How does a structural glazing facade contribute to acoustic insulation in airports, hotels, and offices?
Structural glazing façades improve acoustic performance by using laminated glass with sound-damping interlayers, wider IGU cavities, optimized glass thickness combinations, and airtight silicone joints that reduce vibration transmission. Because structural glazing eliminates exterior pressure plates, fewer gaps exist for sound to penetrate. In airports or transport hubs, laminated IGUs with acoustic PVB layers achieve sound-transmission class (STC) ratings suitable for high-noise locations. Silicone joints also outperform EPDM gaskets in sealing efficiency. Acoustic modeling software helps engineers predict façade performance based on panel size, cavity depth, and interlayer composition.
