Our site offers impartial, unbiased advice without conflicts of interest. We will block advertisements which we discover or readers inform us are associated with bad business practices, false-advertising, or junk science. Our contact info is at inspect-ny.com/appointment.htm.

This page illustrates abandoned and partly-covered-up asbestos pipe insulation in buildings. Materials like this should have been removed during asbestos abatement, and so form an indication of amateur workmanship, raising the question of asbestos particle contamination in other building areas.

This document assists building buyers, owners or inspectors who need to identify asbestos materials (or probable-asbestos) in buildings by simple visual inspection. We provide photographs and descriptive text of asbestos insulation and other asbestos-containing products to permit identification of definite, probable, or possible asbestos materials in buildings. Also see Asbestos HVAC Ducts a field identification guide to visual detection of asbestos in and on heating and cooling system ducts and flue vents.

Asbestos pipe insulation, still in use or abandoned on building pipes, compared with fiberglass pipe insulation

Photograph of asbestos pipe insulation Photograph of fiberglass pipe insulation

The pair of photographs shown here assist in distinguishing between corrugated asbestos paper pipe wrap (photo on the left) and fiberglass insulation pipe warp (photo at right). Look carefully at the end of these wrapped insulation sections to see the difference. In the photo of fiberglass pipe insulation, I peeled back a little of the white-painted outer fabric to show the yellow fiberglass interior.

The photograph shown at the page top is some "new old stock" corrugated asbestos pipe insulation that was never used - just left in a basement ceiling. Look closely at the photo as it is a clear example of the visual characteristics of the corrugated-paper-like asbestos wrap which was used along the lengths of heating and other plumbing pipes in buildings.

While an expert lab test using polarized light microscopy may be needed to identify the specific type of asbestos fiber, or to identify the presence of asbestos in air or dust samples, many asbestos-containing building products not only are obvious and easy to recognize, but since there were not other look-alike products that were not asbestos, a visual identification of this material can be virtually a certainty in many cases.

A professional asbestos removal company would not have left these un-used asbestos pipe insulation sections "stored" here.

ASBESTOS FOAMED-OVER - Asbestos pipe insulation, insulated over with spray foam

Asbestos heating pipe insulation

Here's an example of an insulation retro-fit using spray foam insulation. A professional would not have left this asbestos pipe insulation in place. Perhaps more of this material will be found elsewhere in the building. If a section of asbestos insulation were found to have been totally encapsulated by the new spray foam insulation, such as in a wall cavity, most experts would be expected to recommend that it be simply left alone.
