Got a couple of [wooden] windows where there’s a draught blowing in even when fully closed. I’ve used P strip before which is alright but is there anything better out there?

What’s wrong with P strip?

Nothing in particular, just wondering if there’s anything better.

Thin brass strip pinned in the gap and folded to fill the gap is an old skool
Option.
