❓ Cleanroom Sandwich Panel FAQ: 15 Answers Every Buyer Needs
❓ 1. What Is the Best Core for a Cleanroom Sandwich Panel?
There is no single "best" core — it depends on your application:
|
Application |
Best Core |
|---|---|
|
Pharma GMP / VHP |
Cleanroom sandwich panel with rockwool core (≥120 kg/m³) |
|
Cold Room |
Cleanroom sandwich panel with PIR core |
|
High-Load Wall |
Cleanroom sandwich panel with magnesium oxide core |
|
Ceiling (Wide Span) |
Cleanroom sandwich panel with aluminum honeycomb core |
❓ 2. What Skin Material Should I Choose?
|
Environment |
Recommended Skin |
|---|---|
|
VHP / Washdown |
Cleanroom sandwich panel with stainless steel |
|
Hospital / Lab |
Cleanroom sandwich panel with antimicrobial coating |
|
Dry Cleanroom |
PVDF-coated galvanized steel |
❓ 3. What Is the Standard Panel Width?
The most common cleanroom sandwich panel width is 1150mm effective (covering 1180mm). For high-load walls, use 950mm effective width.
❓ 4. How Thick Should the Skin Be?
At least 0.5mm for walls, 0.6mm for ceilings. Thinner skins chip easily and fail air-tightness tests.
❓ 5. Do I Need a Flush Joint?
Yes. A cleanroom sandwich panel with flush joint eliminates ledges where particles and bacteria accumulate. It is mandatory for GMP and food facilities.
❓ 6. How Do I Verify Fire Performance?
Request the cleanroom sandwich panel fire test certificate (e.g., EN 13501-1, GB 8624). The core must be A-grade (non-combustible) for GMP zones.
❓ 7. What Documentation Should I Request?
- Mill cert
- Coating thickness report
- Fire test certificate
- Cleanroom sandwich panel installation guide
From a cleanroom sandwich panel Foshan manufacturer, these are standard.
❓ 8. Can a Cleanroom Sandwich Panel Be Cut on Site?
Yes, but use a diamond-tipped blade, cut from the clean side, and seal the cut edge immediately. Follow the cleanroom sandwich panel installation guide for exact steps.
❓ 9. How Do I Prevent Air Leakage at the Joint?
Use a cleanroom sandwich panel with flush joint and apply PU sealant at every vertical joint. For corners, use radius profiles.
❓ 10. How Do I Handle VHP Exposure?
Specify a cleanroom sandwich panel with stainless steel skin or a cleanroom sandwich panel with antimicrobial coating. Avoid standard PVDF paint.
❓ 11. How Do I Prevent Panel Bowing?
Use a cleanroom sandwich panel with magnesium oxide core for high-load walls, and keep panel width ≤1150mm.
❓ 12. How Do I Attach Accessories (Lights, Shelves)?
Use through-bolts with sealing washers, not self-tapping screws. Self-tapping screws compromise the cleanroom sandwich panel air-tightness.
❓ 13. What Is the Difference Between Rockwool and PIR Core?

❓ 14. Can I Reuse a Cleanroom Sandwich Panel After Dismantling?
Yes, if panels are carefully removed and edges are undamaged. A cleanroom sandwich panel with flush joint is easier to reuse than standard tongue-and-groove.
❓ 15. How Do I Choose a Reliable Supplier?
- Visit the factory — check for a dedicated cleanroom sandwich panel production line
- Request samples — verify core density and skin quality
- Ask for documentation — mill certs, fire test certificates
- Check references — ask for cleanroom sandwich panel for pharmaceutical project case studies
