Our Stratophone soundproof glass – also marketed as ipaphon in the DACH region for a long time – offers a high level of security as laminated glass, but also effective sound insulation that keeps outside noise at bay.
Three values – Rw, C and Ctr – determine the sound attenuation performance. These are defined in EN 12758 and are specified in decibels (dB) in accordance with EN ISO 10140-3 between low-frequency sound (e.g. road traffic at low speed) and higher-frequency sound (e.g. children playing).
Stratophone
Stratophone sound-insulating glazing is provided with our high-quality iplus coating as standard and is therefore also “state of the art” in terms of energy efficiency. All types can be combined with almost all Stopray and ipasol coatings for additional functions.
