Glass Curtains

It's a while since this was last discussed so sorry for a new thread but thought it needed an update.
There are several companies recommended and I have taken those names and numbers.
Now, my question is, how much do these things cost? I note from a previous thread that some on here paid 1800 euro. However, that is for 6.5 sq metres whilst another quotes 210 per sq m so cheaper .
Now, 6.5 sq m is just over 3x2 so quite a small space. The one we are looking for is for a balcony 7m long and about 2.5 metres high (may be lower than that, depends on how high they go up). That would make it pushing 4000 euro at the lower price or over 5000 at the higher one.
Anyone had these fitted (not keen on them, to tell you the truth, but would be nice to keep the draughts out and sit outside during the winter months) and, if a largish balcony, how much did they cost?
TIA

Considering having Euroguard Glass Curtains fitted on our balcony, has anyone got experience of this company? How good is the product? How does it perform in bad weather ie wind and rain?

We had Euroglass fit our glass curtain in February ‘16. The addition of the curtain has reduced draught and has slowed the transmission of cold to the front of the house. But the main benefit are that, in the Sun, it absorbs the heat and gives us a warm room to spend the day in. Secondly, you can fold the panes back, effectively throwing the doors open, to greet the summer.

Matt, the owner’s son (he might well be the owner now) did the instal so he has a vested interest in getting it right, first time, every time.

Oh and at a good price too for two jobs
