Is sand a good thermal insulator?
Is sand a good thermal insulator? Saturated sand has a thermal conductivity in the range of 2-4 W/m-K which causes the sand layer thickness to go astronomical. Thus it can be shown that sand is a good replacement for fiberglass pipe insulation in underground, direct buried applications. It’s easier to install and costs less. Does […]
