Sealing a facade vent - how to do it best

[pjop]

Hello,

We have changed the floor plan, and where the kitchen used to be, we will now have a study. At the same time, we will be installing mechanical supply and exhaust ventilation, so we no longer need the old vents.

How do we best seal off the old facade vents to avoid moisture problems?

The construction is brick and wood.

Thank you in advance

Close them? With a bit of silicone or latex caulk in between, it becomes completely sealed.
You can remove them, but then you have to repair it, and it often shows more than if you leave them.

Thank you for the response.

I was unclear and meant to remove it, as we will put new plasterboard on the inside. On the outside, the mesh can remain.

But how should we fill the hole?
Could a "LUX" sheet used in the bathroom with silicone sealing and then insulation work?

Anyone have any idea?

Do you really want to close them? I used foam sealant. Placed paper on the outside (behind the grid) sprayed foam sealant from the inside. After 2 days, smoothed it out and applied construction plastic and drywall around it. Putty and paint.

Thank you for your reply!

Is there no risk of moisture seeping in if I only use paper and sealing foam?

You can always check how to use foam when installing windows. And no moisture gets in. Use the same principle and it will be fine.
