    The Science Behind Noise Reduction

    Secondary glazing doesn't just block noise—it uses proven acoustic principles to dramatically reduce sound transmission into your home.

    Sound Wave Interruption

    Secondary glazing creates a barrier that disrupts sound wave transmission, preventing noise from entering your home.

    Air Gap Principle

    The 100-150mm air gap between primary and secondary glazing is crucial for absorbing sound energy before it reaches your interior.

    Mass-Air-Mass Effect

    Two separate glass panels with an air cavity between them provide far superior acoustic insulation than a single thick pane.
