ᐅ Replacing windows while preserving the window reveal, preliminary selection of suppliers

Hello everyone,

we are about to purchase and renovate a single-family house. The old wooden windows will be replaced with floor-to-ceiling wooden (aluminum-clad) windows.

Issue 1: All local companies we contacted offer windows from (in-house production or) various manufacturers, none of which I have found any references for here on the forum. Therefore, my question is whether there are any experiences available and how we can generally approach this topic and make a preliminary selection, or are the differences in these areas rather minor? The list includes:

• Tryba
• Unilux
• Wertbau

Issue 2: The existing windows have an outer reveal and roller shutters that are to be retained. The window companies we have spoken to so far say this is possible but of course cannot guarantee it. However, I am concerned that either the reveal will be significantly damaged or the whole installation will be done in a makeshift way and in no case come close to the original condition in terms of quality, sealing, or appearance. Does anyone have any idea if this can even work together with a wooden-aluminum window variant and such a reveal?

Grateful for any advice...
🙂
