Quick Answer
A Dhaka clean room panel supplier provides prefabricated sandwich panels engineered to meet ISO cleanroom standards for controlled environments. These panels combine insulated cores (typically PU or EPS) with smooth, non-porous steel facings that resist contamination, moisture, and microbial growth. Choosing the right supplier in Dhaka means verifying GMP compliance, material certifications, and local installation capability before signing any contract.
Key Takeaways
- Clean room panels are specialized sandwich panels with smooth, sealed surfaces designed to control particulate contamination to ISO Class 5–8 levels.
- Dhaka suppliers typically price clean room panels between BDT 1,800–4,500 per square foot depending on core material, thickness, and surface finish.
- Pharmaceutical, garment, electronics, food processing, and hospital sectors are the primary buyers of clean room panels in Bangladesh.
- PU (polyurethane) core panels outperform EPS panels for medical and pharmaceutical facilities because of superior thermal resistance and lower moisture absorption.
- GMP certification and ISO 14644 compliance documentation are non-negotiable for pharmaceutical and hospital buyers.
- Lead times for a full clean room installation in Dhaka typically run 3–8 weeks depending on project size and panel customization.
- Common installation mistakes include skipping airtight joint sealing, using the wrong panel thickness, and neglecting HVAC coordination.
- Reputable Dhaka suppliers should provide material test reports, fire rating certificates, and post-installation support.
What Exactly Are Clean Room Panels?
Clean room panels are engineered sandwich panels with a rigid insulated core bonded between two steel face sheets, specifically designed to create contamination-controlled environments. Unlike standard wall panels, they feature flush, crevice-free surfaces, anti-microbial coatings, and airtight interlocking joints that prevent particle accumulation.
Core construction breakdown:
| Component | Standard Wall Panel | Clean Room Panel |
|---|---|---|
| Face sheet | Galvanized or painted steel | Pre-painted steel, often anti-bacterial coated |
| Core material | EPS, rockwool, or PU | PU (preferred) or EPS |
| Surface finish | Ribbed or lightly textured | Flat, smooth, non-porous |
| Joint system | Open or standard tongue-and-groove | Airtight cam-lock or concealed joint |
| Certifications required | None typically | ISO 14644, GMP, fire rating |
Clean room panels are rated by ISO class — ISO Class 5 (strictest, like surgical suites) through ISO Class 8 (less critical, like general pharmaceutical packaging). The panel specification must match the target ISO class. For a deeper look at how panel thickness affects ISO compliance, see this clean room panel thickness guide for ISO class specs.
How Much Do Clean Room Panels Cost in Bangladesh?
In Bangladesh as of 2026, clean room panel pricing varies significantly based on core material, thickness, surface finish, and supplier. Estimated price ranges (based on market observations, not guaranteed quotes) are:
- EPS core clean room panels: BDT 1,800–2,500 per sq ft (installed)
- PU core clean room panels: BDT 2,800–4,000 per sq ft (installed)
- Rockwool core (fire-rated) panels: BDT 3,200–4,500 per sq ft (installed)
Factors that push costs higher:
- Anti-bacterial or anti-static surface coatings
- Thicker panels (75mm–150mm) for higher insulation or ISO Class 5–6 requirements
- Concealed joint systems for pharmaceutical-grade builds
- Custom door frames, vision panels, and pass-through hatches
- Imported raw materials (steel coil prices fluctuate with global supply)
Decision rule: If the project budget is tight and the target is ISO Class 7–8 (e.g., general food packaging), EPS-core panels can work. For ISO Class 5–6 pharmaceutical or surgical environments, PU-core panels are worth the extra cost because of their better moisture resistance and dimensional stability.

Common mistake: Choosing a supplier based on price alone without checking whether they've completed a project in your specific industry. A supplier experienced in cold rooms may not understand the airtightness requirements of a pharmaceutical clean room.
What Industries Use Clean Room Panels in Bangladesh?
Clean room panels in Bangladesh serve five primary industries, each with distinct requirements.
🏭 Pharmaceutical manufacturing — The largest buyer segment. GMP guidelines require ISO Class 5–7 environments for drug production and packaging. Panels must be smooth, chemical-resistant, and support HVAC integration.
