GSK Barnard Castle

GSK Barnard Castle

GlaxoSmithKline (GSK) submitted £94million plans to Durham County Council to expand their Barnard Castle plant which will see it create a new pharmaceutical manufacturing facility and associated works.


The GSK Barnard Castle site required hygienic door systems that would offer an airlock solution for the passing of raw material into production. The doors needed to offer secure segregation between production machinery and circulation routes and t was important that the doors for this project would also have to fit into restricted and limiting spaces.


Dortek provided a bespoke solution to each individual requirement with a combination of door types, as available space was at a premium.

Dortek supplied GSK with 6 Dortek Butzbach Novosprint Mono Doors, 5 GRP Sliding Doors (including 2 of Dortek new Telescopic Doors) and 4 Hinged Doors in Aluminium Frames.

For the airlocks, there wasn't a viable alternative to horizontal rolling doors as there was insufficient floor space for hinged doors. There wasn't any space to the sides for sliding doors and no headroom for vertical roller doors. Therefore all doors were interlinked in pairs to provide efficient MAL space.

Doors were installed to a cleanroom system which finished short of the ceiling so acting as a barrier, so creating barriers as opposed to individual rooms. The whole project was conducted whilst the rest of the facility was in full use, so cleanroom conditions surrounded the process.

Dortek fulfilled the GSK's expectations by listening to the brief, their requirements and advising suitable products accordingly, working closely with the walling contractor.
