Explore Secondary Glazing Noise ReductionSecondary glazing can reduce noise levels by 70-80%, which translates to a reduction of 45-50 decibels. The exact reduction depends on the air gap size, glass type, and installation quality.
Laminated acoustic glass (6.4mm or 6.8mm) provides the best noise reduction. Using different glass thicknesses in the primary and secondary glazing prevents resonance and blocks a wider range of frequencies.
A larger air gap (100-150mm) provides significantly better noise reduction than smaller gaps. The air cavity acts as an acoustic buffer, with larger gaps being more effective at blocking low-frequency noise like traffic rumble.
