Trickle / air vents

[scrumpyjack]

New windows going in soon and we decided to have trickle vents as our

house gets a lot of condensation--kids, cooking, and widow twanky!!.

Window length is 1880mm and it will be 2/3 fixed pane with a 1/3 side opener

Where is the best place to position the vent??--in the centre of the whole

frame? or it the opener?

trickle vents tend to be fitted to the window head and usually below a knock-on piece.
