Typical Acoustic Benefits Reported:
Reduced traffic rumble and high-pitched sirens.Dampened noise from rain or hail on the glass.Tranquil sleep in busy city environments.2. Thermal Efficiency and Heat Retention
Secondary Glazing Disadvantages glazing serves as an effective thermal barrier. By producing a 2nd seal, it avoids cold draughts from getting in through the gaps frequently discovered in aging timber frames.
