How to tell the difference between cellulose and asbestos insulation?

Asbestos was still used in various fire retardants and as an insulator until the 1980s. It was versatile and affordable. You could use it in tiles or blow it with vermiculite.

Differences Between Asbestos And Cellulose Insulation

Before we discuss the differences between asbestos insulation and cellulose insulation, it is worth understanding the properties of each material.

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 if the walls are not damaged or have no cavities that expose asbestos fibres. It can pose a serious health risk if asbestos particles are released into the air and reach your property.

Cellulose Insulation

Cellulose insulation can be used as an alternative to asbestos. It is made from many materials, including paper, straw, cardboard, and hemp. Boric acid is used to treat a paper-based mix of cellulose. This gives it fire resistance properties.

Dry cellulose, also known 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.

Cellulose works in pipes, walls, and around wiring, just like asbestos. It can be used to suppress fires or insulation your home. Cellulose can also be recycled, which is an advantage for those who want to make their buildings more green.

There are differences

Now you know the differences between the ingredients. However, they look very similar when inspected. It is a 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 samples to confirm whether or not it contains asbestos. You should seriously consider whether to implement a program for asbestos management or completely remove asbestos.

What should you do next?

If you have more than 10 square feet of asbestos, you will need professional help. 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 spreading, reverse airflow will be used. The asbestos will be removed using special protective equipment.
