To ensure that all Reynaers systems remain stable and of high quality even after one hundred thousand movements, we carry out cyclic tests. On the set-up, the windows and doors are opened and closed in cycles. All data are stored and analysed, enabling us to calculate durability.
- Average cycle for windows: 20,000 movements
- Average cycle for doors: 200,000 to 1,000,000 movements
