Automatic attachment for a Louvre vent, fits most louvres.  Its fully adjustable to open over a range of temperatures.

Some drilling is required to fit.

Q. Can these auto vents be used with a double opening window, should I buy 2 of them?

A. A double sized (1200mm + wide) single vent would require 2 of these Auto-vents. I would recommend the stronger BAYLISS XL auto-vent openers for a large vent like this for extra reliablity during windy conditions.
