- Q.What material can be
used to re-insulate steam pipes after the old asbestos
insulation is removed?
A.The most common insulation now used on
steam pipes is molded fiberglass sleeve with a plastic or fabric
cover. This material is widely available from plumbing and
heating supply houses. The fiberglass sleeves come in precut
lengths for different pipe diameters (measured as inside
diameters), and usually have self-sealing tape attached to seal
the cover.
