How to recognize vermiculite building insulation that may contain asbestos fibers. 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. 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. 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 FIBER-CONTAINING - Examples of materials that might contain asbestos fibersVERMICULITE INSULATION - Vermiculite building insulation may contain asbestos
Depending on the mine from which this mineral-based insulation was obtained, it may contain asbestos fibers and could present a hazard in buildings, especially if disturbed during renovations. The U.S. EPA has photos of the original bags in which this product was shipped - you're not likely to see these bags in a home, though I've found them on occasion as you'll see in my photo above. Vermiculite insulation has an R-value of about 2.13 per inch in buildings. As we discuss at our notes on other loose-fill insulations such as mineral wool or cellulose, any building insulated with loose-fill or spray-in insulation may benefit from the ability of these loose materials to fill gaps and openings more uniformly than might be found if sloppy workers are careless about installing insulating batts. Drafty insulation installations can cause more heat loss than is made up for by differences in insulation R-values. For more details about the inspection and detection of concerns with fiberglass building insulation, see: Our separate websites on Fiberglass building insulation and or series of articles about HVAC duct work defects contain in-depth discussion about possible air quality and health concerns which may be associated with exposure to fiberglass dust.To compare insulating material R-values of fiberglass in various forms as well as other insulating materials, see our Table of Properties of Insulating Materials Use links just below or at the left of each page to navigate this document or to view other topics at this website.
