Panoramic windows - Are the window prices affordable?

In our house, I usually set the heating. Unfortunately, my boyfriend also notices every degree I turn it up and sometimes secretly turns it back down again. However, I always notice it right away... :-(

That bastard!

The Ug value, i.e., the heat transfer coefficient of the glass panes, is 0.5-0.6 for triple-glazed windows, while the Uf value (frame) is 0.9-1.0. With warm edge spacers, standard (70mm) profiles for large-area elements result in Uw values (whole window) of 0.8 to 0.7 for thicker profiles, and even 0.6 according to the Passive House standard. Compared to a standard of 0.24 for exterior walls, this is of course significantly higher, but not dramatic, and especially for fixed-glass elements, the additional cost for thicker profiles and glass is moderate.

South-facing triple-glazed windows with warm edge spacers (i.e., plastic spacers between the panes instead of aluminum/stainless steel) can also have a positive energy balance! Over the entire heating period, the solar heat gains are greater than the losses through the windows. Of course, the windows must be properly oriented (south), shaded from above in summer, and the irradiated surfaces must have a potential for heat storage/heat capacity (no wallpaper and no carpet).

For a west orientation, I would advise against large, especially tall window fronts.

As a general guideline:

North: small windows, no shading necessary
East/West: medium-sized window areas, preferably with variable shading, ideally external
South: large areas, tall areas, constructive sun protection through eaves, overhang, etc.

In addition to the cost of the window elements themselves, there are the installation costs and, for assembled elements, coupling profiles, and for stacked elements or elements with doors, also static couplings.

The additional costs for triple glazing compared to double glazing, and especially for warm edge spacers, almost always pay off.

Can you show photos of your giant windows?
Also, please include the size and the approximate price?
Thank you

Not as big, but still 2.5m high and 5.15m wide:
Base price: 1800€ (triple glazing Ug=0.6, warm edge Swiss Spacer grey, grey foil decoration outside, Drutex IGLO 5 Classic Profile 70mm)
Plus two static coupling profiles on the right and left of the double door (+2*200€)
+Installation according to RAL with foil inside (visible in the picture, not plastered yet), compression tape outside about 900€ (proportional from total order, without plastering work)

The division of the fixed side elements would not have been necessary and is also not optimal in terms of energy, but site management wanted it for aesthetic reasons.
Orientation is SSW with about 1m roof overhang directly above. On the north side we chose the more energy-efficient 82mm profiles, on the south side that would have been about 1000€ more in total for the large fronts (there is another one in the adjacent room).

Oh yes: Old building and construction site, so neither tidy nor clean.
There will be no cold air at the window either - see radiator connections on the right and left - the old 60 cm high radiators have already been replaced by only 30 cm high heating strips which should be sufficient with the new windows, on the other side of the room there is another radiator and the room is called "fireplace room"

Here is an example from the adjacent room, 4.8m * 2.2m, how NOT to do it. Without a significant roof overhang, also with SSW orientation (photographed at sunrise, leveling fill for the dry screed is lying on the floor). The windows are frosted outside in the morning! and from noon on the sun shines fully on them even in summer. (there will still be a canopy/shading installed there, but here in northern Germany it is also less often a problem with too much sun exposure.)

Radiator solution here on the right and left of the window with vertical radiators. In this case, however, the difference between the U-value of the window and the wall is smaller, U-value of the wall about 0.5 (built in 1960).

If the sun shines in winter now, no one needs to heat the rooms between 11 a.m. and 3 p.m.
Overall, we have 52m² of window area on 135m² of living space in our house. Energetically certainly not optimal, but not a bunker, rather LIGHT.
Does anyone know Drutex?

That is not the panoramic window I have in mind. Maybe it looks different in the new building. I thought you meant something more like this

What do you think, how much would a window in this style cost (approximate ballpark)? The size of the individual window should be about WxH 2x3m. I understand that something like this facing south is only feasible with a blind. The eaves won’t save you in summer with 2 floors...
