Automatic Hermetic & Semi-Hermetic Sliding Doors
For contractors, installers and specialist fit-out companies working within controlled environments, door systems must provide reliable sealing performance while integrating efficiently with healthcare and cleanroom construction.
Our automatic hermetic and semi-hermetic sliding door systems are engineered for environments where hygiene, pressure control and environmental separation are critical.
Designed for use in hospitals, laboratories, pharmaceutical production areas, cleanrooms and advanced manufacturing facilities, these systems combine airtight sealing, durable hygienic construction and dependable automation — making them suitable for both new installations and refurbishment projects within regulated environments.
Supplied direct to trade for clean rooms, healthcare & controlled environments, the hermetic automatic door systems provide installers with a dependable, specification-ready solution for critical area access control.
Hygienic Construction for Controlled Environments
Hermetic doors are designed to maintain environmental separation between spaces while supporting strict hygiene standards.
Door panels are manufactured with a rigid internal core finished in high-density laminate (HPL), providing a robust surface suitable for frequent cleaning and resistant to impact damage in busy clinical environments.
Key construction features include:
✔ Hygienic HPL-coated rigid door panels
✔ Tubular perimeter seals for improved air tightness and durability
✔ Rolling ramp sealing system guiding the panel tightly into the frame
✔ Smooth surfaces with no exposed fixings
✔ Dust-protected operator cover
✔ Optional vision panel glazing for room supervision
These design features help ensure the door system supports the
cleaning protocols and environmental control requirements
typical in healthcare, production and pharmaceutical facilities.
Certified Airtight Performance
Tested by independent laboratories for airtight performance in accordance with NF EN 1026:2016 Air Permeability Standard
(equivalent to BS EN 1026 and DIN EN 1026).
- Air leakage rate below 1 m³/h·m² at 20 Pa
This performance level makes the doors suitable for use in environments where pressure stability, air containment and contamination control are essential.
Typical applications include:
- Hospital operating theatres
- Clean room facilities
- Pharmaceutical production areas
- Research laboratories
- Controlled manufacturing environments
Why Choose Portal UK Automatic Hermetic Door Systems?
Automatic hermetic doors offer several performance advantages that support contractors and installers working in sterile and controlled environments:
✔ High-performance airtight seals and gaskets for operating theatres and sterile areas
✔ Reduced airborne dust and contamination transfer between spaces
✔ Improved acoustic insulation, helping create quieter environments
✔ Contactless automatic operation using sensors — ideal for sterile environments
✔ Alternative activation options including push buttons, elbow switches or foot controls
✔ HPL contamination-resistant door panels for durability and hygiene
✔ Optional X-ray radiation protection with lead-lined panels
✔ Smooth hygienic design supporting easy cleaning and maintenance
These features help contractors deliver environments that meet
clinical hygiene standards and controlled airflow requirements.
Automatic Hermetic Sliding Doors
Fully hermetic automatic sliding doors provide maximum sealing performance in critical environments where strict air containment is required.
The sliding panel design ensures:
- Precision sealing against the frame
- Reduced air leakage between spaces
- Reliable automated access for staff and equipment movement
Optional radiation-shielded panels make these systems suitable for areas requiring X-ray protection, such as imaging departments and diagnostic rooms.
Semi-Hermetic (Controlled Leakage) Doors
Semi-hermetic doors provide controlled airflow management in environments where full hermetic sealing is not required but air transfer must still be limited.
Specialised sealing systems help:
- Reduce air passage between areas
- Maintain consistent internal pressure conditions
- Limit the spread of airborne contaminants, infection or dust
These doors are commonly specified for laboratories, preparation rooms and pharmaceutical processing spaces where environmental stability is required.
