I have an 18" diameter X 3' stand pipe in my yard that has a pvc water pipe coming up through it with a hose bib on the end. Because I live in a freezing winter environment I wrapped the pvc pipe with fiber glass insulation. I now want to fill in the space between the fiber glass wrap and the interior of the stand pipe with an insulation material. Any suggestions on what I could put in that space that would be a good insulator?
