Our main activity is applying of innovative and effective solutions for reduction of noise and vibration in public and industrial rooms and in the machinery. Noise reduction in the civil and industry buildings with the cellulose based material SonaSpray (ICC – International Cellulose Corporation). The SonaSpray technology is used for the reduction of the reverberation time in the rooms as well as for the overall noise reduction in the buildings like: sport halls, swimming pools, convention and congress centers, koncert halls, cinemas, theatres, office rooms, underground garages, technical and factory rooms, etc. The cellulose material with a special glue material is sprayed on ceilings and walls and is very effective regarding the noise absorbtion and is competitive concerning the price in comparison with other sound insulation materials. We perform projects in the area of room acoustics and evaluations regarding acoustics requirments. We offer also soundisolation materials.
