High-Performance Partition Systems — Engineered for Controlled Environment Integrity
Cleanroom wall and partition systems perform a fundamentally different function from standard building partitions. A standard office or industrial partition defines a space boundary — it provides visual separation and minor acoustic attenuation, but makes no claim to airtightness, thermal insulation, chemical resistance, or contamination control. A cleanroom partition system must perform all of these functions simultaneously, and maintain that performance under the mechanical, thermal, chemical, and biological demands of the cleanroom operating environment throughout the facility service life.
🔌 Why Cleanroom Partitions Are a Critical Engineering System
The cleanroom partition system is the structural shell within which the HVAC system establishes and maintains the ISO class pressure cascade. If the partition system has air leakage — at panel joints, at panel-to-ceiling junctions, at penetrations for services — the HVAC system cannot maintain the designed pressure differential between adjacent rooms. When the pressure differential cannot be maintained, contamination control relying on positive pressure (the higher-pressure clean room driving air outward through any small opening, preventing the lower-pressure room from contaminating it) fails.
This is why every Metrolabs partition system uses advanced sealing at all panel joints — pharmaceutical-grade sealant at all panel-to-panel junctions, panel-to-floor junctions, panel-to-ceiling junctions, and penetration seals at all service entry points — to create the hermetically sealed shell that the HVAC system requires to establish and maintain the ISO class.
Four Engineering Requirements Every Metrolabs Partition System Meets
Airtight Integrity — Pressure Cascade Maintenance
Every panel-to-panel joint and every panel-to-structure junction is sealed with advanced sealing technology — silicone or polyurethane sealant applied continuously with no gaps — ensuring the partition system can maintain the 10–15 Pa pressure differential required for cleanroom contamination control between adjacent zones.
Thermal Stability — Consistent ISO Class Environment
Thermal bridging through the partition system creates localised cold surfaces on the cleanroom-facing panel skin — cold surfaces cause condensation that creates moisture accumulation points for microbial growth. High-density PUF or Rockwool core panels eliminate thermal bridging by providing continuous insulation through the full panel cross-section, maintaining the panel skin temperature above the dewpoint throughout the cleanroom temperature and humidity operating range.
Chemical Resistance — Full GMP Disinfectant Range
The cleanroom-facing panel surface is the surface that is wiped down with pharmaceutical disinfectants (IPA 70%, QAC, PAA, NaOCl, VHP) at every cleaning cycle. The panel surface must maintain its non-porous, non-shedding, colour-stable finish under repeated exposure to the full GMP disinfectant range throughout the cleanroom service life without surface degradation, paint peeling, or substrate exposure.
Modularity — Future-Proof Reconfiguration Without Structural Alteration
Pharmaceutical manufacturing facilities and research laboratories change their process layouts over their service life — new manufacturing processes require different room configurations, new regulatory requirements mandate additional airlocks, and facility expansion requires adding new cleanroom areas. Metrolabs modular cleanroom panel systems can be demounted and reconfigured without cutting into the building structure — panels are removed from the cam-lock or tongue-and-groove joint system, moved, and reinstalled in the new configuration with the same airtight sealing performance as the original installation.
Four Specialised Panel Systems for Every Cleanroom Classification
A complete range of wall and partition panels tailored to the thermal, structural, fire-rating, and contamination control requirements of your specific facility:
Ideal for environments requiring strict temperature control — cold rooms, controlled temperature zones, and specialised microbiology laboratories. High-density polyurethane foam core with pre-painted GI or SS skins provides the highest thermal insulation performance in the cleanroom panel range.
- Superior Insulation: High-density PUF core provides excellent thermal resistance (Lambda ≈ 0.022 W/mK) — prevents condensation on panel skins
- Structural Rigidity: Light yet exceptionally strong — large-span partitions without additional intermediate structural support
- Vapour Tight: Closed-cell foam structure prevents moisture absorption and condensation within the panel body
- Chemical Resistant Surface: Pre-painted GI or SS 304/316L skin — withstands full pharmaceutical disinfectant range
- Airtight Joints: Advanced sealant at all panel-to-panel junctions — pharmaceutical-grade silicone or PU sealant
The industry standard for pharmaceutical and healthcare environments — available with PPGI (Pre-Painted Galvanized Iron) or Stainless Steel skins with choice of core material selected for the thermal, acoustic, and fire-rating requirements of each room in the facility.
- PPGI Skin: Pre-painted galvanized iron skin — standard pharmaceutical Grade C/D and hospital environments
- SS Skin: Stainless steel skin for maximum chemical resistance — Grade A/B environments and wet areas
- PUF Core Option: Maximum thermal insulation — cold rooms and controlled-temperature areas
- Rockwool Core Option: Fire-rated — FM-approved applications and hospital environments requiring fire compartmentation
- Honeycomb Core Option: Ultra-lightweight — maximum strength-to-weight for large-span applications
- Flush Design: All joints perfectly flush — zero external ledges where dust can settle
Designed for flexibility and future-proofing — modular systems allow for easy reconfiguration or expansion of your laboratory space without cutting into the building structure. The interlocking joint system ensures an airtight seal at every panel junction while allowing complete demountability.
