Is the asbestos insulation colored

Asbestos in old insulation wool?

Age of the insulation wool

The age of the insulation wool alone cannot usually tell whether it is a material containing asbestos or whether the insulation wool is completely harmless. In principle, insulating wool produced after 1993 may no longer contain asbestos in Germany. Since then, asbestos has been strictly forbidden in building materials in this country. In many products, however, asbestos was no longer used earlier, as the carcinogenic effects of asbestos had been known since around 1970.

Assessment based on color

Asbestos itself is gray, somewhat like cement, so if asbestos is added to a material, it always takes on a grayish tint. Instead of a distinct gray color, many materials have a brownish-gray color. A material containing asbestos such as insulating wool can never be pure white. You can often tell from the color of a material whether it can contain asbestos at all. Even high-gloss materials cannot contain asbestos.

Suspicion - specialist company

If you suspect that the insulation materials you want to dispose of contain asbestos, a specialist company must take a sample. This is then tested for components of asbestos in a special testing institute.

If the suspicion of asbestos is proven, the specialist company must properly dispose of your insulating wool. However, if this is not the case, you can dispose of it yourself. Then the insulation wool simply belongs to the construction waste and has to be sorted on a landfill. In any case, you will have a written confirmation that this material is harmless. Because without this confirmation, no landfill will accept these possibly asbestos-containing materials from a private person.

In a lot of private single-family houses, the yellow “glass wool” was actually used. The glass wool is not pleasant to dispose of because of its annoying small splinters and you should definitely wear protective clothing, but asbestos rarely contains this material. You can already see this from the clear yellow color, because asbestos-containing materials are always a little gray in color.
