Need advice: upgrading from foam ball setup to real ball sim in a multifunctional room

I started building my sim with the idea of only hitting foam balls. I made a frame with PVC pipes, but honestly I’m not convinced with the experience.

Now I’m planning how to upgrade it into a “real ball” simulator, while keeping the room multifunctional and (very important) avoiding broken windows.

Here’s the setup I’m currently considering:

• Impact screen: 118" x 118" from Temu (~€100). I first bought a gray one, but it only looks decent if you’re perfectly aligned with the projector — I wouldn’t recommend it.
• Side protection: Option A: mount two ceiling slides and hang photography backdrops/curtains about 30 cm (11") from the walls, mainly to protect the side window. Option B: skip the slides and just use steel rods, similar to what u/Next_Ad3660 did here.
• Projector: I have a cheap one from Temu for now, but I’d like to install a proper ceiling-mounted projector. The challenge is that I only have 2.40 m (94") from the screen wall to the furthest possible mounting point. Is that enough for a decent throw ratio and image size?

Room dimensions:

• Wall available for the screen: 3.40 m wide x 3.20 m tall (11 ft x 10 ft).

Any advice from people who’ve done similar setups would be much appreciated 🙏
