How Much Quieter Could It Be?
It depends on two things: the noise you are dealing with, and the glass you put in front of it. ToughGlaze acoustic laminated glass is certified from Rw 36 dB (TG 11.5 TALG) to Rw 39 dB (TG 12.8 ALG) to BS EN 14449. Low-frequency noise like traffic and bass is the hardest to block, so it never disappears completely. Use the estimator below to hear the difference, compare the glazing, and get a spec with a quote.
How the estimator works
Pick the noise outside, from traffic to a busy office to a bar. Press play to hear it, then switch the glazing from single, to standard double, to acoustic laminated, and hear it dull and quieten. You see the certified Rw for each option and can send the result straight to a quote. Built for specifiers, facilities teams and anyone fighting a noise problem.
What the Rw number means
Rw is the single figure for how much airborne sound the glass holds back, measured in decibels. Higher is better, and every 10 dB sounds roughly half as loud. Our acoustic laminated glass is certified at Rw 36 to 39 dB. One honest note: against traffic and other low-frequency noise the working figure is a little lower, which is why heavy rumble is the last thing to go. For the detail, read

how soundproofing glass works.
It is the system, not just the glass
Acoustic glass only delivers its rating as part of a suitable framing system. The glass is one part of the answer, and the frame, seals and installation carry the rest. So treat the estimator as a guide, and let our team confirm the right build and the realistic result for your space. Every acoustic unit is laminated with a PVB interlayer, made to measure and Kitemark-approved.

Frequently asked questions
How much quieter does acoustic glass make a room?
It depends on the noise and the glass. ToughGlaze acoustic laminated glass is certified from Rw 36 to Rw 39 dB. As a rule of thumb, every 10 dB sounds about half as loud.
Does acoustic glass block traffic noise?
It reduces it, but low-frequency noise like traffic and bass is the hardest to block, so heavy rumble is the last thing to go and never disappears completely.
What is a good Rw rating for glass?
Higher is better. Our acoustic laminated glass is certified at Rw 36 to 39 dB to BS EN 14449. The right figure for you depends on the noise you are dealing with.
Is it the glass or the whole window that controls noise?
The whole system. Acoustic glass only delivers its rating with a suitable frame, good seals and proper installation.
