The refurbishment of old hangars, in both technical and optical respects, requires flexible solutions that can be adapted to the local situation and allow a further economical use of these buildings.
In order to adapt two old NATO hangars at the Chambley airport to the most diverse requirements of the future, the responsibles decided for Butzbach hangar doors, which were individually adapted to the existing buildings.
High light transmittance
The client put great emphasis on a translucent door filling in order to minimize the electricity cost for lighting in the hangar. The translucent fibreglass in the colour emerald-green allows natural day-light to penetrate glare-free into the hangar. Artificial lighting can almost be dispensed with during the day and yet, the people who are trained as technicians for aircraft engines in one of the hangars, have optimal lighting conditions for their training. The contrast of the door colour with the remaining facade surface in grey also gives the hangar a modern appearance.
Manually operated door system
In order to keep follow-up costs as low as possible and thus ensure economical use, doors with manual operation were selected. Thanks to the lightweight construction made of corrosion-resistant aluminium frame profiles in combination with fibreglass as door filling, even door leaves in large dimensions can be effortlessly operated by hand. Due to this currentless operation, a permanent availability of the door systems is guaranteed. The guide rails of the previously installed door system could be preserved, which saved additional work on the foundations.
Realisation of the largest possible opening width
By means of a lateral extension of the rails on the hangar for the park position of the individual door leaves (which can then be „parked” at the side next to the hangar) almost the entire hall width is available for opening. This offers the greatest possible flexibility in the use of the hangar area.
