Installing a soundproofed door to soundproof a setting is an increasingly common choice, even for residential apartments. Dampening outside noise can come in extremely handy in contexts such as hospitals, medical surgeries, recording studios, offices or schools.
Bertolotto acoustic doors have a certified system that ensures they are soundproofed in accordance with the law.
Why install a sound-insulating door
Soundproofed doors, which are also referred to as acoustic doors or isophonic doors, are a compulsory choice when the sound insulation of a room or of an entire apartment needs to be improved. In many cases, the door is the only point of physical communication between two spaces, and it is precisely the critical area where sounds propagate from one side to the other.
Even if the walls and ceilings are acoustically insulated, if the doors are not sufficiently soundproofed, unwanted sounds automatically make their way to the other side, reducing the acoustic comfort on the inside and also nullifying the work done in to soundproof the other elements.
The need for soundproofing a room is determined by the level of outside noise that is detected inside and the level of noise produced by the room that can be detected outside, with the doors and windows shut.
Acoustic doors are ideal in all rooms where excellent soundproofing is necessary: theatres, cinemas, laboratories, television studios, recording studios, hospitals, libraries, meeting rooms.
Acoustic doors: characteristics
Soundproof doors are windows with strong acoustic insulation , mainly from airborne noise, but they are also very effective against footfall noise.
A normal door provides poor sound insulation, becauseé has a low weight and does not isolate né it absorbs the sound waves that crash on it. The soundproofing characteristics are certified by special bodies , through laboratory tests that ascertain their effectiveness and the level of insulation.
To achieve effective sound insulation, the soundproof doors are made with a robust design and materials such as l’ stainless steel and l’ galvanized steel , which can also guarantee fire resistance. For apartments in areas that are not particularly noisy, soundproof interior doors in wood or PVC can also be installed.
The perimeter seals are also very important, which in an acoustic soundproof door are double or triple.
Bertolotto soundproof doors are hinged and are made with an interior in innovative technical material developed by the R& D department. They have a NO SOUND 50 dB acoustic threshold and certified ACU gasket in high densityà polyurethane foam.

Soundproofed doors are doors with high sound insulation, mainly from airborne noise, but they are also very effective against noise from trampling.
A normal door provides poor sound insulation because it is light in weight and does not insulate or absorb the sound waves that strike it. The sound-insulating characteristics are certified by dedicated bodies by means of laboratory tests that certify their effectiveness and level of insulation.
In order to achieve effective sound insulation, soundproofed doors are made with a robust design and materials such as stainless steel and galvanised steel, which also ensure fire resistance. For apartments in areas that are not particularly noisy, even soundproofed interior doors made of wood or PVC can be installed.
The perimeter seals, which are double or even triple in a soundproof acoustic door, are also very important. Bertolotto soundproofed doors are hinged and are made with an innovative high-tech interior material developed by the R&D department. They have a NO SOUND 50 dB acoustic threshold and ACU certified seal in high-density polyurethane foam.
How to choose a soundproofed door
A soundproofed door should be selected according to the desired level of sound insulation. The RW index defines the sound insulation values of an element and each door has its own. Depending on the intended use, you can choose the type of soundproofed door to be installed in a given place. Bertolotto acoustic doors are made to enable a certified ACU RW 35 dB abatement according to UNI EN ISO 10140-2-UNI EN ISO 71 standards.
It is always a good idea to get expert advice on which of the acoustic doors to install. For healthcare facilities, clinics, medical surgeries, you will need to install a door that guarantees privacy but also ease of cleaning and sanitising, so opt for an aluminium door. In elegant settings, featuring a minimalist and understated design, you would be better off opting for a soundproofed flush-fitting door or one with a sophisticated finish.
Bertolotto soundproofed doors can be customised with a wide range of finishes and colours, to suit any surroundings and match existing doors already fitted. The acoustic door can be further customised in its accessories, including a lock and key, a special handle or an automatic door closer.
