Near Boiler Pipe Insulation — Heating Help: The Wall

I went to a big box store and bought 1/2", 3/4" and 1" black foam insulation for these pipes. I also got some 1 1/4" fiber-glass stuff for the largest pipes. These seem adequate for my system; it certainly heats my garage less than my old oil burner did. These are all 1/2 inch wall thickness and I imagine they would be inadequate for steam systems.
