EPS, Rockwool
Sheet
The outer skin you see, touch, and clean. A 24-gauge uPVC-coated galvanized steel sheet that gives the panel its smooth, sealed, easy-sanitise surface.

10mm Liner/Cladding Panel
Overlay 10mm cleanroom cladding that fixes directly onto existing walls. The fastest, lowest-cost route to a controlled-environment finish, with no structural work and zero downtime.
10mm Liner/Cladding Panel for Existing Infrastructure
The Moddulx 10mm liner panel clads directly onto existing walls or stands as a self-supported partition, turning standard spaces into clean, controlled environments without demolition. Because it carries no electrical conduits, it is a highly cost-effective alternative to the 2" wall panel.
- Cladding to existing walls, no demolition
- Also works as a self-supported partition
- Ideal for column claddings & bulkheads
- Aluminium Honeycomb core, 24g uPVC-coated GI skin
- Simpler install, no conduits to route
