Sound absorption is measured in accordance with ISO 354.

Sound absorption data α_(p), α_(w) 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 A_(eq) expressed as m² per item.

#### 󠀁[Other characteristics](https://uzbuild.com/en/rockfon-sonar-acoustic-ceilings/#1584184935129-9b4ee4e2-3786)󠁿

**Fire safety** A1, (EN 13501-1)
 Fire hazard class – KM1 (Federal Law No. 123) (
EN 13501-1)

**Reflection and scattering of light**

light reflection 85%

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

 **Cleaning:** Vacuum cleaner, Soft cloth, Chemical resistance: Resistant to dilute
solutions of ammonia, chlorine, and hydrogen peroxide.

 **Clean rooms** 5

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

 **Environment**  Fully recyclable product

 **Indoor environment** A selection of Rockfon products have been awarded the M1(
Finland) particle emission class for building materials and the Danish Indoor Climate
Label (Denmark) – a symbol for the indoor climate of products with low particle 
emissions.