🏥 Hospitals and surgical suites — Operating theaters, ICUs, and sterile supply rooms require ISO Class 5–6 panels with anti-microbial surfaces. See the hospital clean room panel Bangladesh guide for specification details.
🍗 Food processing — Meat, poultry, and ready-meal factories need panels that withstand high-pressure washing, humidity, and temperature cycling. Food-grade coatings and sealed joints are essential. The food processing clean room panel guide covers HACCP-relevant specifications.
👗 Garment and textile — High-value fabric production and dyeing facilities use clean rooms to prevent fiber contamination in sensitive processes.
💡 Electronics assembly — PCB manufacturing and LED assembly require ESD (electrostatic discharge) resistant panels to protect sensitive components.
How Do Clean Room Panels Compare to Standard Wall Systems?
Clean room panels outperform standard brick, drywall, or conventional sandwich panels in every contamination-control metric, but they cost more and require more careful installation.
| Criteria | Standard Wall System | Clean Room Panel System |
|---|---|---|
| Surface porosity | High (paint, plaster) | Near-zero (pre-coated steel) |
| Joint airtightness | Poor to moderate | Excellent (cam-lock or sealed) |
| Cleanability | Difficult, paint degrades | Easy, chemical-wash compatible |
| Installation speed | Slow (wet trades) | Fast (dry, modular) |
| Thermal insulation | Low to moderate | High (PU core, low U-value) |
| Upfront cost | Lower | Higher |
| Long-term maintenance | Higher (repainting, repairs) | Lower (durable, washable) |
| GMP/ISO compliance | Not achievable | Designed for compliance |
Choose clean room panels if: the facility requires ISO classification, GMP compliance, or regular chemical sanitization. Standard walls simply cannot meet these requirements regardless of how well they're finished.
Where Can You Buy Clean Room Panels in Dhaka?
Most reputable Dhaka clean room panel suppliers operate from industrial areas including Gazipur, Savar, Tejgaon, and Mirpur. Buyers can source panels through:
- Direct manufacturer purchase — Best for large projects (500 sq ft+). Allows customization and better pricing.
- Authorized distributors — Useful for smaller projects or when a specific brand is specified by a consultant.
- Online inquiry + site survey — Most established suppliers offer free site surveys before quoting.
When contacting a supplier, have these details ready:
- Target ISO class or GMP grade
- Total wall, ceiling, and floor area (sq ft)
- Required panel thickness
- Any special requirements (fire rating, anti-static, anti-microbial)
- Project timeline
For a broader view of the local supply landscape, the Dhaka sandwich panel supplier buyer's guide covers supplier evaluation criteria in detail.
Are Clean Room Panels Good for Pharmaceutical Factories?
Yes — clean room panels are the industry-standard solution for pharmaceutical manufacturing environments in Bangladesh and globally. GMP (Good Manufacturing Practice) guidelines, enforced by the Directorate General of Drug Administration (DGDA) in Bangladesh, require controlled environments that standard construction cannot provide.
Why PU-core panels are preferred for pharma:
- Closed-cell PU foam resists moisture ingress, preventing mold growth inside the panel
- Smooth pre-coated steel surfaces withstand repeated cleaning with IPA, hydrogen peroxide, and other pharmaceutical disinfectants
- Concealed joint systems eliminate particle traps
- Panels can be specified with fire ratings (typically 30–60 minutes) to meet building codes
What pharma buyers must verify from their supplier:
- Steel coil mill certificate (confirming coating type and thickness)
- PU foam density report (minimum 40 kg/m³ for pharmaceutical grade)
- Fire test certificate (if required by facility design)
- GMP project references with client contact details
- Ability to provide IQ documentation support
For hospital operating theater specifications, the hospital OT room sandwich panel guide provides detailed technical requirements.
What Makes a High-Quality Clean Room Panel?
