Acoustic Doors

The weakest links for noise leakage are the entry and exit openings, through which a noisy air flow passes .

HNA offers a variety of doors designed to reduce noise entering rooms.
Our doors are made of galvanized metal and are painted in any epoxy colour.

We produce two levels of acoustic doors. Main noise reduction levels Are 40 and 50 DB (a) based on the acoustic demand. It is possible to deliver the doors with a variety of locking mechanisms and door frames including: Alarm mechanisms, windows and glass openings, designed metalwork and colours in any shade of your choice.
Each door is manufactured based on the customers specifications and in any size ensuring an excellent acoustic level reduction.

Applications:
Doors are suitable for many uses such as: generator rooms, machine rooms, factories, recording studios, audiometric cells, medical institutions, cinemas, theatres, concert halls, sports halls, libraries, hotels, and more.

Technical advisor:
Our engineers provide advice and assistance to customers apon request and are happy to work with architects, contractors and engineers on the aspects of noise control to ensure all specifications are met.
Noise testing may be performed before and after installation, on-demand.

Materials:
Our doors are built from galvanized steel and noise absorbing materials. We include high quality engraved steel hinges. Hinges are designed to ensure durability and longevity.

Sealing:
We seal our doors with unique rubber seals or magnetic seals. The degree of insulation varies according to the level of noise reduction as well as the lower threshold of the door.
