Your spec goes to the ToughGlaze team, who confirm the build and the expected result for your project. TG AG is Kitemark-approved and made to measure.

About the figures. Rw values for TG 11.5 TALG and TG 12.8 ALG are certified for the glass to BS EN 14449. Single and standard double glazing figures are typical reference values. Acoustic glass only performs as part of a suitable framing system, so confirm the build for your project with the ToughGlaze team. About the sound. It is a synthesised illustration of how acoustic glass changes noise, not a calibrated playback, so your own volume sets the loudness.
