Airtight Doors provide security to a room while restricting 100% of airflow through the implementation of a tight seal. This is of particular importance if the contents of the room are potentially hazardous, for example in laboratories, server rooms, and gas or chemical storage areas. The systems we use to design these doors ensure they are manufactured to specification every time, eliminating the risk of gaps or leakage.
Every door is custom made to suit existing structural openings. They are designed on a CAD/CAM system and manufactured with CNC punching and pressing facilities to guarantee quality and long product life, so you can depend on it to secure your premises as intended.
