Which plugs for awning mounting wooden stand 8cm wood fiberboard

Hello,

I would like to attach a 4m wide awning with a 3m projection to our house. Now I am considering and looking for the possible mounting options. The wall construction from the outside is:

- 3mm synthetic resin plaster
- 80mm wood fiber insulation board
- 200mm mineral wool insulation
- 200mm wooden frame construction

Of course, I would not go into the normal outer wall, but would make the mounting on the floor joist, which is located between the floors directly after the 80mm wood fiber insulation board.

How and with what would you attach the awning at this point?

Best regards,
Jörg

Well, simply with long thick screws directly into the wooden construction, without [dowels]

Yes, definitely, but how do I bridge the 8cm wood fiber insulation? On the one hand, quite large shear forces act on the screws, and on the other hand, I would compress the insulation when tightening the screws. I also still have to seal the whole thing tightly.....

Hm yes, you can't pull against the insulation board, for example with a hanger bolt.

I would say cut out the insulation and fit a spacer.

Maybe someone else has a better idea.