A high-quality clean room panel from any Dhaka supplier should meet these benchmarks:
Steel face sheet:
- Minimum 0.5mm thick (0.6mm preferred for wall panels)
- PVDF or polyester coating with anti-bacterial additive
- Ra surface roughness below 0.8 µm (smooth enough for ISO Class 6+)
Core material:
- PU foam: minimum 40 kg/m³ density, zero ODP (ozone depletion potential) blowing agent
- EPS: minimum 18 kg/m³ density (for ISO Class 7–8 only)
Joint system:
- Cam-lock or concealed fastener system
- Silicone sealant applied at all joints (food-grade or pharmaceutical-grade silicone)
- No exposed fastener heads on interior surfaces
Panel thickness:
- 50mm for partition walls in ISO Class 7–8
- 75mm–100mm for exterior walls and ceilings
- 150mm for cold-room adjacent clean rooms
Edge case: In facilities where clean rooms adjoin cold storage areas, the panel between the two zones needs to handle both contamination control and significant temperature differential. A standard clean room panel may not provide enough insulation — specify a 100mm–150mm PU panel with vapor barrier treatment.
Do You Need Special Certification to Use Clean Room Panels?
The panels themselves require certifications from the manufacturer; the facility operator needs separate validation documentation. Here's how they differ:
Supplier must provide:
- ISO 9001 quality management certification (for manufacturing process)
- Fire test reports (BS 476, EN 13501, or equivalent)
- Material safety data sheets (MSDS)
- Steel and foam test certificates
Facility operator must obtain:
- ISO 14644-1 cleanroom classification (particle count testing after installation)
- GMP certification from DGDA (for pharmaceutical facilities in Bangladesh)
- HACCP certification (for food processing facilities)
- Building completion certificate from local authority
The panels enable compliance — they don't automatically grant it. Particle count testing and HVAC commissioning must happen after installation before any ISO or GMP certificate is issued.
Typical Lead Time for Clean Room Panel Installation in Dhaka
For a standard project in Dhaka, expect the following timeline:
| Phase | Duration |
|---|---|
| Site survey and quotation | 3–7 days |
| Design finalization and approval | 5–10 days |
| Panel fabrication | 10–21 days |
| Installation (per 1,000 sq ft) | 7–14 days |
| Sealant curing and finishing | 2–3 days |
| Total (typical project) | 4–8 weeks |
Larger projects (5,000+ sq ft) or those requiring imported specialty materials (anti-static coatings, specific fire-rated cores) can extend to 10–14 weeks. Plan procurement well ahead of any DGDA or GMP audit dates.
Common Mistakes When Installing Clean Room Panels
These are the errors that cause failed ISO classifications and expensive rework:
- Skipping joint sealing — Every panel joint must be sealed with pharmaceutical or food-grade silicone. Unsealed joints are particle traps and contamination pathways.
- Wrong panel thickness — Using 50mm panels where 100mm is needed creates thermal bridging and condensation inside the panel.
- Ignoring HVAC coordination — Clean room panels must be installed after HVAC duct routing is finalized. Cutting panels post-installation for duct penetrations weakens the airtight envelope.
- Using standard fasteners on interior surfaces — Exposed screw heads on interior walls collect particles and cannot be properly sanitized.
- No cove profile at floor-wall junction — Without a curved cove profile, the floor-wall corner is impossible to clean properly and will fail GMP inspection.
- Choosing a supplier without clean room experience — General sandwich panel installers may not understand the precision required for ISO-compliant joints.
For guidance on avoiding these issues during the build process, the clean room construction Bangladesh guide walks through the full construction sequence.
Which Clean Room Panel Material Is Best for Medical Facilities?
PU (polyurethane) core panels are the best choice for medical facilities, including hospitals, diagnostic labs, and pharmaceutical plants. EPS core panels are acceptable for lower-criticality environments (ISO Class 7–8 food packaging) but fall short for surgical or drug manufacturing environments.
PU vs. EPS for medical use:
| Property | PU Core | EPS Core |
|---|---|---|
| Moisture resistance | Excellent (closed-cell) | Moderate (open-cell risk) |
| Thermal performance | Better (lower U-value) | Adequate |
| Surface smoothness | Excellent | Good |
| GMP suitability | ISO Class 5–8 ✅ | ISO Class 7–8 only |
| Fire resistance | Moderate (add rockwool layer for fire rating) | Lower |
| Cost | Higher | Lower |
For rockwool-core panels where fire rating is the primary concern (e.g., corridors adjacent to operating theaters), a hybrid specification combining rockwool fire resistance with PU-coated surfaces is available from specialist Dhaka suppliers. The PU panel vs. rockwool panel comparison covers this trade-off in detail.
