Remove ventilation in the facade, what do I do with the hole?

[Eklundh]

Hello.
I have an old vent in the facade that ends up in the middle of the wall in a kitchen we are renovating (recently purchased house).

From the outside, I plan to remove the vent grille and then brick in 2 bricks (I have some left from the old window opening) so it looks aesthetically pleasing with everything else.

On the inside, there will be drywall/smooth fabric that will then be painted.

My question is, how do I handle the hole in the facade behind the brick? I would like it to be done correctly to avoid any potential issues with moisture, etc.

Pack fully with insulation

When I removed a couple of valves, I cut a piece of Styrofoam and stuffed it in and packed with insulation around it. But of course, it depends a bit on the wall construction.

Depends a bit on how the wall is constructed. If there is an air gap behind the brick, you should probably try to maintain it even where you cover the hole.

There is an air gap behind the brick façade that I intend to preserve, but do I need any wind barrier/vapor barrier or similar between the air gap and the insulation towards the inner wall?

Yes exactly, try to seal the hole in the same way the rest of the wall is constructed. I would try to glue/seal some form of board facing the air gap (exterior gypsum or some oil-hardened board), then insulation, and then tape building plastic or paper depending on what is on the rest of the wall, and then gypsum.

I would have attempted to glue/seal some form of board towards the air gap (outdoor plasterboard or any oil-hardened board) then insulation and then tape building plastic or paper depending on what is in the rest of the wall and then plasterboard.

Air gap / Wind paper on oiled board / Insulation / wind paper / underlaying paneling / plasterboard (the underlaying paneling is because the rest is built that way.)

Thanks for the help and especially the confirmation that it works.
