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-blanka-db-46-acoustic-ceilings/#1584184935129-9b4ee4e2-3786)󠁿

**Interior sound insulation** Dn,f,w = 46

**Direct sound insulation** Rw = 25

**Fire safety** A2-s1,d0, (EN 13501-1) Fire hazard class – KM2 (Federal Law No. 
123) (EN 13501-1)

**Reflection and scattering of light** light reflection 87% light scattering >99%

**Panel Appearance:** Super White Surface Whiteness (L): 94.5. Deep matt surface,
ideal for critical side lighting. Gloss: gloss level 0.8 at 85°. The panel's whiteness(
L) is tested according to ISO 7724 and measured on a scale from 1 (black) to 100(
white). Panel gloss is measured according to ISO 2813.

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

 **Surface durability**

Increased strength and dirt resistance

 **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

 **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.
