Sound absorption is measured in accordance with ISO 354.

Sound absorption data αp, αw and absorption class are calculated in accordance with ISO 11654. Sound absorption properties of islands and baffles are quantified by the equivalent sound absorption area Aeq expressed as m² per item.

Fire safety   EN 13501-1

Fire safety Fire hazard class – KM1 (Federal Law No. 123)

Reflection and scattering of light 86%

Moisture resistance Up to 100% relative humidity.
No visible sagging at high humidity.

Cleaning Vacuum cleaner, soft cloth

Hygiene Stone wool has no nutritional value, therefore it does not support the development of harmful microorganisms.

Environment  Fully recyclable product
