How to reduce noise with a curtain wall glass system?

Urban centers like Manama or Kuwait City require curtain-wall designs that mitigate traffic and construction noise. Acoustic performance hinges on laminated IGUs with unequal glass thicknesses (e.g., 6 mm/10 mm) and thick PVB interlayers; these combinations can achieve Rw 45–50 dB. Deep mullion profiles with elastomeric acoustic gaskets prevent flanking noise around the frame. Aerogel-infused cavity blocks act as acoustic baffles within pressure-equalized profiles. Attic ceilings adjacent to curtain-wall perimeters can use perforated aluminum ceiling panels with mineral-wool backing to absorb residual reverberations. Proper sealing at mullion-to-glass and slab-edge connections is critical; use acoustic silicone compliant with ASTM C acoustic standards. Together, these measures create serene interiors despite external noise.
