Clean room sandwich panel

Bona is a clean room panel, door and window manufacturer in China supplying construction materials for clean room projects.


Clean rooms are closely related to manufacturing industries like electronics, pharmaceuticals, bio-engineering, medical hygiene, food, cosmetics etc. The production environment directly affects the quality of products. The pharmaceutical industry has strict requirements for workshop production environment.


Below is the construction points of wall and ceiling for a  cleanliness of 100000 grade biological pharmaceutical factory:


Dust-free workshop generally adopts  clean room sandwich panel to install the walls and ceilings.


  • Installation requirements for clean room sandwich panel walls of dust-free workshop


A. The interior wall of the dust-free workshop shall be smooth;

B. The seam of clean room sandwich panel has good air tightness;

C. The wall panel shall have good heat insulation and sound insulation performance;

D. Anti-static measures are required for wall panels in microelectronics industry and pharmaceutical industry needs to prevent microbial propagation;

E. The wall panel shall be convenient for installation and removal;

F. The wall panel shall be flexible enough to meet the needs of different surface materials and door and window structures;


  • The requirements for clean room sandwich panel ceiling:


A. The ceiling shall meet the needs of dust-free workshops with various air cleanliness levels and adapt to the installation of various air filters or filtration devices;

B. The ceiling joint shall have good air tightness;

C. Be able to meet the needs of installing high-efficiency filters, lamps, electrical wiring, etc.

D. Easy to install and remove;

E. In the microelectronics industry, vibration isolation requirements should be considered;


When construction of a pharma workshop, please kindly pay attention to : 

 All partitions in the clean area are made of sandwich panel, which are installed vertically to ensure that the walls in the clean area are flat, smooth and ash-free. The color of sandwich panel is white and light. The surface of clean room sandwich panel is non-toxic, corrosion-resistant, heat-resistant, moisture-proof, mildew-proof and not easy to peel off.


 All doors in the clean area shall be airtight, and the thickness of the door and the wall shall be consistent to ensure that the door and the wall are flat and consistent. The door frame is made of galvanized sheet or stainless steel, door lock and hinge are made of stainless-steel with sealing strips around the door. The door adopts concealed hinges, which not only ensures the air-tightness and flexibility of the door, but also ensures that the clean area is easy to clean without dust. The materials used ensure that the surface is non-toxic, corrosion-resistant, heat-resistant, moisture-proof, mildew-proof and not easy to peel off.


All ceilings in the clean area are made of clean room sandwich panel. The ceilings are dust-free, non-toxic, corrosion-resistant, heat-resistant, moisture-proof, mildew-proof, non-stripping, smooth and smooth.


The windows in the clean area are fixed with aluminum alloy frame with frost-free glass with good sealing for the clean area.


  • Joints 

All gaps that may affect the cleanliness shall be sealed with sealing silica gel, including: splicing gaps between clean room sandwich panel partitions, R wall panels, corners and all gaps of ceiling panels, gaps between sandwich panels and door frames, gaps between glass view panel and frames, etc.


How to choose a right sandwich panel type for a pharma factory ?

  • The sandwich panel can be divided into machined made type and hand-made type with many different kinds of core materials with different cost, such as rock wool board, glass fiber cotton, glass fiber, silicon, sulfur, magnesium, paper honeycomb, aluminum honeycomb, etc.

  • The thickness of the insulated panel is generally 50 mm, 75 mm, and 100 mm.

  • The metal skin thickness of the insulation panels is about 0.4-0.8 mm with different price. Color steel plate also has special requirements such as high weather resistance, fluorocarbon spraying, corrosion prevention and anti-static.