How to Maintain and Clean Clean Room Panels
Proper maintenance extends panel life and preserves ISO classification. A basic maintenance schedule:
Daily (during production):
- Wipe surfaces with lint-free cloths and approved disinfectant (IPA 70% or hydrogen peroxide solution)
- Check door seals and pass-through hatches for damage
Weekly:
- Inspect all silicone joints for cracking or peeling
- Clean cove profiles and floor-wall junctions with a soft brush
Quarterly:
- Full panel surface inspection for scratches, dents, or coating damage
- Re-seal any joints showing micro-cracks with compatible silicone
- Check panel fasteners for corrosion
Annually:
- Full particle count test to verify ISO classification is maintained
- Professional inspection of HVAC filter integrity and panel penetration seals
Important: Never use abrasive cleaners, steel wool, or high-alkaline detergents on clean room panel surfaces. These damage the coating and create surface roughness that traps particles, potentially causing an ISO classification failure.

FAQ
Q: What is the minimum panel thickness for a pharmaceutical clean room in Bangladesh?
A: For pharmaceutical clean rooms targeting ISO Class 6–7, a minimum of 75mm PU-core panels is recommended for walls and 100mm for ceilings. Thinner panels risk thermal bridging and condensation, which can compromise GMP compliance.
Q: Can existing brick walls be lined with clean room panels?
A: Yes. Retrofit clean room panel lining over existing brick or concrete walls is common in Bangladesh. The panels are fixed to a metal sub-frame, creating a new clean surface without full demolition. Ensure the sub-frame is properly sealed to prevent void spaces that could harbor contamination.
Q: How long do clean room panels last in Bangladesh's climate?
A: With proper maintenance, quality PU-core clean room panels last 15–25 years in Bangladesh's humid climate. The primary failure modes are joint sealant degradation (resealable) and surface coating wear in high-traffic areas.
Q: Do clean room panels require a false ceiling?
A: Most clean room designs include a false ceiling using the same panel system to create a fully enclosed, sealed environment. This is essential for ISO Class 5–7 facilities. ISO Class 8 environments may use sealed painted ceilings in some cases, but panel ceilings are always preferred.
Q: Can a Dhaka clean room panel supplier handle both supply and installation?
A: Yes. Most established suppliers in Dhaka offer turnkey supply-and-install contracts. This is preferable because it places responsibility for airtightness and joint quality with a single contractor.
Q: What fire rating should clean room panels have?
A: For pharmaceutical and hospital facilities in Bangladesh, a minimum 30-minute fire rating is typically required. High-risk areas (adjacent to electrical rooms or flammable storage) may require 60-minute rated panels using rockwool or mineral wool cores.
Q: Is GMP certification required before installing clean room panels?
A: No. GMP certification is obtained after the facility is built and validated. However, the panel specification must be designed to meet GMP requirements from the start — retrofitting non-compliant panels is expensive.
Q: What's the difference between a clean room panel and a cold room panel?
A: Cold room panels prioritize thermal insulation (typically 100mm–200mm PU core) to maintain low temperatures. Clean room panels prioritize surface smoothness, airtight joints, and contamination control. Some facilities (like pharmaceutical cold storage) need panels that satisfy both requirements simultaneously.
Q: How do I get a quote from a Dhaka clean room panel supplier?
A: Prepare a floor plan with dimensions, specify the target ISO class or GMP grade, and list any special requirements (fire rating, anti-static, anti-microbial). Most suppliers will conduct a free site survey before providing a detailed quotation.
Conclusion
Selecting the right Dhaka clean room panel supplier is one of the most consequential decisions in any pharmaceutical, hospital, or food processing facility project. The wrong choice — whether due to substandard materials, inexperienced installation, or missing certifications — can result in failed GMP audits, costly rework, and production delays.
Actionable next steps:
- Define your ISO class requirement before approaching any supplier. This determines panel specification, thickness, and surface finish.
- Request material test certificates (steel mill cert, foam density report, fire test report) from every supplier you shortlist.
- Ask for project references in your specific industry and visit completed sites if possible.
- Get at least three quotes that specify the same panel thickness, core material, and joint system — comparing quotes on different specs is meaningless.
- Coordinate with your HVAC engineer before panel installation begins to avoid post-installation penetrations.
- Budget for validation — particle count testing and GMP documentation are separate costs on top of panel supply and installation.
