Can anyone recommend a source for patio/balcony doors?

We are currently rennovating our flat in Andalucia (close to Marbella) and want to install a folding glass door to our balcony, so that when the door is open it can be folded back against the wall and the entire end of the room is opened up to the outside.

Unfortunately our builder has been unsuccessful locating such a door, and is very keen to install a conventional sliding patio door, which would mean that half the wall is blocked off at all times (in you see what I mean - very difficult to describe clearly).

I can find lots of UK suppliers which produce exactly what we are looking for (the doors usually seem to run on tracks), but none have Spanish distributors, and have failed to find a Spanish company on the internet.

Does anyone have any advice - we would be most grateful for any leads?

Thanks in advance

I can't help you Spanna, but try the good folk at andalucia.com as I'm sure someone will be able to point you in the right direction.
