About

The walls of a pharmaceutical clean room are designed to create a smooth, non-shedding, airtight, and easily cleanable surface that prevents contamination and supports a controlled environment. Unlike ordinary walls, clean room walls are built with special materials and finishes that resist chemical corrosion, microbial growth, and particle accumulation. Their design complies with GMP (Good Manufacturing Practices), ISO 14644, and EU GMP cleanroom standards.

Key Features of Clean Room Walls

1. Smooth, Flush, and Non-Shedding

   • No cracks, gaps, or joints where dust or microbes can accumulate.

   • Surfaces are seamless and flush with floors and ceilings.

2. Material of Construction

   • Sandwich Panels (most common):

     • Puff Panels (Polyurethane Foam) good insulation, lightweight.

     • Rockwool Panels fire resistant and soundproof.

     • EPS (Expanded Polystyrene) Panels economical option.

   • Stainless Steel (SS 304/316) used in critical Grade A & B sterile zones.

   • Powder-Coated Galvanized Iron (GI) Panels durable and corrosion resistant.

   • HPL (High Pressure Laminate) or PVC Sheets for non-sterile or secondary areas.

3. Chemical Resistance

   • Withstands repeated cleaning and disinfection with IPA, hydrogen peroxide, quaternary ammonium compounds, etc.

4. Airtight & Pressure Control

   • Proper sealing around joints and penetrations ensures controlled air pressure differentials.

5. Coving & Rounded Corners

   • Walls are connected with aluminum/SS coving (curved edges) at wall-to-wall, wall-to-floor, and wall-to-ceiling joints.

   • Eliminates sharp corners, making cleaning easier and preventing microbial growth.

6. Fire & Thermal Resistance

   • Rockwool and mineral wool panels provide fire resistance.

   • PU and EPS panels offer thermal insulation for controlled temperature areas.

7. Integrated Utilities

   • Walls may have flush-mounted windows, electrical sockets, service panels, and pass boxes.

   • All fittings are flush with the wall surface to maintain cleanability.

8. Easy Installation & Maintenance

   • Modular wall panels are prefabricated and easy to install or replace.

   • Maintenance is simple due to detachable panel system.
