    Secondary Glazing in Muswell Hill — Your Questions Answered

    In most cases, no.

For Muswell Hill homes exposed to heavier traffic or urban noise, our 10.8mm acoustic laminate specification delivers up to 80% perceived noise reduction (around 45–50dB), thanks to the wide 100–150mm air cavity between the original window and the new internal pane.
