Cleanroom doors are a crucial part of cleanrooms and are responsible for sealing the controlled environment.
The ISO standard 14644-1 defines a cleanroom as: “a room in which the concentration of airborne particles is controlled, and which is constructed and used in a manner to minimise the introduction, generation, and retention of particles inside the room and in which other relevant parameters, e.g. temperature, humidity, and pressure, are controlled as necessary”.
The cost of air control in a cleanroom can be comparatively high. The energy requirement of HVAC systems usually amounts to 50-75% of electricity consumption in a clean production space, due to the high airflow rates needed for particular ISO classes. However, when a door is opened, a significant exchange of air (with that of the outside air) will take place. This can affect the cleanliness of air within the room until such time that the HVAC can recirculate and clean the air again.
Cleanrooms that have hermetic sliding doors can give consistent and fully predictable sealing and air leakage control over long periods. Hermetic sliding doors have a frame mounted seal that, along with special indentations in the track, uses the door’s own weight to seal perfectly against the frame and also the floor.
Hygiene, secure sealing, minimising pressure drops, protecting against contaminants and drafts, reducing energy costs, improving user safety and ease of cleaning; these are just some of the key issues that Dortek doors address.
- Dortek cleanroom doors will not warp, rot or rust.
- The cleanroom doors smooth and seamless construction means there are no ledges where bacteria can gather.
- The one piece encapsulation means that these cleanroom doors are 100% waterproof.
- Non porous and non inorganic construction

Sliding Cleanroom Doors
What our clients say
We have installed Dortek’s GRP doors for the past 12 years in 3 of our locations in Europe. The doors are ideal in production areas as they are without seams or crevices into which dirt and bacteria can gather as well as being very strong and hard wearing. I have found Dortek staff very technically competent, focused on working with me on presenting solutions to problems, and I regularly recommend Dortek to colleagues and peers in our industry.
Global Manufacturing Company
Infection control is of critical importance in our premises and, therefore, specifying the correct doors for our new operating theatres was crucial. We are impressed with the high quality and clean appearance of Dortek’s doors which are particularly suited to sterile areas. Their installation team were very professional, helpful and knowledgeable and we wouldn’t hesitate to recommend them to others in the industry.
