Pyramidal sound insulation based on polyurethane foam
Polyurethane foam is the most efficient, most popular and economical material for sound absorption.
Basic technical characteristics:
The main features of sound absorption material are their cellular properties and porosity. When a sound is heard with a material that has a cellular structure, it will absorb a large part of the sound wave. Absorption polyurethane panels of 35 kg / m3 density, open cell structures. They are suitable for their characteristics and easy installation for industrial use, for insulation of motor spaces, compressors, air conditioning and ventilation, music, TV and radio studies, insulation of meeting rooms, theater halls, sports halls, sound insulation of apartments and houses, home cinema , as well as for use in the filling of special acoustic lining. Also, as acoustic isolation of libraries, museums, kindergartens, hospitals, etc. The material is self-extinguishing, easy to process and cut, and in case of need for improved sound insulation properties, it can be used in combination with acoustic membranes in the form of a sandwich panel.
