What would happen to an object if you would put it in a room that is isolated to gathering any kind of information?

Lets say you put the room in a vacuum, cool it down and prevent any particles from interacting in any way possible, if that were hypothetically even possible in the macroversum, and let the laws of quantom physics rule over it?

Would the rules of shroedingers cat apply to said object?

(I'm not a student of anything but this got me thinking after reading into the double slit experiment)
