I'm looking for advice on the best way to mount a retractable awning (around 80lbs) to my exterior wall, which is stucco over 2 inches of styrofoam and two sheets of 1-inch drywall. Behind that, there are metal studs. I need to secure a block that will make the awning brackets flush with the exterior wall, which means the block should be about 4 inches deep to reach the metal studs or the back of the drywall. I previously attempted using wood, but a strong wind caused the awning to pull out the screws. This whole setup is on the 4th floor, making it challenging to access. I want to minimize damage to the stucco, hence the 2x5 inch hole I made for the bracket. Any suggestions on how to secure this awning effectively without compromising the wall's structure?

It sounds like you've really got a complex situation with that wall. I recommend mounting a solid block in that 2x5 inch hole and then attaching your awning brackets to that. Make sure you waterproof the block to avoid any water damage. Just be careful not to damage the foam insulation—it’s critical for your wall’s energy efficiency. Maybe consider using some construction adhesive alongside the screws for more stability? Good luck!
Metal studs in a residential wall can be unusual! But based on your setup, you might want to reconsider whether you should attach it at all. Those foam panels - they provide a lot of insulation. If you compromise them, it could affect your heating and cooling costs. Maybe think about a standalone awning instead, away from the wall? It might save you some headache in the long run!
That's a fair point! A standalone structure might be easier to manage and safer overall.
Definitely! Waterproofing is key. You could also look into using metal brackets for added strength.
