With the development of the stacking door in 1977 Butzbach laid the foundation for a successful company history.
Since construction of the first stacking door Butzbach has now manufactured and sold nearly 50.000 stacking doors. Butzbach is sure, that some of the doors installed in the early years are still in operation. One reason for that is certainly the outstanding service Butzbach offers to their customers, even years after the installation of a door. So even 20 years after the purchase of a Butzbach door all the spare parts are still available.
In order to mark the 35th anniversary Butzbach is looking for the oldest stacking door in Germany, which is still in operation. The Owner of the oldest door will receive a voucher worth 5,000 € for remediation or the purchase of a new door.
