This article provides examples of examples of unusual uses of asbestos insulation material in buildings, most likely also
hazards that should be evaluated. 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.
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.

visual detection of asbestos in and on heating and cooling system ducts and flue vents. Also see Micro-Photographs of Dust from the World Trade Center collapse following the
9/11/01 attack. Links to U.S. government and other authoritative research and advice are included.
ASBESTOS PAPER DUCT INSULATION Asbestos pipe insulation, found under attic floor as house insulation
This unusual "attic insulation," made of corrugated asbestos "paper" laid flat, was in the floor of a 1940s house in New York state.
We speculated that the installer had a source of "free" insulation and that it was installed before the asbestos scare.
Asbestos Gas-Fireplace Materials in Old Houses
This pre-1900 gas fireplace found in a Minnesota home used tufts of asbestos fibers to support the heating flame.
