High Sound Attenuation
Noise Reducing Acoustic Louvres
ALARA’s ventilation grilles are suitable for a variety of (business) applications in, for example, construction and industry. Each market has specific requirements and guidelines, which we apply to the grilles in, for example, material, certified filling, required air flow. We have both standard and customized solutions.
Advantages of sound attenuating acoustic louvres from ALARA:
For Every Situation
ALARA supplies customer-specific acoustic louvres for both the industrial sector and residential construction. Every grille is produced entirely to size and can be finished in any color. In addition to size and color, we naturally tailor our solutions to your desired sound attenuation level. In this way, we always offer a suitable product to match any architectural vision. For projects where a very high attenuation value is required, we can also supply sound absorbers if required.

Frequently asked questions
Noise Reducing Acoustic Louvres are ventilation grilles that combines airflow with noise reduction. It is used when installations require ventilation while noise escaping through air openings needs to be kept to a minimum. a ventilation grille that combines airflow with noise reduction. It is used when installations require ventilation while noise escaping through air openings needs to be kept to a minimum.
At ALARA, acoustic grilles are fully tailored to both the airflow requirements and the desired acoustic performance of the project.
Noise Reducing Acoustic Louvres are ideal when a technical installation requires sufficient air intake or exhaust while simultaneously having to comply with strict noise limits.
Common applications include:
- Industrial buildings
- Generator enclosures
- Technical buildings
- Data centers
- Power plants
- Machine rooms
- Ventilation installations
Noise Reducing Acoustic Louvres allow air to pass through while internal acoustic materials and specially designed blades absorb or deflect sound.
This maintains ventilation capacity while significantly reducing noise emissions.
The final noise reduction depends on:
- Airflow rate
- Dimensions of the grille
- Noise frequency
- Available space
- Required performance
ALARA performs technical calculations in advance to optimize the grille for the installation.
Yes. Many grilles are used in outdoor installations. They can therefore be manufactured using:
- Corrosion-resistant materials
- Weather-resistant coatings
- UV-resistant finishes
- Water-draining constructions
This ensures reliable long-term performance.
Yes. Every application requires a different combination of airflow capacity, dimensions, and noise reduction.
ALARA therefore designs custom grilles that perfectly match:
- Airflow
- Available space
- Façade construction
- Technical installation
- Required acoustic performance
Yes. In addition to technical performance, the appearance of a building can also play an important role. Grilles can therefore be supplied in different:
- Dimensions
- Colors
- Blade designs
- Finishes
This allows them to integrate with both industrial and architectural projects.
Yes. ALARA acoustic doors are designed for long-term use in demanding industrial environments.
Depending on the application, the design takes into account:
- Heavy mechanical loads
- High frequency of use
- Moisture
- Dust
- Chemical exposure
- Corrosion
Yes. Acoustic grilles are often combined with:
- Ventilation sets
- Sound enclosures
- Custom containers
- Acoustic walls
- Silencers
- Technical buildings
This creates an integrated ventilation and noise-control concept.
The design begins with an analysis of the required airflow capacity, noise source, and desired performance.
The following factors are then considered:
- Airflow
- Pressure drop
- Ventilation requirements
- Noise reduction
- Available space
- Weather conditions
Based on these factors, ALARA develops a grille that integrates optimally with the application.
Noise Reducing Acoustic Louvres need to do more than simply allow air to pass through. It must contribute to the overall performance of the installation. By combining expertise in ventilation technology, acoustics, and engineering, ALARA develops custom grilles that provide:
- Optimal air supply
- Minimal noise emissions
- Low pressure losses
- Durable performance
- Easy integration
- Long service life
This makes the grilles an important component of a complete acoustic solution.
