I hired a handyman to wall mount my 75 inch TV on the party wall of our townhouse. The wall has 2 layers of drywall (about 1.5 inch total thickness) on steel studs, and has a few inches space behind it that’s filled with insulation, followed by the drywall of the neighboring townhouse. Some spots seem to have 2 studs adjacent to each other (or wider studs). There’s also some kind of horizontal fire barrier/break in certain areas.
The handyman managed to get 2 studs, but the rest of the screws are in the drywall. The wall seems to be supporting the weight of the TV fine so far (it’s been a few weeks), but I’m wondering if this will hold up long term. Appreciate any advice from this community!
