Install windows in Leca

but then... if you don't want to do that, then just ignore it
You've already made up your mind, so it doesn't matter what people answer to your questions.

The reason I think you should read it is because the questions you're asking are so basic that the instructions answer everything.

Just want to know why it becomes more windproof?
Does it say anywhere?

The reason for thin plastering (e.g. a slurry that is thrown on and brushed out with a lime brush) with 2 mm mortar on Leca is to achieve windproofing. However, this can also be achieved with traditional plastering of 15 mm (even better windproofing). But if you want to be completely sure, as the product description states, it is not wrong to apply thin mortar/slurry in the frame opening and brush it out. This ensures tightness behind the frame as well. However, it is not there that the wind enters, but from the outside on the rest of the masonry surface, where, as mentioned, thick plaster is applied. But if you are going to clad the inside with paneling or other materials, e.g. board materials, thin plastering is recommended to ensure complete windproofing behind panels or boards. A kitchen fan or other mechanical ventilation can otherwise 'draw air' through the Leca.

You're plastering the entire facade anyway, so you might as well do it in the reveals too.

No, it is plastered on the outside, i.e. windproofed.

we put a wooden frame around and then placed the windows in it. Good way to fasten it but not so good aesthetically. I can't recommend it because it looks ugly when you're forced to build window trim even in the plastered wall.

Do you moisture-proof the frame? More than just painted.
