What are modular cleanroom panels?
Modular cleanroom panels are factory-prefabricated wall and ceiling sections engineered for ISO 14644-1 classified environments. Each panel consists of a structural core — typically aluminum honeycomb, expanded polystyrene (EPS), or rockwool — sandwiched between powder-coated steel or aluminum skins.
Panels are machined to a strict ±0.5 mm tolerance and joined mechanically on-site to form a hermetic envelope suitable for pharmaceutical, biotech, semiconductor, food, and EV battery facilities.
Unlike site-built drywall, modular panels eliminate uncontrolled air exfiltration, simplify GMP cleaning protocols, and can be uninstalled and reused when a facility expands or reconfigures. View the full Moddulx panel system range →
One wall, two outcomes.
Imagine a single cleanroom envelope cut down the middle. On one side, traditional site-built drywall. On the other, factory-machined modular panels. Same room. Same pressure cascade. Two different stories.
Every operating-cost difference between the two sides traces back to one input — manufacturing tolerance. See how we hit those tolerances in our Windsor facility →
Three panel systems. One spec sheet.
Each Moddulx panel system is engineered for a specific compliance and performance profile — structural rigidity, thermal insulation, or fire resistance. Full datasheets, thicknesses, finishes, and ISO classifications are on our products page.
Why Ra value is a dual-purpose spec.
Surface Ra (Roughness Average) measures the microscopic variations in a surface's profile. For cleanroom panels, low Ra is a dual-purpose specification: it supports GMP cleanability and reduces lighting load.
Traditional drywall — even when sanded and painted with epoxy — retains a high Ra. Microscopic peaks and valleys trap bacteria, moisture, and particulates, making strict GMP cleaning protocols difficult to validate. They also scatter light, forcing facilities to over-specify fixtures to hit required lux levels.
Moddulx panels use ultra-smooth, powder-coated steel or aluminum skins with exceptionally low Ra values. Two outcomes follow:
- Easier GMP cleaning. Smooth surfaces eliminate the micro-pits where contaminants accumulate, simplifying sterilisation and validation.
- Lower lighting energy. Specular reflection bounces light efficiently across the room, allowing facilities to hit target lux with fewer or lower-wattage fixtures.
Linear waste, or circular reuse.
Operational carbon and embodied energy are now joined as procurement criteria. The lifecycle of a building material decides both. Drywall ends in a landfill. Modular panels start a second life.
Moddulx panels are manufactured off-site at our Windsor, Ontario facility and arrive cut to exact specifications — no site debris, no extended labour, no second deliveries. When a facility expands, reconfigures, or relocates, panels are uninstalled and redeployed, drastically lowering the embodied energy of every future renovation.
See how this plays out on real projects in our case studies.
Specified across six sectors.
Different sectors prioritise different panel attributes. See the full sector breakdown — recommended cores, ISO classes, and compliance scope for each — on our industries page.
The math of going direct.
Buying directly from a panel manufacturer changes the unit economics of every cleanroom project. Four numbers, factory-direct.
Eliminate the standard distributor markup on every panel, every joint, every accessory.
In-house manufacturing — no third-party suppliers, no waiting on intermediary handling.
You speak to engineers, not resellers. Quotes, revisions, and specs come direct.
Manufactured in Windsor, ON. Shipped through Detroit, MI and Dallas, TX.
