Zen
A 35mm edge that frames the hole and clearly defines it.
Visually, only a slightly contoured edge is visible, highlighted by a shadow created by the gap between it and the wall surface.
This exposed piece is designed as a removable joint between the window frame and the wall, so that it can be easily maintained as needed. There is no longer a difference between the subframe and the frame: they are a single element, installed during the rough-in phase and protected until the end of construction. The interior side has no trim.
