Panoramic windows - Are the window prices affordable?

I am not entirely sure anymore whether the problem was the radiant cold or the draft (caused by the cold descending air). But what I do know for sure is that there was/is a problem with cold and they would prefer to have air outlets in front of the windows..

Exterior wall? Why should this difference between pane and wall outside be relevant for radiation cold inside?

An exterior wall has two sides: inside and outside. An interior wall also has two sides, both inside
Now guess what I compared

I guess you compared the inside of the exterior walls with the inside of the windowpane?

I believe that we men cannot understand that. Women can be very sensitive when it comes to drafts and temperature differences. When adjusting the heating, for example, my wife noticed every degree that I changed on the [Vorlauf].

Usually, I am the one who adjusts the heating here. Unfortunately, my boyfriend notices every degree I turn it up and sometimes secretly turns it back down again. However, I always notice immediately... :-(

A friend of mine has also installed an extremely large glass front spanning two floors. To make the height have an effect, the open space has to be quite large – that space also costs money. Otherwise, her biggest concern was actually the heat protection. However, she doesn't live there yet.

Fixed plastic – 300 x 260 cm – 750 EUR

Aside from everything else. The price won’t work. Get an offer, but don’t be surprised if you end up paying 5-6 times your 750. Internet price and what the local market charges are two different things.
