Ultimate Guide to Cleanroom Panel Dimensions Standards, Thickness & Customization

I've seen too many cleanroom projects go over budget simply because the modular layout wasn't planned before the concrete was poured. It’s not just about buying panels; it’s about "modular coordination." If you ignore the standard sizing, you'll end up cutting panels on-site, creating dust, and throwing away money. This guide cuts through the noise to give you the practical data you need on length, width, and thickness for smart engineering.

Why 1150mm is the Industry Standard

Thickness: It's About Stiffness, Not Just Insulation

Here's the mistake people make: They choose 50mm panels for a 6-meter tall warehouse cleanroom to save money. The result? Wobbly walls that flex every time a door opens. For most general Electronics or pharma jobs (iso 7/8), 50mm is fine. It saves floor space.

However, if your ceiling height goes over 3 meters (10ft), bump it up to 75mm or 100mm. The extra stiffness prevents the wall from bowing under air pressure differentials. Our lead engineer always reminds clients that proper cleanroom panel dimensions selection—specifically thickness—is cheaper than reinforcing a wobbly wall later. We supply up to 200mm, but 50-100mm covers 95% of needs.

Length Limits: Logistics is the Bottleneck

The continuous production line can theoretically make a panel 100 meters long. But good luck getting that to your job site. In reality, your panel length is dictated by two things: the size of the shipping container and the patience of your installation crew.

For international projects, the 40-foot High Cube (40HQ) container is the hard limit. This caps your length at roughly 5 meters (38.7 feet). Even if you are local, handling panels longer than 6-8 meters increases the risk of them snapping or bowing under their own weight during lifting. For ultra-tall facilities, we almost always advise splicing panels rather than risking a single massive piece.

Tolerances: Where Quality Matters

Core Material: Weight vs. Dimension

The core material impacts more than just thermal values; it is the deciding factor in your structural limitations. Rockwool (Mineral Wool) is a high-density material (typically 100-120kg/m³). While excellent for fire resistance, its sheer weight restricts the manageable size of individual panels. Large-span Rockwool panels can be hazardous to maneuver manually and require a denser suspension grid to support the dead load.

In contrast, Aluminum Honeycomb offers an exceptional strength-to-weight ratio. This rigidity allows for wider spans with less deflection, making it the ideal candidate for walkable ceilings. With honeycomb, we can manufacture larger modules that reduce the number of joints overhead. At Deiiang™, whether you specify Rockwool, Magnesium Oxide (MGO), or PU, our engineers strictly cross-check your requested cleanroom panel dimensions against the material’s specific load-bearing limits to ensure both installation safety and long-term structural compliance.

Compare weight vs. size: Don't overload your structure (or your workers).
