Cover flashing
As an emergency solution, it can be placed on the panel board under the cover batten/cover board during renovation, window replacement, etc.
But it cannot be answered without knowing how the construction looks and the reason for making that choice.

In new construction, the flashing should be installed inside the wind barrier/fabric, or alternatively exterior gypsum or asfaboard, to prevent condensation and driven water from damaging the frame.
When renovating, replacing windows, etc., there are established methods that suggest it’s not possible to get the flashing behind the wind barrier without removing all the paneling above; therefore, the flashing can be placed against the wind barrier or against the nailing strip, depending on the construction.

In new construction, the flashing should be installed inside the windbreaker/membrane or alternatively, outer gypsum board or asfaboard, so that condensation and driven water do not damage the frame.
In renovations involving window replacements, etc., there are established methods indicating that it is not possible to fit the flashing behind the windbreaker without dismantling all the paneling above. Therefore, you can place the flashing against the windbreaker or alternatively against the battens, depending on the construction.

Is asfaboard still used?
Yes, Hm-hus in Gothenburg builds with it; I know several carpenters who use it.E Evalarsson36 said:
Talk to your carpenter about this; a tip is not to clash with a craftsman as they are often not very socially skilled in discussions about their craft, often due to pride, which is unfortunate in itself.
Doesn't have to be wrong in certain renovation situations. If the only option is to place on top of a panel board, then you do it.Janu78 said:
But it requires then a flashing made with a slight indentation at the top edge of the sheet, e.g. 10 mm from the edge. Where the edge is pressed against the panel board during installation. Then painting should be done so the paint goes out a bit over the sheet.
I know that many people do it this way, but that doesn't mean it's done correctly; there are many DIY enthusiasts in our long country.A AndersS said:It may not be wrong in certain renovation situations. If the only option is to place it on top of the panel board, then go ahead.
But it requires a flashing that is made with a slight inward bend on the top edge of the metal, e.g., 10 mm from the edge. Where the edge is pressed against the panel board during installation. Then painting should be done so that the paint goes a little over the metal.
And it can work depending on how weather-exposed the facade is. But if a construction company does it and the panel rots or, even worse, water seeps into the structure, it will be tough for the construction company in a dispute to argue that they've seen others do it.
