Soundproof Doors

Soundproof door

To insulate a room acoustically and cut out noise coming from outside as well as from inside, the most effective solution is the soundproof door, also known as an acoustic door or noise-reducing door depending on where it is used. Doors with a high level of sound insulation dampen the vibrations and mechanical waves of sound, in particular those between 50 Hz and 5,000 Hz, from the lowest tones to the highest.

Acoustic internal doors can raise the overall quality of a hotel or guest house, because the sound insulation of the rooms is often the weak point. The most common mistake when designing a hospitality building is to concentrate on the furniture, the layout and other aesthetic parameters, while forgetting that comfort also depends on proper sound insulation between the room and the corridor. Staying in a noisy hotel is an unpleasant experience, and one that ends up damaging the reputation of the whole property.

Acoustic doors: how to read the dB rating

The decibel (dB) is the unit that measures the acoustic performance of a sound-insulating door: the higher the value, the more the door blocks the passage of noise. Our catalogue offers soundproof doors from 28 to 50 dB, each designed for a different need:

- 28-32 dB: basic insulation, ideal for homes or offices where voices and everyday noise need to be reduced, with no extreme requirements.

- 36-42 dB: the middle of the range, and the most requested for hotel rooms, guest houses and offices facing corridors or noisy common areas.

- 50 dB: the top of the range. Maximum acoustic resistance, suited to technical rooms such as recording studios, rehearsal rooms, theatres or cinemas, where even the smallest leak of sound spoils the result.

A noise-reducing door with a higher dB rating generally means a thicker panel and a more complex system of seals: the 50 dB models are therefore distinctly technical products, while the 30 dB door remains the most balanced compromise between performance and budget.

For those who also want a flush-to-wall design, the flush line reaches up to 41 dB of sound insulation, combining minimal looks with figures suited to demanding settings.

Features and advantages of acoustic doors

Our soundproof doors are not simply a heavier panel: acoustic performance comes from the whole set of components that seal the perimeter of the door.

- Sound-insulating panel: the heart of the door, built from multiple layers that block the transmission of sound without making the leaf excessively heavy.

- Perimeter seals: applied on every side of the door, they stop noise filtering through the gaps between leaf and frame.

- Drop-down threshold seal: it lowers automatically on closing and seals the bottom of the door, the most critical point for acoustic leakage.

- Locking system: cylinder and lock designed to keep leaf and jamb constantly in contact, so that the acoustic seal does not weaken with use.

These design choices make the FIP Porte acoustic door a certified, reliable solution — not a standard door with an adaptation bolted on.

Where to install noise-reducing doors

The applications of soundproof doors cover very different settings, each with its own acoustic requirement:

- Hotels and guest houses: insulating rooms from corridors, common areas and adjoining rooms is decisive for the quality of the stay as guests perceive it.

- Offices: meeting rooms, professional practices and workstations where conversations must remain confidential.

- Homes: acoustic internal doors make it possible to separate the sleeping area from the living area, or to insulate a room used for music, home cinema or remote working.

- Technical rooms: recording studios, rehearsal rooms and screening rooms, where the highest available level of sound absorption is needed.
