Recently, Airkey has built a cleanroom for a customer in Liechtenstein. The cleanroom has dimension 6000mm X 4000mm X 2600mm, with the ISO Class 6 cleanliness, made of Airkey’s special aluminium frames and ceilings grids as well as transparent acrylic glass wall panels.
This modular cleanroom stands out because it realises seamless transition everywhere. First of all, the cleanroom has coving transitions both inside and outside of the cleanroom. The covings are vital in cleanroom construction and here’s how they function in cleanrooms:
Eliminate hard-to-clean corners
Covings create a smooth, curved transition between the floor and walls, walls and walls, walls and ceilings, preventing sharp 90° angles where dust, microbes, or particles could accumulate. This makes cleaning and disinfection more effective, reducing contamination risks.
Prevent particle traps
Without covings, dirt and microbes can gather in corners, increasing contamination risks in controlled environments like pharmaceutical labs, semiconductor facilities, or biotech cleanrooms. The curved design ensures particles are easily removed during cleaning.
Improve airflow & laminarity
Cleanrooms rely on controlled airflow (laminar or turbulent) to remove contaminants. Covings help maintain smooth air movement by reducing turbulence caused by sharp edges.
Meet regulatory compliance
Standards like ISO 14644 (Cleanroom Standards) and GMP (Good Manufacturing Practice) often require covings in classified cleanrooms to ensure hygienic conditions.
Another standout feature of this modular cleanroom lies in the design where the base frames are 2mm short both inside and outside. This allows for the PVC floor rolling up to the wall and maintain flush and seamless surface. Here are its main functions.
No gaps or sharp corners: By rolling the PVC flooring up the wall, also known as seamless upturn installation (typically 100–150mm high), it creates a smooth, curved transition between the floor and wall, preventing dust, microbes, and particles from accumulating in hard-to-clean 90° angles.
Essential for ISO/GMP compliance: Required in pharmaceutical, biotech, and electronics cleanrooms to meet contamination control standards.
Seamless surface: No joints or cracks where dirt or bacteria could hide, making it easier to wipe down, disinfect, or sterilise.
Improves durability & prevents damage: the upturned PVC acts as a barrier against moisture, spills, and mechanical damage (e.g., carts, equipment impact). Unlike traditional skirting tiles, a seamless coving design prevents edges from lifting over time as well.
Seamless appearance: Provides a sleek, professional look while ensuring functionality.
Covings are a critical design feature in cleanrooms, ensuring cleanliness, compliance, and operational efficiency by eliminating contamination-prone corners and improving cleanability.
