We have a number of systems available. Our most cost effective and popular, frameless single glazed system with a frameless door, is specified at 33dB sound attenuation. At this level you will hear muffled conversations. Our best double glazed system, fitted with acoustic glass is specified at 50dB sound attenuation.
We can provide a guide based on the test data on the glass type specified, but every building is different. The construction of a building and the furnishings within a room make a significant difference to the way sound behaves. If sound insulation is important to you then we have a number of ways to improve on the Standard system without increasing the cost beyond reason.
