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.

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.

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.
