Asbestos was still used as a fire retardant and as an insulator until the 1980s. It was versatile and affordable. You could use it in tiles or blow it with vermiculite. In this article, you’ll learn about the difference between cellulose and asbestos insulation.

The difference between Asbestos and Cellulose

Asbestos Insulation

Many people don’t know that asbestos is a natural mineral. Asbestos is flexible and soft, but it also has excellent corrosion resistance and heat resistance properties. For nearly 40 years, asbestos was used in construction as an insulator or fire retardant starting in the 1950s. You will find asbestos in older houses and buildings. It can be found in tiles, grout, drywall, and the attic. It is safe as long as the walls are not damaged or have no cavities that expose asbestos fibers. It can pose a serious health risk if asbestos particles are released into the air and reach your property.

Cellulose Insulation

Dry cellulose, also known as loose-fill insulation, is the most popular form of cellulose insulation. To blow the cellulose into walls through holes, builders will use a blower. It can also be used for filling wall cavities. Builders use wet spray cellulose to fill walls that are newly constructed. There is a primary difference between dry and wet cellulose. Water is added during the spraying process. It provides a better seal to prevent heat loss.

Understanding The Differences

Now you know the differences between the ingredients. However, they look very similar when inspected. It is different insulation, but it has similar problems with vermiculite attic insulation. It is very difficult to determine if asbestos is present. It is best to not touch the insulation but to have a professional extract sample to confirm whether or not it contains asbestos. You should seriously consider whether to implement a program for asbestos management or completely eliminate asbestos.

What You’ll Need To Do

If you have more than 10 square feet of asbestos, it is time to hire a professional abatement company. You are at risk of contamination if you handle larger projects.

A professional contractor will safely and quickly remove asbestos from the area. Barriers around the work area will be set up to protect tenants from being in direct contact with asbestos. To prevent the asbestos fibers from spreading, reverse airflow will be used. The asbestos will be removed using special protective equipment.

Asbestos, OSHA & AHERA Training

Since 1988, the Asbestos Institute provides safety training that is EPA- and Cal/OSHA-accredited. Experienced instructors will ensure that participants receive the highest-quality refresher and initial training, including OSHA 10, hazmat training, and asbestos certification.

How do I know if I have asbestos insulation?

Any insulated area of your home may contain asbestos-containing material. Look for areas most susceptible to heat transfer when trying to identify and search for asbestos insulation. This is where insulation material may be found, and it could contain asbestos.

How toxic is cellulose insulation?

The E.P.A. considers it a nuisance dust. The borates used to treat the cellulose are safe for humans. Fiberglass insulation is known to be carcinogenic and the toxic smoke from smoldering foam are both. Cellulose is extremely durable and can burn at a high rate. However, it is dusty once it has been installed.

How can you tell if vermiculite insulation has asbestos?

Most vermiculite insulation produced before 1990 used contaminated vermiculite from Libby. The vermiculite asbestos fibers are too small for the naked eye to see. Only a qualified technician can see the asbestos fibers.

Does cellulose insulation burn?

Cellulose insulation is typically burned in an attic space, or inside a wall. It burns at such low temperatures, that even the most powerful thermal imaging camera (TIC), may not be able to pick up any heat. The smell of burning paper is a sign that there is a fire in the cellulose.

When did asbestos stop being used in insulation?

In 1973, EPA banned spray-applied surfacing asbestos-containing material for fireproofing/insulating purposes.

Would a house built in 1950 have asbestos?

Asbestos insulation could be found in houses built between 1930 and 1950. It is possible to find asbestos in wall and ceiling joint patching compounds and textured paint. In 1977, its use was prohibited.

Would a house built in 1890 have asbestos?

These roofs are not uncommon but can be expensive. These houses are likely to have lead paint. They may also contain asbestos. Asbestos is usually found in basement heating pipes. If necessary, it is important to take appropriate precautions and have the asbestos removed or remedied.

How much exposure to asbestos will cause mesothelioma?

2% to 10% of people are the most likely to develop pleural cancer after prolonged, heavy asbestos exposure. The symptoms of mesothelioma typically do not manifest until approximately 20-50 years after exposure to asbestos. This is because tumors have spread and grown.

Can you get mesothelioma from one exposure?

If the amount of asbestos particles lodged in the tissues is significant, it’s possible to get mesothelioma or pleural effusions after one-time asbestos exposure.
