    Secondary Glazing in Upper Holloway — Your Questions Answered

    Do I need planning permission for secondary glazing in Upper Holloway?+
    In most cases, no.

For Upper Holloway 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.

This makes secondary glazing an ideal fit for victorian terraced houses with sash windows, edwardian period properties, converted flats and maisonettes and other typical Upper Holloway property styles, preserving sightlines and heritage character.

Every quote is prepared after a free on-site survey, so pricing reflects your exact window sizes and specification.