- Tongue-and-Groove: Precision-engineered joint system — airtight seal achieved mechanically at installation
- Cam-Lock Mechanism: Positive mechanical lock at each joint — panels cannot pull apart under pressure differential
- Utility Integration: Internal conduits for electrical, gas, and data lines pre-engineered — smooth exterior surface maintained
- Full Demountability: Panels can be removed and reinstalled in a new configuration without structural alteration
- Compatible Systems: Integrates with all Metrolabs pass box, furniture, and equipment mounting systems
- Ceiling Grid Integration: Compatible with Metrolabs modular ceiling grid and HEPA terminal filter systems
To eliminate “dead zones” at wall-to-wall and wall-to-ceiling junctions — where particles accumulate and microbial colonisation resists standard wipe-down disinfection — Metrolabs integrates specialised coving profiles at all internal vertical and horizontal junctions throughout the cleanroom.
- Seamless Transitions: Radiused curved profile — prevents microbial buildup at wall-to-wall and wall-to-ceiling corners
- Aluminium Profile: Anodised aluminium — strong, corrosion-resistant, matching metallic panel aesthetics
- PVC Profile: White or colour-matched PVC — flexible installation, matches HPL or painted panel finishes
- WHO GMP Compliant: Corner radius meets WHO GMP and EU Annex 1 requirements for cleanroom internal junctions
- Chemical Resistant: Both aluminium anodising and PVC compound withstand full pharmaceutical disinfectant range
Each Panel System — The Engineering Behind Cleanroom Partition Performance
Understanding what makes pharmaceutical-grade partition systems different from standard industrial wall systems:
Polyurethane Foam (PUF) panels use a rigid closed-cell PUF core — manufactured by injecting and expanding liquid polyurethane between the two panel skins in a factory press — to create a panel that is simultaneously structurally rigid, thermally insulating, and vapour-tight. The closed-cell foam structure means that each foam cell is a sealed air bubble — there are no open pathways through the foam for moisture vapour to migrate from the warm humid outside environment to the cold cleanroom interior, preventing condensation within the panel body that would degrade the foam over time and create a moisture reservoir for microbial growth inside the partition system.
The high-density PUF core (typically 38–42 kg/m³) provides a thermal conductivity of approximately 0.022 W/mK — the highest thermal insulation performance of any cleanroom panel core material. For a standard 60mm PUF panel, this translates to a U-value of approximately 0.36 W/m²K — sufficient to prevent condensation on the cleanroom-facing panel skin in most Indian pharmaceutical manufacturing environments operating at +20°C/60% RH with an ambient exterior of +35°C/80% RH. For cold room applications (0°C to +8°C), thicker panels (80mm or 100mm) are specified to achieve the required U-value for the design temperature differential.
🌡️ Thermal Resistance
Lambda ≈ 0.022 W/mK. U-value ≈ 0.36 W/m²K at 60mm. Prevents condensation on inner skin.
🔌 Vapour Barrier
Closed-cell structure — zero vapour migration through panel. Maintains moisture-free interior.
⚖️ Core Density
38–42 kg/m³ high-density PUF. Light panel weight with excellent structural rigidity for large spans.
🌢 Skin Options
PPGI (standard) or SS 304/316L (pharmaceutical Grade A/B). Chemical-resistant surface finish.
Cleanroom sandwich panels are composite structural panels — two metal skins bonded to a continuous core material — that combine the structural performance of the metal skin with the insulating, fire-rating, or acoustic performance of the core. The choice of skin material and core material is made for each room in the facility based on the specific requirements of that room’s application.
The PPGI skin (pre-painted galvanized iron with a polyester or PVDF topcoat) provides a smooth, cleanable surface for pharmaceutical Grade C/D and hospital environments at a lower cost than SS skins. The SS skin (SS 304 or SS 316L) provides maximum chemical resistance for pharmaceutical Grade A/B environments, wet areas, and any room subject to frequent VHP decontamination at high concentrations. The SS skin can be brushed, mirror-polished, or embossed to match the facility’s aesthetic and contamination control requirements.
The Rockwool (mineral wool) core option provides the fire-rated performance required for FM-approved pharmaceutical facilities and hospital applications — Rockwool is non-combustible (Euroclass A1) and maintains its structural integrity above 1000°C, preventing the PUF-core panel risk of combustion gas generation in a fire event. For facilities requiring both thermal insulation and fire rating in the same panel, a composite core (Rockwool facing layers with PUF centre) is available.
🌢 PPGI Skin
Polyester or PVDF topcoat — smooth, cleanable. Grade C/D pharmaceutical, hospital, research lab standard.
⚖️ SS Skin
SS 304/316L — maximum chemical resistance. Grade A/B environments, wet areas, VHP-intensive decontamination.
🔥
Rockwool Core
Non-combustible — Euroclass A1. FM-approved fire rating. Hospital fire compartmentation requirement.
🏰 Flush Profile
All joints flush — zero external ledges. Dust-trap-free surface at every panel-to-panel junction.
