Acoustical Test Data:

We carried our testing at 2 recognized laboratories in the world; in Europe the Fraunhofer Institut in Stuttgart and in the U.S.A. the famous Riverbank Acoustical Laboratories in Illinois.

Fire Test Data:

Sonacoustic was tested on fire resistance, in Europe as well as in the U.S.A. Both certified laboratories rated Sonacoustic as incombustible.

  • Firelabs, Berlin-Germany. Classification A2-s1,d0 according to EN 13501-1
  • Intertek –Elmendorf – Texas. Sonacoustic was tested according to ASTM E84-11a Test for Surface burning – Characteristics of Building Materials (UL 723, UBC 8 – 1, NFPA 255) Test result:
    Flame spread index 0
    Smoke developed index 0

Fungi Resistance;

Sonacoustic was tested on “ Fungi resistance “ according to ASTM C 1338 by R & D in Cookeville – Tennessee – U.S.A., result: no fungal growth appeared.

Thermal properties;

Thermal conductivity and water vapor transmission were tested by MPVA laboratories in Neuwied – Germany.

Health;

No carcinogens and reproductive/developmental toxins could be detected. Classified M 1 by Eurofins laboratories in Denmark – test reports G09415A & G09415C.

Light reflectance;

Tested by Chemir laboratories according to ASTM E1331.
Result: a very high average light reflectance value of 94,69 for the standard white color.
