Noise resistant doors

 

We offer soundproof doors produced using technology that ensures airborne sound insulation index Rw≥40 dB. It is possible to order doors with lower airborne sound insulation indexes Rw (28dB - 39dB). Production suitability to standard LVS EN ISO 717-1:2000/AI:2006 is monitored by AS Inspecta Latvia. Noise resistant doors are mostly produced for concert halls, theaters and music schools as well as for other education institutions.