Modular cleanroom panel systems are the most specification-intensive category of cleanroom partition — requiring the joint system to achieve airtight sealing performance equivalent to a permanently sealed panel system while also being fully demountable and reusable. The precision-engineered tongue-and-groove or cam-lock joint mechanisms used in Metrolabs modular systems achieve this by applying controlled mechanical compression to a continuous silicone or EPDM gasket at every joint — the mechanical compression ensures the gasket is uniformly loaded around its full perimeter at the precise compression required for airtight sealing, and the cam-lock mechanism maintains this compression permanently without requiring adhesive sealant that would prevent future demounting.
The utility integration feature — pre-engineered internal conduits for electrical cables, gas lines, and data cables — eliminates the need for surface-mounted cable tray or conduit on the cleanroom-facing panel surface. Surface-mounted conduit and cable tray are among the most significant contamination control liabilities in pharmaceutical cleanrooms — they create horizontal ledges, vertical crevices, and complex geometry at the conduit attachment points that are difficult to clean effectively and that accumulate particles, moisture, and biofilm during normal cleanroom operation. The internal conduit completely eliminates these contamination harbour points by routing all services within the panel body.
🔄 Cam-Lock Joint
Positive mechanical lock at every joint — panels cannot pull apart under pressure differential. Fully demountable.
🔌 Airtight Gasket
Silicone or EPDM gasket compressed by joint mechanism — airtight without permanent sealant.
🔋 Utility Integration
Internal conduits pre-engineered — electrical, gas, data — zero surface-mounted conduit on cleanroom face.
🔄 Full Demountability
Panels remove and reinstall without structural alteration — future-proof layout reconfiguration.
The corner coving profiles for wall-to-wall and wall-to-ceiling junctions are the vertical equivalent of the floor-to-wall coving skirting — they eliminate the right-angle vertex at every internal cleanroom corner where the cleaning cloth cannot maintain contact with both surfaces simultaneously, creating a dead zone where particles, moisture, and biofilm accumulate between cleaning cycles.
The aluminium coving profile is the standard for cleanrooms with metallic panel finishes — pre-painted GI or SS — providing a metallic profile that matches the panel aesthetic and maintaining the visual uniformity of the cleanroom perimeter. The aluminium is anodised after profiling to provide corrosion resistance and a surface hardness that withstands repeated IPA and disinfectant wipe-down cycles without surface degradation. The PVC coving profile is used in cleanrooms with HPL (High-Pressure Laminate) panel finishes or painted surfaces, where the white or colour-matched PVC blends visually with the panel surface.
♾ Anodised Aluminium
Hard-anodised finish — corrosion-resistant — matches metallic panel aesthetic — IPA/disinfectant wipe-down rated.
🔧 PVC Profile
White or colour-matched — for HPL or painted panel finishes — flexible installation — pharmaceutical-grade adhesive.
🔌 Radius Profile
R25–R50mm — WHO GMP / EU Annex 1 wall-to-wall and wall-to-ceiling radius requirements.
📌 Full Junction Coverage
Wall-to-wall and wall-to-ceiling — all internal cleanroom corners — no dead zones anywhere in the perimeter.

Custom-Built Layouts — Optimised Workflow & Sterile Performance
Every research and healthcare facility has unique spatial challenges. Metrolabs provides custom-built cleanroom layouts that optimise workflow while ensuring every element of the partition system contributes to a sterile, high-performance environment:
Complete System Integration — Floor, Wall, Ceiling as a Unified Hermetic Shell
Wall systems are designed to integrate seamlessly with Metrolabs epoxy flooring (floor-to-wall coving at the base perimeter), ceiling systems (wall-to-ceiling panel junction with integrated coving profile), and HEPA terminal filter ceiling grid — creating a unified, hermetically sealed shell that is easy to validate and maintain. The cleanroom shell qualification — the pressure decay test that verifies the airtight integrity of the partition, floor, and ceiling system as a whole — is simplified when all three systems come from the same manufacturer with the same joint sealing specification.
Modular Future-Proofing — Reconfigure Without Structural Alteration
Metrolabs modular panel systems allow facility managers to reconfigure cleanroom layouts as manufacturing processes change — adding new rooms, changing room configurations, and expanding the cleanroom area — without demolishing existing structural walls. The panels are demounted from the cam-lock or tongue-and-groove joint system, moved to the new configuration, and reinstalled with new joint sealing at the same airtight performance specification as the original installation.
Pre-Cut to Dimension — Zero Site Waste, Minimal Installation Time
Every Metrolabs cleanroom panel is manufactured pre-cut to the exact dimensions of the facility layout, with all service penetrations, door openings, and window cutouts machined at the factory. Site installation is an assembly operation — not a fabrication operation — minimising the dust, debris, and particle-generating cutting work that would contaminate an in-service cleanroom during panel replacement or expansion work.
Pan-India Installation — Expert Team Across All States
Metrolabs partition system installation teams travel to site from Chennai with all pre-cut panels, profiles, sealants, and tools. The installation team is trained in pharmaceutical GMP partition installation — including airtight joint sealing procedures, corner profile installation, penetration sealing, and the pressure decay test procedure that verifies the airtight integrity of the completed installation before handover.
