Window dimensions / tilt window / turn window

Hello,

the following problem
Narrow windows (H = 60cm, W = 240cm) were planned for our house (1 sash).
Now it has turned out that this is not possible with triple-glazed windows/steel reinforced.
Are there systems/possibilities to install windows in these dimensions that can be rotated/tilted etc. for cleaning purposes?
Or do we really have to switch to 2 sashes – which I don’t like visually at all :-(

Hello,

For our house, narrow windows (H = 60cm, W = 240cm) were planned (1 sash).
Now it has turned out that this is not possible with triple-glazed windows/steel reinforced at all.

Looks like a salesperson played architect again A light strip (LB) of this size makes no sense to open with one sash; as triple-glazed it also becomes much too heavy.

If you have space for an LB of this size, you also have space for 2 LBs in the total width of the originally planned window including masonry: 2 x 0.60 x 1.00 m. This would meet your desire for tilt-and-turn possibility, not significantly affect the appearance, and the weight would not matter either.

Kind regards

Regarding making the windows smaller, we received the response from the site manager, "Mr. XY does not want that!" Since the windows were not planned as casement windows but only as tilt windows (removable for cleaning), according to a technician's statement, the planned dimensions are also possible (just not with steel-reinforced windows, but for example through the use of fiber composite (RAU-FIBRO)). Our construction specification only states: windows made of plastic, triple-glazed. In the construction plans (not dimensioned, but at a scale of 1:100 and also attached to the contract / signed by all) the windows are drawn with the mentioned dimensions. The developer has already changed the windows on one of the houses to 2-sash without consultation. Does it make sense to go to a lawyer with this? In my opinion, the signed plans should be binding, shouldn't they? The developer's response regarding the contract text – "Changes that are equivalent or technically necessary, and changes that must be made due to official requirements, are reserved" – does not really count for me either. Since we included it as an addition (only after prior consultation; and the notary also pointed out that these must be reasonable...) and we also found judgments that declared this contractual clause null and void.
