5. 3. 1. Avoiding inorganic fibres in indoor air


description relevant product categories 

explanation

According to the WHO, fibres that are longer than 5 µm, have a diameter under 3 µm and an aspect ratio greater than 3:1 are regarded as respirable fibres. The maximum length of such fibres is around 100 µm. Fibres that meet these criteria are referred to as WHO fibres and may enter the lung. They are particularly critical from a toxicological point of view and thus should not be emitted into indoor air.

 
minimum requirement

Mineral wool insulation that faces the interior must be installed with a fibre-tight sealing in order to prevent fibres, especially WHO-fibres, from subsequently being released into indoor air.
