Opening types for windows and doors

Opening times for windows and doors can significantly influence the possible uses such as ventilation, cleaning, shading and decoration. The most common are windows and doors that open inwards towards the inner space of the room. In our product assortment, we have doors that can be opened outwards. Here are the different opening options at a glance.


Explanation of terms

Transom profile

The transom profile is connected to the window frames. Thanks to the transom profile double wing windows are divided into parts visually. This means that the transom is fixed and can't be opened with the wing.

A sill connection

A sill connection is a component of the wing. Seen from the outside it looks exactly like the transom profile. However, it isn't fixed, but it rather opens with the window wing. This means that the window isn't separated into several parts.
