The elasticity of the PVB membrane present in the Triplex glazing exhibits significant sound-absorbing capabilities.
In particular, it eliminates the effect in medium and high frequencies, between 1,000 to 2,000 Hz.
It is a reliable and relatively economical solution, especially in areas with increased vehicle traffic and trains and close to airports.
