I have a few runs of radiator pipes that are going through unheated areas in my crawlspace & entryway. I went to the home depot and bought some frost king foam pipe insulation that was rated for up to 210 degrees - but the largest size that they had didn't fit. My pipes are 1 inch thick.
does anyone know of a pipe insulation that would fit 1" iron pipes that reach up to 170 degrees of heat??
thanks for any help!
