Hi everyone. I'm nearly finishing my modest home-cinema room, and need to find the best way to block the light from the windows. I'll use a projector, so the room needs to be almost completely dark, and equally important, I must also reduce the sound reflections coming from the glass windows. From the threads I've been reading, it seems the solution is to get some heavy cloth curtains, but I must confess this is something I have never paid any attention and have no knowledge whatsoever. To make matters worse my windows/doors are placed in the corner, which may make the task harder (at least in my mind). I'll place two images below. Is it reasonable to expect almost total darkness just from cloth curtains? I think some persons use blackout roll blinds, but if possible I'd like to avoid it. The simpler (and cheaper) the better. Regarding cloth curtains, I have no idea if I can use a curved track (is it the right name?), or if I need 2 tracks, on the corner at 90 degrees. Also, it seems some ppl use two curtains on the same track, but not sure if it's necessary something special for that. The weight worries me a bit too. Still regarding cloth types, no idea how to choose, or even where to start. There seems to be thousands of options. I'd appreciate all suggestions and tips. I'm very comfortable around computers, but in this subject I'm a total newbie. Thanks for your time.
