Effective door sound insulation with soniflex - silence begins at the door
Door sound insulation with soniflex - less noise, more silence
Noise can have a significant impact on quality of life - whether you're working from home, sleeping or relaxing. One of the most common weak points in sound insulation is the door. Particularly in homes, offices, doctors' surgeries or recording studios, leaking or thin doors can allow unwanted noise to penetrate - or confidential conversations to leak out. Door sound insulation from soniflex offers a targeted and effective solution here: quick to install, highly effective and visually appealing.
Why door sound insulation is so important
While ceilings, floors and walls are often fitted with soundproofing measures, the door often goes unnoticed - even though it can act as a so-called sound bridge. Due to its comparatively low mass, it offers hardly any resistance to sound waves. Doors also have gaps and openings through which sound can easily penetrate.With an additional sound insulation solution, noise pollution can be significantly reduced and room comfort noticeably improved. Targeted door sound insulation:
✔ Reduces disturbing noises from outside
✔ Improves the room acoustics
✔ Increases privacy
✔ Increases the sense of well-being
Tip
If the gap between the door leaf and the floor is too large, we recommend using a door broom or a door floor seal. Optimum sound insulation can only be achieved if all joints and openings around the door are completely sealed.
