Sound insulation doors

Teckentrup sound insulation doors

Teckentrup sound insulation doors are available in single-leaf and double-leaf variants. The door elements consist of a movable door leaf and a fixed frame, also commonly known as the doorframe. The Frame covers the wall opening on one hand, and on the other serves to take in the hinges as well as the locking plate where the lock latch clips into place. Frames can be made from very different materials. Steel frames in particular are used in frequently used areas due to their high stability and robustness.

Sound insulation doors inside

Whether it’s an office, a public building, or a home: sound insulation has a significant influence on the health and well-being of people. Noise and loud noises in the workplace influence the “work environment” and also limit the ability to concentrate and absorb information. People need peace and quiet for optimal work performance, a feeling of well-being and healthy sleep. A standard door is only capable of swallow-ing the noise that comes from the hall or other rooms in a limited fashion. Which is why we offer the sound insulation door. 
The Teckentrup sound insulation door can be used inside and outside. With a sound-insulating door, two functions can be performed at once: on one hand, they insulate noise coming from the inside to the outside, such as rooms with high noise levels. On the other hand, they can keep the noise outside, for instance in residential or office buildings.

The thickly insulated door leaf of a sound insulation door is designed to provide optimal sound insulation using special seals. Depending on the configuration, Teckentrup sound insulation doors tested in accordance with DIN EN 20140/717-1 achieve excellent sound insulation values of up to 57 dB (decibels).

Areas our sound insulation doors are used:

  • All industrial Areas
  • Commercial premises
  • Event spaces
  • Conference rooms
  • Public buildings
  • Residential housing

Sound insulation doors provide protection against high noise Levels

Workspace sections with a high noise level must be separated from office spaces and rooms with lower levels of noise, especially within the course of everyday business. Teckentrup sound insulation doors are used here. To protect against high noise levels, Teckentrup's steel sound-proof doors offer optimum sound insulation. They ensure pleasant acoustics, reduce noise pollution, increase work efficiency and protect health. The precise interplay between door leaf, frame, fittings and floor joint guarantees efficient noise protection. The doors provide very good noise insulation up to 57 dB thanks to the particular construction of the door leaves, the very thick insulation material and the special seals.

High insulation values are necessary in buildings with large levels of noise, in particular, such as testing spaces for motors or turbines. Sound waves can penetrate through even the smallest of openings. This also means that the sound insulation door must be sealed optimally. Special seals ensure that the gap between the door leaf and frame when the door is closed is really sealed. The seal of the sound insulation door with the floor is created using special floor seals that have a sound-insulating effect here. This is usually accomplished via a retractable bottom seal that automatically sinks down when the door is closed. In addition, a slide or buffer seal can be used.

Hotel Radisson Red Cape Town

Radisson Red, Cape Town

Tourism booms worldwide, especially in popular destinations. New hotels spring up everywhere like mushrooms! This can be seen on the other side of the world too: in Cape Town, at the thrilling port metropolis at the foot of Table Mountain, the Rezidor Hotel Group opened, under the new “Radisson Red” label, a high-profile 4-star hotel with a modern interior.
Elbe Philharmonic Hall

Elbe Philharmonic Hall

In a building such as the Elbe Philharmonic Hall first-class products are not only installed where they are visible and aesthetics matters but everywhere. In a concert hall with an auditorium capacity of up to 2.100 spectators the escape routes for instance require time-consuming planning. In such a superlative building interior design in every detail counts. Thus the doors are chosen due to their functionality and due to their aesthetic criteria: Fire protection and smoke protection have to be harmonised with the creative claim of a flush view.
Colditz Castle

Colditz Castle

The recently renovated 'schloss Colditz' in Saxony, Germany is a great example of how to reconcile the often conflicting demands of historic preservation and fire-protection. For example, many of the passageways have been fitted with the Teckentrup T30 all-glass doors, which combine functionality with aesthetics and maximum transparency.
