Underground Pipe Insulation

K-Flex Insul-Lock
pipe insulation, available online at, provides freeze protection
and minimizes heat loss and heat gain in pipes. A pre-slit adhesive strip makes
installation easy. Watch our installation video here. Insul-Lock comes in
six-foot lengths for a variety of pipe sizes, with wall thicknesses ranging
from 3/8” to 1”.

The insulation can be
buried underground if you take proper precautions. To prevent
water absorption, bury insulation that is above the water table in 3" to 5" of sand. Below the water table, encase the insulation in a conduit (concrete, PVC, etc.). This method is optimal for all installations. In
order to guard against compression of the insulation, the manufacturer
recommends using insulation a size thicker than would be needed for above-grade
