Cleanroom Doors & Windows

Cleanroom Doors & Windows: High-Accuracy Structural Integrity

In a controlled environment, every opening is a potential breach point. Metrolabs provides specialized Cleanroom Doors and Windows, engineered to maintain the hermetic seal of your facility while facilitating safe and efficient movement.

Our door and window systems are designed with a “Zero-Ledge” philosophy, ensuring that your structural openings remain flush with your Modular Cleanroom Panels, eliminating dust traps and supporting the rigorous hygiene standards of pharmaceutical and biotech sectors.

Cleanroom Door Systems: Engineered for Pressure Stability

A Metrolabs door is a high-performance air-management component designed to withstand constant pressure differentials and high-frequency use.

Hermetically Sealed Doors

For environments requiring absolute atmospheric control, such as BSL-3 labs or high-purity pharmaceutical suites, our Hermetically Sealed Doors provide a superior barrier. 4-Sided Sealing: Unlike standard doors, these utilize a unique track system that moves the door both inward and downward upon closing. Airtight Compression: This action compresses a high-durability silicone gasket against the frame and floor, ensuring zero air leakage even under high differential pressures.

Cleanroom Swing Doors

The workhorse of the sterile facility, our Swing Doors are engineered for high-frequency use and long-term performance. Flush Mounting: Designed to sit perfectly level with the wall surface on both sides, preventing particulate accumulation. Automatic Bottom Seals: A concealed mechanical "drop seal" activates when the door closes, protecting the room's pressure gradient without the need for a floor threshold.

Air-tight Doors

Metrolabs Air-tight Doors are fabricated from double-skinned SS 304 or SS 316L with a high-density infill for thermal and acoustic insulation. EPDM Gasketing: Features specialized non-shedding gaskets recessed into the door leaf to maintain a consistent seal. Seamless Joints: All corners are interlocked and ground smooth to provide a snag-free surface for cleanroom suits and personnel.

View Panels (Double Glazed)

Visibility is essential for safety and monitoring within the "Clean Shell." Our View Panels provide transparency without compromising sterility. Flush Integration: Double-glazed toughened safety glass is mounted flush with the door or wall surface, creating a continuous, easy-to-clean vertical plane. De-Humidified Chambers: The internal cavity is filled with desiccant to prevent condensation, ensuring clear visibility across varying temperature zones.

Interlocking Doors

To prevent the loss of pressure in airlocks and gowning areas, Metrolabs provides Interlocking Door Systems. Sequential Logic: Controlled by high-accuracy electromagnetic locks, the system ensures that both the "dirty side" and "clean side" doors can never be opened at the same time. Status Indicators: Integrated Red/Green LED displays provide clear visual cues to personnel, ensuring strict adherence to entry protocols.

Pass-through Windows

For the efficient movement of small materials, our Pass-through Windows reduce personnel traffic and minimize contamination risks. Mechanical/Electronic Interlock: Just like our doors, these windows prevent a direct air breach between rooms of different ISO classes. Zero-Ledge Design: The internal chamber features radiused (coved) corners for total "wipe-down" accessibility and sterilization.

Specialized Configurations

Metrolabs customizes every opening to match your facility’s specific Standard Operating Procedures (SOPs):

Sliding Cleanroom Doors: Ideal for areas with limited floor space or for large equipment entry zones; available in manual or automated sensor-driven versions.
Emergency Exit Doors: Features “Panic Bar” hardware integrated into the cleanroom-safe design for rapid, safe egress.
Fire-Rated Doors: Specifically engineered to provide 60 to 120 minutes of fire protection while maintaining ISO-class sterility.
Lead-Lined Systems: For radiopharmaceutical labs requiring both particulate control and radiation shielding.

The Metrolabs Advantage

We focus on the fine details of cleanroom architecture. A Metrolabs door or window is not just a barrier; it is an engineered solution for high-accuracy performance.

VHP Compatibility: All finishes and gaskets are tested to withstand intense Vaporized Hydrogen Peroxide sterilization cycles without degrading or losing their seal.
Hardware Integration: We utilize recessed handles and internal hinges to ensure there are no external protrusions where dust can settle.
Audit-Ready Quality: Every unit is factory-tested for air-leakage rates, ensuring your facility is ready for GMP and ISO validation.

Technical Insight: To maintain the correct pressure gradient, we recommend using Swing Doors that open into the higher-pressure room. This allows the room’s internal air pressure to assist in holding the door firmly against the seals, further enhancing the hermetic integrity of your sterile zone.
