Materials
Similar to the sliding window system air-lux SW 75 Connect, a combination of different materials is also possible for descending windows. As the profiling and construction of the descending windows depends heavily on the respective requirements and specific dimensions, the standardised proportion is smaller here and the use of materials has to be individually tested and developed.
In principle, however, the same material variants as the SW 75 can be combined with each other:
| Inside | Outside |
| Aluminium | Bronze |
| Bronze | Aluminium |
| Bronze | Bronze |

As air-lux is a flush system in which the profiles are embedded in the floor, the use of wood outdoors is not possible. On the interior, however, a wide variety of woods can be used. air-lux relies exclusively on real wood instead of imitations. Here is a non-exhaustive selection of possible woods:
