Sound insulation (Noise Insulation) is an important feature of your joinery. It is determined by the different parameters of the glazing used. Good noise insulation depends on the following:

• The use of different air chambers and glasses increases the noise insulation. Various resonant frequencies of the glasses are obtained. For example, triple glazing (6 mm + 5 mm + 4 mm) has a better noise insulation than glazing of (4 mm + 4 mm + 4 mm) or (6 mm + 6 mm + 6 mm).
• For better noise insulation (noise insulation), we recommend the use of triple glazing – it allows for a good combination of glass of different thickness.
• The gravity of the glass also has an impact on its noise insulation capabilities. The heavier it is, the better they are.
• The distance between glasses is also important. In principle, the greater distance allows for better noise insulation. However, it is important that this distance is optimized by professionals in view of the other parameters, so that there is no consequent negative impact on the thermal insulation properties of the glazing.
• The use of gas (often argon or a mixture of gases) instead of dry air in the glazing allows not only better thermal insulation but also better noise insulation. The exclusion is made by the glazing, which is sealed with silicone – it is not recommended to fill with gas as it passes through the silicon.
