Cleanroom Sandwich Panels
Modular cleanroom wall & ceiling panels, built to spec
Every Moddulx panel combines two components: a face (the surface finish) and a core (the construction), manufactured in your chosen size. Choose from 7 surface finishes and 3 core types (aluminium honeycomb, EPS insulated, Rockwool fire-rated), available as sandwich panels in 50mm and 25mm, or a 10mm liner/cladding panel. Direct manufacturer, ISO 14644 and GMP compliant, shipped across the US and Canada.

Build your panel: sheet & core
Every Moddulx sandwich panel is built from two layers. See each one below, then choose the options that match your environment.

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
