Asbestos in old insulating wool?

Even with insulating wool, care was taken early on that this building material is particularly heat-resistant and non-flammable. Therefore, asbestos was sometimes used to make insulating wool resistant. In which insulating wool asbestos could be contained and how it is then disposed of, we show you here at a glance.

Age of insulating wool

Alone at the age of the Dämmwolle is usually not detect whether it is asbestos-containing material or whether the insulating wool is completely safe. In principle, insulation wool produced after 1993 may no longer contain asbestos in Germany. Since then, asbestos in building materials in this country is strictly prohibited. In many products, however, asbestos was no longer used earlier, since the carcinogenic effects of asbestos had already been known since about 1970.

Assessment based on the color

Asbestos itself is gray, something like cement, so asbestos is added to a material that always assumes a grayish tint. Many materials have a brownish-gray hue instead of the distinct gray color. An asbestos-containing material such as insulating wool can never be pure white. For example, you can often use the color of a material to see if asbestos can even be present there. Even high-gloss materials can not contain asbestos.

Suspicion - Special company

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

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

Tips & Tricks

In many private houses, the yellow glass wool was actually processed. The glass wool is not pleasant to dispose of because of its annoying little splinters and you should definitely wear protective clothing, but asbestos contains this material only rarely. You can already see that in the clear yellow color, because asbestos-containing materials are always slightly gray in color.
