How to tell the difference between cellulose and asbestos insulation
Answer:
If you have loose-fill insulation that is gray, soft, and without a shine, it is probably cellulose insulation. Cellulose contains a high percentage of recycled paper and does not contain minerals. In general, it looks like shredded gray paper.
The differences is in the ingredients, they do look very similar when they are inspected. Although it is a different insulator, there are similar issues with vermiculite attic insulation as it is a very difficult proposition to see whether asbestos is contained within. The best thing to do is not to touch it but obtain the services of a professional to extract some samples and get a confirmation as to whether it contains asbestos. If asbestos is contained, you will want to seriously consider instituting a program of asbestos management or to completely remove the asbestos.
Asbestos has a higher heat resistance and tensile strength properties when compared to fiberglass. Fiberglass is more temperature resistant than polyamide and cotton, but it isn’t comparable to asbestos in this regard.
We recommend getting a sample tested, read more about here: Testing for asbestos.
The results of testing can provide peace of mind, by confirming whether the building material actually contains asbestos or not. If the results of asbestos testing confirm that the material does not contain asbestos, this will help reduce the cost of your planned renovation or demolition. If the results confirm the material does contain asbestos then we suggest you engage an asbestos removalist.
What Does Asbestos Insulation Look Like?
When it comes to asbestos, it rarely needs introduced at this point. The majority of homeowners need to be educated on the general danger of breathing and disturbing asbestos fiber. Older buildings and homes may have asbestos within products from hot water piping insulation to furnace insulation, even floor tiles. Typically, it is recommended to simply leave it as-is without disturbing it. Otherwise, hire a professional asbestos removal company.
However, there are loose-fill wall and attic insulation which can contain asbestos. If you’re insulation is the batt style insulation, as the loose fill insulation has the higher risk as it’s loosely poured into wall or joist cavities. You may also find thousands of loose particles within walls or under attic flooring. These are the insulation types that pose the most risk.
So, how do you identify if your attic insulation contains asbestos? Below we will discuss specifics about loose fill insulation which could contain asbestos.
