What is acoustic glazing ?
Noise pollution is a real challenge in many environments. As a building professional, offering suitable solutions such as acoustic glazing is becoming essential in order to meet ever-increasing sound comfort requirements. This type of glazing improves soundproofing while also meeting thermal, energy and aesthetic insulation criteria.
The advantages of acoustic glazing
for professionals
Meeting the needs of demanding customers
Offering an acoustic glazing ensures optimal sound comfort, whether it is a high-traffic urban area or a space requiring precise sound insulation.
A distinguishing advantage for your projects
Offering acoustic solutions such as acoustic glazing allows you to stand out in a competitive market, while strengthening your position as a specialist in innovative solutions.
Certified technical performance
Certified technical performance. The acoustic glazing meets strict standards (Rw ratings, AR1 to AR6 certifications), allowing you to deliver measurable results to your clients. The higher the Rw rating, the more effective the sound insulation:
Rw 30-35 dB: Ideal for moderately noisy environments (residential areas).
Rw > 40 dB : Perfect for high-noise areas
(roads, stations, airports).
(roads, stations, airports).
Adaptability to thermal constraints
In addition to acoustic insulation, these glazing solutions can be combined with high-performance thermal insulation (optimized U-value), helping to reduce energy costs for your clients while meeting the requirements of RT 2020 and RE 2020 standards.
Easy to integrate into your projects
The acoustic glazing can be integrated into new constructions or existing structures without compromising aesthetics. Double and triple glazing solutions adapt to different types of frames and configurations.
Did you know ?
For the ear, a decrease in :
1 dB is almost inaudible ;
3 dB is barely perceptible ;
5 dB is significant ;
10 dB corresponds to a halving of the perceived sound intensity ;
20 dB corresponds to a three-quarter decrease in the perception of sound intensity ;

everything you need to know
To help you choose and offer the best solution for your customers, here are the key features of the acoustic glazing :
Rw index (sound reduction) :
Rw from 30 to 35 dB : Ideal for moderate environments (residential areas).
Rw > 40 dB : Recommended for highly exposed areas (roads, stations, airports).
Multilayer technology :
Acoustic glazing uses glass of varying thicknesses combined with soundproof resin spacers or insulating gases (argon, krypton) to maximise sound absorption.
Double or triple glazing :
Acoustic double glazing : A versatile solution for most residential and commercial projects.
Triple acoustic glazing : Ideal for spaces requiring enhanced soundproofing (recording studios, hospitals, schools).
Standards and certifications :
Acoustic glazing is rated from AR1 (light attenuation) to AR6 (maximum attenuation). For near-total silence, opt for AR6 glazing (displaying an Rw > 43 dB).
For information, CEKAL also defines acoustic performance classes ranging from AR1 (29 to 31 dB Rw) to AR6 (>43 dB Rw):

Where can acoustic glazing be used ?
Residential
Reduction of external noise pollution, improving living comfort, particularly in urban areas with heavy traffic. Acoustic glazing can reduce traffic noise by up to 50% in highly exposed areas.
Offices and
professional spaces
professional spaces
In open spaces or meeting rooms, acoustic glazing reduces ambient noise, promoting better concentration and improving team productivity. We also manufacture this type of glazing for acoustic booths.
Healthcare sector
For hospitals and clinics, these glazing solutions create a calm environment, essential for patient well-being. An acoustic glazing can reduce external noise by more than 40 dB, ensuring optimal working conditions for medical staff.
Education
Schools and universities benefit from reduced noise pollution to improve the learning environment, with glazing achieving Rw ratings above 40 dB for optimal quietness.
Hospitality and food service
Providing complete peace and quiet in hotel rooms or restaurants enhances the customer experience, particularly in busy areas.

How to choose acoustic glazing
for your projects ?
When choosing acoustic glazing for your projects, here are the key criteria to
consider :
consider :
Sound environment :
Assess the noise level in the immediate vicinity of the building (traffic, neighbourhood, industrial activities).
The noise level should be measured using a sound level meter.

FAQ – Everything you need to know about acoustic glazing
What is acoustic glazing ?
Glazing specially designed to reduce external noise using multi-layered glass and insulating spacers, such as films or gases like argon.
Why incorporate acoustic glazing into your project ?
Whether for urban buildings, offices in noisy areas, or spaces requiring enhanced soundproofing (studios, meeting rooms), acoustic glazing is an effective and sustainable solution to noise issues. Discover its advantages to enhance your projects and guarantee customer satisfaction.
What is the difference between standard glazing and acoustic glazing ?
Standard glazing does not effectively reduce noise. Acoustic glazing blocks noise pollution thanks to advanced technologies (different glass thicknesses, insulating gases).
Can acoustic glazing and thermal insulation be combined ?
Yes, many models combine both features, offering comprehensive solutions for sound and thermal insulation.
What are the ideal environments for installing acoustic glazing ?
Urban areas, offices, schools, hospitals, hotels, as well as spaces requiring maximum soundproofing, such as recording studios.
Is it possible to install acoustic glazing on an existing structure ?
Yes, most modern frames can accommodate this type of glazing, after a preliminary assessment of the structure.
How much does acoustic glazing cost ?
The cost depends on the Rw index, the type of glazing (double or triple), and the dimensions. Expect an average range of €150 to €350/m².
How is the acoustic performance of glass expressed ?
The overall acoustic performance of a glazing is expressed by the sound reduction index Rw (C ; Ctr).
From this overall Rw index, the following can be obtained:
– The “airborne noise” sound reduction index RA, with the formula RA = Rw + C
– The “road traffic noise” sound reduction index RA, tr with the formula RA, tr = Rw + Ctr.
From this overall Rw index, the following can be obtained:
– The “airborne noise” sound reduction index RA, with the formula RA = Rw + C
– The “road traffic noise” sound reduction index RA, tr with the formula RA, tr = Rw + Ctr.
Note: Using argon gas in your acoustic glazing provides an additional sound absorption of about 1 dB.
