Asbestos Felt and Paper

Asbestos Felt and Paper Used in Building Materials

Because of the naturally soft, fibrous consistency of asbestos, the fireproof mineral was also made into felt for construction and manufacturing purposes until its toxicity was revealed to the public. Felt is a type of fabric made when textile fibers are compressed and heated or moistened so that they mat together. Felt was commonly made of animal hair or synthetic fibers.

Asbestos felt was used as an underlayment for floors and roofs. Paper mills also used sheets of it on which to dry hot paper pulp. The asbestos content of these products was historically 85%. Almost all manufacturers used the common chrysotile form, also known as “white asbestos.” Asbestos felt and paper easily releases toxic fibers into the air when worked with or disturbed. It poses a major exposure risk.

Asbestos flooring felt is one of the few asbestos products completely banned in the United States. Old asbestos felt remains on the floors and roofs of millions of American buildings constructed between 1900 and the 1990s. Roofers, flooring installers, demolition workers and paper mill workers were exposed.

Diseases Related to Asbestos Felt

Exposure to asbestos-contaminated felt may cause the following diseases:

In 2007, an asbestos exposure study was published in the Annals of Work Exposures and Health. It simulated work roofers performed using asbestos-containing roofing materials, including felt. Chrysotile asbestos fibers were detected in 28 of 84 air samples taken during the study.

Thankfully, it is unlikely that current roofers are exposed to dangerous levels of asbestos over an eight-hour work shift. Unfortunately, former roofers were exposed to dangerous levels of asbestos. They have developed related diseases as a result.

Occupations at Risk

Roofers, flooring installers and paper mill workers inhaled asbestos working with asbestos felt. Even when the product was new and in good condition it could release asbestos fibers during handling.

In decades past, asbestos felt products contributed substantially to occupational exposure. Occupations at risk of exposure to asbestos felt and paper include:

If you were exposed in the past, watch for symptoms such as difficulty breathing, chest pain, abdominal swelling and fatigue. Workers diagnosed with related diseases should see a doctor to ensure they receive the best treatment possible.

It is important to hire a licensed asbestos abatement professional if you believe asbestos felt is in your home or workplace.

What Was Asbestos Felt Used for in Construction?

The construction industry primarily used asbestos felt to produce roofing and flooring products. It was also used to make paper.

The primary applications for asbestos felt included:

Installing, repairing and removing asbestos felt and paper products released asbestos fibers into the air. These fibers are easily inhaled, but the body struggles to remove them all. The fibers accumulate in the body over time with repeated exposure. Over decades these fibers cause damage and inflammation that leads to cancer.

Companies Connected to Asbestos Felt and Paper

Companies that manufactured asbestos felt include:

Other companies that manufactured asbestos felt products include:

Several of these companies were forced into bankruptcy because of asbestos lawsuits. To reorganize through bankruptcy, they had to create trust funds to compensate asbestos victims.

Compensation for Exposure to Asbestos Felt and Paper

Workers have filed lawsuits against manufacturers of asbestos products. These people were diagnosed with diseases like mesothelioma and lung cancer. This sent many companies into bankruptcy.

Another major manufacturer of asbestos flooring products, Armstrong World Industries, was driven to bankruptcy in 2000 by the volume of lawsuits filed against it. As part of its reorganization, it established the Armstrong World Industries Asbestos Trust in 2006 to provide asbestos compensation to present and future claimants. According to the trust’s 2014 annual report, it paid almost $100 million in claims that year and its total value was about $1.8 billion.

In addition to lawsuits and trust fund claims, other forms of compensation include VA claims, Social Security Disability and grants for treatment or travel. An experienced mesothelioma attorney can offer the best guidance on the types of compensation for which you may qualify.

Abatement and History of Asbestos Felt

If roofing or flooring installed before 1980 must be repaired or replaced, a sample of the underlayment should be tested for asbestos before the work gets underway. Consult a trained asbestos abatement professional before doing any work that may disturb an asbestos felt product.

Asbestos felt is friable, making it a particularly hazardous product no matter the percentage of asbestos content. Most asbestos felt in homes and businesses today is encapsulated under floor tiles and roof shingles. The safest thing to do in many cases is to leave it that way so asbestos fibers remain trapped.

In the early 1900s, a new construction method called built-up roofing became popular. During this process, several layers of fabric covered with tar or asphalt were laid down on top of one another. Asbestos felt became the primary material used in many flat-topped buildings.

Materials used in flooring installation also incorporated asbestos felt. Linoleum, asphalt and vinyl floor tiles all offered cheap and durable flooring solutions, and asbestos felt products were available as backing materials for all of them.

The rise of the office worker brought with it the advent of the modern paper industry, which found yet another application for asbestos felt. After trees are processed into wood pulp, the pulp must be dried before being made into paper. Laying the pulp out on sheets of asbestos felt allowed it to be dried at a high temperature, increasing the speed of production.

By the 1980s, however, corporations could no longer cover up the link between asbestos exposure and fatal diseases such as asbestosis and mesothelioma. As with most asbestos products, the use of asbestos felt has largely been phased out in the United States, though it remains a threat to workers and homeowners renovating old floors and roofs.
