Insulating steam pipes in basement

The steam pipes in the basement of my brownstone are uninsulated. The basement/ground floor get very warm, but upstairs takes quite a while to heat. I am interested in insulating the pipes. The main pipes coming from the boiler are 2 1/2″ diameter. What is the best way to insulate them? Looked at options at Lowes (paper-wrapped, split fiberglass tubes only went up to 2″ vs foil covered pipe wrap vs bare fiberglass wrap).
Any ideas appreciated.
