistance, suitable for long-term stable use in different indoor and outdoor environments. Under normal usage conditions, the service life can reach 15-20 years with extremely low maintenance costs, eliminating the need for frequent replacement. Meanwhile, high-quality core materials enhance energy efficiency, helping clean engineering projects achieve energy conservation and emission reduction.

Q4: What is the fire resistance grade of the product? Are there any special requirements for rock wool core materials?

A: The overall product can reach Grade A fire resistance standard. Among them, the rock wool core material has a Grade A1 non-combustible rating, which is non-combustible, non-toxic, and smokeless, effectively ensuring the fire safety of clean engineering projects. Magnesium oxide series, magnesium oxysulfide boards, and other core materials can also meet Grade A fire resistance standards, suitable for various scenarios with high fire protection requirements.

Q5: Is the installation difficult? Is a professional construction team required?

A: The product is lightweight and easy to assemble, with a simple installation process. A professional construction guide manual can be provided, and professional construction team support is also available to complete the installation quickly, shortening the construction period and reducing labor input.
