ᐅ Window Frame Dimensions and Other Questions

Hello,

Here is the situation.
The opening measures 1 meter (3 feet) from the bottom of the wall to the top, and 3 meters (10 feet) from the left side of the wall to the right.
Since the height from top to bottom is only 1 meter (3 feet), it is important to keep the window frame as small as possible to maximize the glass area.
A standard uPVC window usually has about 15 cm (6 inches) space from the window sill to the start of the glass, and it’s similar at the top. This means the visible glass height ends up being around 70 cm (28 inches), which is quite tight.

Are there any options to increase the glass height to about 90 cm (35 inches)? That would leave only about 5 cm (2 inches) for the frame at the top and bottom. I have not seen this before except perhaps in department stores.
Does anyone happen to know if this is feasible or achievable?

Regardless of the frame height, the opening in the wall should be used as efficiently as possible. A traditional casement window with one sash, dividing the opening in the middle, would protrude too far into the room when open. Therefore, I am considering a sliding window.
I’m only familiar with sliding windows that reach room height, but I imagine it wouldn’t be a technical problem to implement this here.
However, I wonder about the practicality. One side of the window will probably remain fixed, right?
This could make it difficult to clean the exterior on the side that opens...
I assume there are no disadvantages concerning sealing or similar issues?
Are there no sliding windows that allow both sides to open (for example, for cleaning)?

What other options could there be? The priority is to use the opening in the wall to maximize the glass area.

All-metal windows have narrower frames, similar to plastic windows. There are also windows that are almost frameless, but these are even more expensive. So it’s purely a matter of price 😉
You can also install frameless fixed glazing.

Hello and thank you for the responses. So, frameless window glazing would definitely not be a solution.
What difference does it make if the frame is smaller?
Can you define more precisely what you mean by more expensive, for example, x% higher than a standard?

A window with fixed glazing! Or a 70-30 division.

This would likely make the frame only wider at the window.

Wall at the top and wall at the bottom, with 47 RBM hollow blocks in between, fixed window, called a ribbon window when it is 2 meters (6.6 feet) long.
