Cost of windows and doors in 2017?

This thread, while excellent, is now 6-7 years old.

Would anybody have estimates and advice for 2017? I need 7 double windows, a patio double door (are french doors cheaper?), a back and a front door.

In terms of quality, what should I be looking for and for what price? I found this guide to windows and doors from 2014 very informative:

In a typical three or four-bed semi-detached house with a decent front door, patio or sliding door, back door and six standard windows and two or three smaller-sized ones, budget approximately €10,000 for supply and fit of good quality uPVC windows and doors.

Expect to pay €14,000 for the same in alu-clad, with factory timber somewhere in the middle....Triple-glazing is becoming standard practice and argon gas infill, low-e coatings and warm spacers have all been introduced...

Would these prices still be about right, and would it be much more for triple-glazed windows?

Just did job with 8 triple glazed PVC windows supply and fit 5000 euro. Doors are more expensive 1400-2000 each.
French doors 2500 at least.
It seems to me a lot of people are buying PVC doors for price of composite ones, but remember composite costs more.
