Fiberglass insulation made for pipes. If your mains are 2" you'll need 2" pipe insulation. If your returns are 1-1/4" you'll need 1-1/4" pipe insulation and so on. Home depot has the stuff but at twice the going rate. Try to find an insulation distributor in your area to save a few bucks by buying direct at the source. It may be a couple to a few hundred bucks depending where you get it and how much you'll need. Shop around. Good luck!
