Blocking up trickle vents without using expanding foam?

[Flipjango]

The trickle vents in our 2nd floor loft bedroom are ridiculous - even closed it blows a gale up there when there's a storm like last night which makes the room freezing even with the heating on full blast, and crazy noisy. The blinds were blowing around last night So I'm going to block them up. I don't want a huge discussion on ventilation please, it's my house so I'll take the risk. We have traditional Edwardian timber sash windows in lots of rooms, and a wooden front door so I don't think we've got any issues with ventilation, plus we have two velux windows in the same room that both have openable vents should we need to. So I just need to block up the cr@ppy trickle vents that don't close properly on the casement UPVC windows to stop the draughts and noise.

Because it's high up and the external window frames are black, and there is a pitched roof extension below I really can't do anything from the outside as you can't get a ladder up there. I don't think I want to risk trying to pump in expanding foam as I won't be able to get the outside to clean off anything that might leak. So I need to tidiest option that will stop the draughts, hopefully insulate a little, and be able to be done entirely from the inside. Gorilla tape is an option, but anything I can do to fill the holes?

Thanks

buy some foam pad, cut it up and stuff it in.

Thanks, do you have something specific you could suggest please? Searching foam pad isn't helping - there's too many different options. Thanks

Cotton wool, rockwool, loft insulation, an old sock, anything, tape it up and refit the vent

We use old packaging foam. It's a bit like polystyrene but more plastic and less crumbly. Lots of heavier items get delivered with it. Cuts with a knife or scissors. Gets stuffed in place in winter, comes out again in spring.
