A presenter on a documentary I saw the other day talked about the shiny reflective material on the celling of a skating ring "reflecting the cold", this is not right is it?
I mean only radiation can be reflected, I thought, not the lack of it.

It does sound wierd, since it implies that the "cold" rises.

Mirrors are mirrors. If they're directed towards cold, then they reflect the ambient temperature of their target. If that's 0 deg C, then the target appears to reflect 0 deg C. It's not "reflecting cold," but rather, allowing the heat in your area to be sunk in a cold area.
