Windows - Looking for slim upvc frames and openers

[compact]

Hi
We're changing our windows from wood to upvc.
The frames are a lot wider than our existing wooden ones.
Frames are looking at 70mm, frames and openers (when viewed from the outside) 110mm, even wider if we get tilt and turn.

Can we get slimmer frames or are these standard sizes?

Thanks
