Rockfon ® Blanka® dB 46 – Acoustic ceilings

The panels provide improved sound insulation between rooms, as well as high levels of sound absorption where privacy and acoustic comfort are important.
The panels consist of two layers of stone wool, 50 mm thick, with a high-performance membrane between them.

The panels’ deep matte, smooth, and super-white surface offers increased wear resistance, making them more resistant to dirt and daily wear.
A wide range of sizes and edges are available for concealed, semi-concealed, and visible systems.
Lightweight soundproofing panels are easy to install, trim, and clean.

Two layers of stone wool with a high-performance membrane between them.
Face: deep matte, smooth, super-white painted fabric.
Rear: fiberglass.
Durable painted edges.

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.

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.
