Return to Asbestos BlogEven though the use of asbestos greatly decreased after its health hazards became public knowledge in the 1970s, the extent that it was used before this time means that asbestos is still present in many products and on many surfaces. It can still be found in older homes and in some items imported from other countries restrictions are more laxed. It is still present in many construction materials and still legal to produce in items like cement. Unfortunately, it seems asbestos isn’t truly going anywhere anytime soon.
Building Materials and Products That May Contain Asbestos
Asbestos roofing materials |
 |
| These were strengthened, made more durable, and provided insulation and fireproofing by adding asbestos fibers. Since the early 1980s, asbestos has been decreasing rapidly in roofing but products that could still contain it include coverings, boards, felts, flashing, insulation, adhesives, roofing tiles, padding, and vapor retardants. |
Insulation in older houses may contain asbestos |
 |
| This can be found in areas that are harder to see, such as the attic, basement, crawl spaces, closets, walls, floors, and ceilings. Asbestos materials such as vermiculite insulation can sometimes be identified by sight, but others are very difficult to spot. This is why professional asbestos in popcorn ceiling testing (and elsewhere in the house) is necessary to ensure homeowners are not exposed. |
Paint containing asbestos |
 |
| Asbestos was added to paint to give it a thicker texture. Airborne asbestos exposure was a risk for everyone who used asbestos paint additives. This included factory workers and field workers. It was dangerous only when it was raw fiber or used as a dried paint additive. Once it was applied and dried, it was relatively stable and safe. |
Asbestos Popcorn Ceilings |
 |
| These are a style of dimpled drywall that was popular between 1945 and the early 1990s. Asbestos is likely to be present in popcorn ceilings installed before the 1990s. It was preferred for many years for its heat-resistant qualities. The EPA banned hazardous pollutants from ceiling coverings in 1973 with the National Emission Standards for Hazardous Air Pollutants (NESHAP) standards. Despite the ban, it appears popcorn ceiling materials still contain asbestos. Workers may have continued to use asbestos products that were not prohibited, and it has been reported that stockpiled popcorn ceiling materials may have contained asbestos until the 1990s. |
Sheetrock Taping Compound often contained asbestos |
 |
| Most sheetrock taping compounds, also called sheetrock mud, sold between 1940 and 1980 contained asbestos fiber. This product came in two forms and was used to fuse the seams between drywall panels once installed. |
Stovetop Pads made of asbestos |
 |
| Asbestos was used to make stove mats made from millboard and applied to protect stove tops and countertops from hot cookware. On stovetops, asbestos and metal were often combined. Home kitchens weren’t the only ones that used asbestos — industrial and commercial kitchens also used them, which means anyone working in a restaurant or food processing plant could have been exposed to toxic fibers. Asbestos fibers can be released from mats if damaged or worn naturally. |
Walls and Floors Around Wood-burning Stoves |
 |
| Asbestos was commonly used in chimneys, furnaces, and wood stoves, as well as the walls and floors around these structures. Naturally fireproof, asbestos was preferred for insulation in stoves and furnaces. However, these materials can also release asbestos fibers, which can be inhaled and cause health problems. |
Vinyl and Linoleum Titles |
 |
| Wood floors, vinyl tiles, and other types of flooring, such as linoleum, were installed with asbestos adhesives. Black asbestos mastic is one of the most extensively used flooring adhesives. Ethylene and chlorine are the main ingredients in vinyl. Asbestos is flexible, easy to clean, and inexpensive to install and replace. In addition, vinyl products with asbestos were popular for a number of years because the product can be colored and textured to mimic the look of wood, stone, and other traditional building materials for a lower cost. Asbestos isn’t used in today’s vinyl products, but other countries continue to use it, and importing it into the U.S. is largely unregulated. |
Hot Water Elements or Steam Pipes |
 |
| Hot water elements or steam pipes in older homes may be wrapped in asbestos insulation. If the covering appears to be deteriorating, it’s important to avoid cutting into it. A homeowner should leave the aging asbestos alone and wait to have it removed by a professional. |
Insulation in older houses Oil or Coal Heated Furnaces and Gaskets |
 |
| Before asbestos began to be regulated in the U.S. in the 1970s and ‘80s, it was mixed into the materials used to build furnaces nationwide. Asbestos served mainly as an insulator for boilers, burners, and hot fireboxes and allowed combustible substances to operate safely. During the last half of the 20th century, asbestos-containing materials were commonly used in construction and furnace installation. Chrysotile asbestos was the most commonly used mineral fiber. Also called “white asbestos,” chrysotile accounted for 90 to 95 percent of America’s asbestos use. |
Fabrics (Including Clothing), Tapestries and Upholsteries |
 |
| Because of its fibrous nature, raw asbestos can be spun and woven into textile garments and other tapestries and upholsteries (including asbestos on carpet). This makes textiles resistant to high temperatures, flames, electrical fires, and corrosive substances. At the same time, these products aren’t indestructible – they can be sliced, cut, or torn. Thus, they can easily be shaped as desired. Asbestos’s fireproofing capabilities made it ideal to use for protective clothing such as firefighters’ jackets and aprons and mitts for foundry workers. It was also used in fire blankets for a number of years. The tensile strength of these products was also improved when asbestos fibers were woven into other fibers. According to a 1993 report produced for the EPA, production of asbestos textiles in the U.S. ended in the late 1980s. However, they are still manufactured overseas. |
How long do these asbestos fibers stay on surfaces?
Once asbestos fibers from various products have been released into the air and begin to settle on surfaces, they can stay on them indefinitely. If they’re disturbed, it takes 48 to 72 hours for them to fall onto the surface again. During this time, the fibers can contaminate clothes, furniture, and other fabrics. The microscopic particles are sharp and durable. They can easily be carried on clothing into a family vehicle or small washroom, exposing anyone in the carrier’s vicinity.
What do you do if you suspect your home, building or product contains asbestos?
What can you do? If you suspect you have asbestos in anything mentioned in this article, contact someone about having it removed. That way, you reduce the risk of possibly contracting any of the diseases related to asbestos exposure.

If you have any additional questions or concerns related to asbestos, check out our website and YouTube page for videos, infographics and answers to your questions about asbestos, including health and safety, asbestos testing, removing asbestos from your home and building, and legal information about compensation for asbestos injuries.
If you believe that your home was contaminated with asbestos, or you believe that you were exposed to asbestos, or have been diagnosed with an asbestos illness, you could be entitled to significant compensation—money you could use to cover the costs of asbestos removal services, pay for medical treatment, and preemptively protect your physical well-being.

The largest database of asbestos information on the planet.
W.A.R.D., which stands for the Worldwide Asbestos Research Database, helps clients to narrow down when and where they may have been exposed, as well as which products may still contain asbestos. W.A.R.D. will also help indicate compensation types and how much a person may be entitled to.
