What are acoustic doors?

These doors are designed to reduce the spread of noise and vibrations between rooms. They aim to insulate the sound within a room, which is achievable thanks to insulation engineering within the body of the door.

Acoustic doors act as a barrier that restrict the reflection of sound.

The materials with the optimum sound-proofing insulating qualities that reflect and absorb sound include:

  • Steel
  • Timber
  • Aluminium
  • PVC

By theory, the greater the mass of the door and the more solid it is, the less sound transmission. However, this can be improved through the use of insulating foam or the sandwiching of dense cores.

You can get single and or double acoustic doorsets, depending on your needs. For example, cinemas and theatres often use double doorsets to provide better soundproofing. To find out more about soundproof doors and decibel ratings, head here.

Acoustic doors and doorsets can include hinges, frames, and ironmongery. The doors are also available in veneer or painted finishes and can be designed to fit your unique needs. Proving that acoustic doors don’t have to be ugly!

How are they produced?

They’re created from a solid core material that insulates and creates a barrier against sound. The core of these doors often contain insulating foam or a reinforced core.

They also use an acoustic seal. Like an intumescent seal, they work to create an airtight seal around the door to prevent any sound transmission. The acoustic seal also holds an acoustic or decibel rating.

And let’s not forget that acoustic doors can also be fire-rated too! Protecting against fire and sound, they are multi-functional and have the potential to both save and improve lives.

Main Components:

  • Door core
  • Door leaf
  • Door frame
  • Hinges
  • lock
  • Acoustic seal

Types of acoustic seals:

  • Batwing: An L-shaped seal fitted to the surface of the door frame and the door stop; so, the edge of the door will meet the seal upon closure.
  • Drop: A straight seal, fitted to the bottom of a door, which drops down automatically when the door closes to form a firm seal.
Internal Acoustic Doors

Where can acoustic doors be used?

They are used in many places, especially where there is a need for privacy or in environments with extreme noise. For example:

  • Music or Broadcasting Studios
  • Healthcare environments (doctors’ surgeries or hospitals)
  • Schools and Universities
  • Legal environments (courts or police stations)
  • Businesses
  • Blocks of flats
  • Factories, building sites and laboratories

When noise pollution becomes a concern to safety or a threat to wellbeing or confidentiality, you need to start considering acoustic doors as an option. If you want to discuss whether you may need one, just send us a message at info@vigordoors.com, call us on 01642 265034 or visit us at our showroom.

Are they required?

There are building regulations surrounding the standard for soundproofing in domestic and commercial buildings, in terms of sound insulating walls and floors to reduce noise from adjoining buildings and internal sound transmission in the home. These regulations aim to cut out normal levels of sound such as: speech, TV and music playing.

They are not a legal requirement, but they do aim to improve soundproofing when ordinary door or standard building sound insulation will not be enough to reduce excessive sound.

The Benefits:

Health & well-being:

Loud and constant noises can cause a lot of disruption, contributing to stress. Using an acoustic door to reduce or stop excessive and unnecessary noise can help you to feel calmer, improve concentration and gain a better sleep. Additional insulation and seals can also reduce the spread of dust, smoke, and draughts.

Improvement in audio recording/listening:

In music studios, broadcasting stations or cinemas, they can help improve the quality of sound, whether that be the recording or playing. By preventing any unwanted sound from disturbing the experience, they also aid in keeping the sound in the recording or insulated room. This will improve the overall sound quality.


Not only do they block sound from entering but also help with-hold sounds inside spaces too. In environments such as doctors, hospitals, and business offices, this allows for excellence standards of privacy and confidentiality, as sound such as telephone calls and meetings cannot be overheard.


Loud sounds can be extremely dangerous, with any sound above 85 dB potentially causing hearing loss. In environments like factories, in which machinery can cause above average or damaging sound, decibel-rated acoustic doors can help to separate areas with loud sound from other spaces and act as a level of protection for hearing.

Decibel Ratings

The amount of sound the doors can block and their effectiveness are tested and rated. This is what makes each acoustic door individual, as stronger solid-core can withstand and reduce larger and stronger sounds.

The strength of sound is measured in decibels. All doors have different decibel ratings. The rating usually appears like so: 30dB. This means the door can block up to 30 decibels.

At Vigor Doors, we manufacture doors of all decibel ratings, even up to as much as 45dB. The higher the decibel rating, the thicker the door core.

The decibel rating will differ depending on the type of sound, building and intensity it may need to contend with. For example, cinemas often have the highest offered decibel rating.

There are two versions available:

  • High-performance: noise reduction value of 44dB
  • Low/ medium performance: noise reduction value of 34dB

The type you need will differ depending on the functionality.
