Soundproof doors

Steel rolling soundproof doors are almost visually indistinguishable from typical industrial rolling or sectional doors. However, they feature a special design and different profile filling that dampens sound, as well as coatings and tracks that absorb noise. When equipped with the appropriate sealing systems for the tracks and lintel, the doors achieve satisfactory sound insulation performance.

In addition to steel doors, NGR Technologie also offers lightweight, flexible fire-resistant doors made to the EI 120 class, with enhanced acoustic insulation properties.

Soundproof doors are always selected based on the type and individually designed, taking into account the specific requirements of the given project. This applies both to the acoustic insulation parameters and the installation conditions for a specific opening, as well as the fire resistance class.
