High performance soundproof doors
Up to -55 dB !
Heinen doors are the preferred option for acoustics specialists owing to their impressive acoustic test results (up to -55 dB!).
Confidentiality, respect for privacy and working conditions are all factors that today require us to create an environment where noise pollution must be reduced. The aims are to
- to improve the company’s image,
- to reduce illnesses caused by a noisy environment,
- improve the attractiveness of the workplace.
Acoustic doors
This is why Heinen has put its expertise at the service of its customers such as leisure centres, telecommunications, theatres, industry, test centres, etc. Our customers demand truly acoustic doors, but which retain their aesthetic qualities and are easy to use.
With this in mind, Heinen has developed its famous 7cm thick doors, with extra-flat or retractable thresholds to allow heavy traffic to pass through easily and conveniently.
Heinen has also ensured that the acoustic properties of its doors can be combined with other features (fire resistant, burglary resistant, etc.).
The performance of the Heinen acoustic door
Heinen Doors offers a range of high-performance doors in terms of both security and acoustics. From fire resistant doors to burglary resistant doors, each model is designed to meet the most stringent security requirements and can offer excellent acoustic performance on request.
Heinen doors are available with impressive sound reduction levels, up to 55 dB (-2 to -7) in the single version and up to 53 (-2, -8 dB) in the double version. This unique combination makes it possible to meet specific needs in demanding environments such as concert halls, museums, or TV and film studios, where sound insulation is crucial to preserving an optimal atmosphere.
Thanks to this attenuation capacity, Heinen doors provide protection against unwanted noise while maintaining a high level of security, whether in terms of fire resistance or tamper-proofing. This versatility makes Heinen doors an ideal solution for projects where security and quality acoustics need to be optimised simultaneously.

Doors with optional and cumulative performances
In addition to their length of protection and particularly wide range of sizes, Heinen doors can combine performance ‘à la carte’. Depending on your needs, one or more performances can be added to the basic METAL+ door.

FAQs soundproof & sound-insulating doors
An acoustic soundproof door is a certified doorset engineered to reduce noise transmission between compartments. Unlike standard commercial doors, Heinen sound-insulating doors deliver certified sound reduction up to 55 dB for single-leaf doors and 53 dB for double-leaf doors under standard EN 717. Designed for intensive use in demanding environments like industrial facilities, telecommunications, theatres, test centres, and TV or film studios, they combine sound attenuation with heavy-duty structural stability.
Soundproof doors work by utilising mass, damping, and precision sealing to block sound transmission. Heinen takes this further with the Metal+ Inside design: a rigid, mechanically assembled steel structure filled with high-density acoustic materials. The critical “weak points”, the gaps between the leaf and frame, are eliminated through specialised perimeter seals and retractable or extra-flat thresholds. This ensures a perfect airtight seal that maintains its acoustic integrity even after hundreds of thousands of openings, backed by a unique 10 to 15-year warranty (depending on the installation method).
Heinen industrial soundproof doors are constructed around the Metal+ steel framework. Available in single-leaf, double-leaf, XXL hinged, surface-mounted, or hatch configurations, the 7 cm thick steel door leaf utilises high-density acoustic cores, perimeter sealing, and mortared or bolted frames to deliver high-performance sound insulation.
Yes. Built on the modular Metal+ base structure, Heinen soundproof doors offer cumulative “à la carte” performance. You can combine high sound insulation (up to 55 dB) with fire resistance, smoke tightness, burglary resistance, anti-panic hardware, bulletproof protection, thermal insulation, and intensive-use durability on a single certified doorset.
Standard industrial soundproof doors often require raised bottom thresholds that create tripping hazards or block machinery. Heinen solves this by equipping its 7 cm thick steel doors with specialised extra-flat or retractable thresholds. These thresholds maintain a tight acoustic seal (up to 55 dB) while allowing smooth, convenient passage for heavy traffic, carts, and equipment in commercial soundproof door applications.
Heinen doors are engineered for extreme durability, with a life expectancy of over 25 to 35 years even in high-traffic environments. We offer a unique warranty based on the installation method: a 15-year warranty for doors installed with welded clamps and mortar filling, and a 10-year warranty for screwed installations. This ensures that the acoustic seals and mechanical integrity remain high-performing through hundreds of thousands of cycles.
The cost of a Heinen industrial soundproof door varies widely based on specific project requirements. Pricing depends primarily on the required sound insulation rating (up to 55 dB), door dimensions (width and height), leaf configuration (single-leaf or double-leaf), and cumulative performance combinations (such as fire or burglary resistance).
