Pipe Insulation for One-Pipe Steam system - Homeowner

I am new to steam heat and am trying to learn as much as I can to solve some of the issues I am having. I noticed talk about insulating the pipes, but when I look at the hardware store, none of the insulation tubes are the correct diameter for my pipes. Where can I get the proper size of insulating tubing for the larger (approx 2 1/2 inch) pipes?
Thanks for your help.

    Plumbing store

    I went to my local Plumbing store the hardware stores don't carry the correct sizes. You can also order them online. www.statesupply.com

    Hope this helps and happy steaming

    I used

    A roll of fairly thin 3" wide fiberglass insulation that can be found at both Home Depot & Lowes. I think it is made by Frost King. 50 ft for $4 bucks. If you go around a few times. it seems to work. At least my basement as cooled down alot and i can grab hold the pipes with no problem where they used to be alomst red hot.
