Ever-increasing noise levels are a leading characteristic of modern society. Protection against noise pollution becomes one of the most important aspects of daily life, as it directly impacts our mental health. Moments of quietness and tranquility become increasingly rare, while comfort becomes synonymous to achieving adequate noise protection.
The soundproofing properties of the VASGLASS product line offer a significant reduction in ambient noise levels and an effective protection against noise pollution.
The performance of soundproofing glass is measured by the value of its sound insulation index (R) for a stated frequency of noise reduction, or its weighted sound insulation index (Rw) for a range of frequencies. Since float glass is a relatively poor sound insulator, the VAS-SAFE ACOUSTIC product line of laminate glass, combined in double and even triple glazed systems, offers levels of sound control with a weighted sound insulation index Rw of up to 52dB.
The soundproofing performance depends on the level of symmetry of the layout of the individual glass panels used in a particular system. For the proper design of a sound insulating system a number of parameters must be known in advance, such as the frequency of the sound that we seek to suppress. The noise reduction level, such as the level of sound control depends both on glass thickness and sound frequency.
For a specific frequency, each type and width of glass sheet has different performance characteristics. Generally, sound insulation performance increases with frequency however beyond a critical frequency performance deteriorates.
