Acoustic glazing (Acotherm AC2–AC4 or CEKAL AR2–AR6 label) offers a reduction of 28 to 40 dB , compared to 25–32 dB for standard double glazing, guaranteeing perceptible silence from 3 dB of actual reduction.

In a noisy urban environment (traffic, construction sites, public transport), single glazing filters little sound, and conventional double glazing limits its reduction to around 32 dB. Acoustic glazing significantly improves this performance thanks to special spacers and glass of different thicknesses. At YES GLASS , discover how soundproof glazing combines comfort, security and energy savings for your apartments, offices or hotels.

What is acoustic glazing?

Acoustic glazing is double or triple glazing which includes:

• An acoustic laminated PVB interlayer that absorbs sound waves.
• Asymmetrical glasses of two different thicknesses to disrupt and reduce sound transmission.

These technologies increase the sound reduction index (Rw) measured in decibels (dB), well beyond what traditional glazing allows.

Standards and labels

• CEKAL AR : AR1 (≤ 25 dB) up to AR6 (> 37 dB)
• Acotherm : Ac1 (28 dB) to Ac4 (40 dB)
• NF EN 12758 for acoustic laminated glazing

Comparative performance

Type of glazing	Attenuation Rw (dB)
Single glazing	≤ 25
Standard double glazing (4/16/4)	28–32
Double soundproof glazing	33–38
Triple acoustic glazing	38–44

Each 3 dB decrease results in a halving of the perceived sound energy, for an already very perceptible silence.

Benefits for your comfort and savings

• Reduced stress and improved concentration in offices
• Better quality sleep in rooms exposed to urban noise
• Thermal performance Ug ≈ 1.1 W/m²·K , identical to high-performance double glazing, for heating savings
• Enhanced security : laminated glass stays in place in the event of breakage, protecting against falling glass and break-in attempts

When to choose acoustic glazing?

• Very noisy areas (roads, stations, airports): AR5/Ac4 minimum
• Hotel rooms or offices in the city center : AR3/Ac2 to AR4/Ac3 depending on the level of nuisance
• Exposed living areas (living room, home office) to combine silence and thermal performance

Conclusion

Investing in acoustic glazing is the most effective solution for restoring indoor calm while maintaining the thermal insulation of your windows.
