    Nurseries have a problem adult bedrooms do not: the sleep happens during the day, when London is at its loudest. Deliveries, refuse collection, school run traffic and street works all peak in exactly the window when a baby is meant to be napping.

    A nursery specification therefore prioritises daytime broadband reduction and child safety. Laminated glass is standard in every unit we fit — if struck it holds together in the interlayer rather than breaking into fragments.

    Daytime noise is a different problem

    Between 08:00 and 18:00 a typical London residential street runs 8-15dB louder than overnight, and the events are more varied — reversing alarms, wheelie bins, car doors, drilling. Broadband reduction matters more than tuning for one dominant source.

    • Refuse collection: 85-95dB impulsive peaks
    • Reversing alarms: 1-2kHz, highly arousing
    • School run and delivery traffic: sustained mid-band
    • Street works: broadband, unpredictable, weeks at a time

    Safety detailing for a child's room

    All our acoustic glass is laminated, which is inherently safer than toughened or float glass in a room where a child plays. Fittings are specified without accessible pinch points, and catches on lift-out panels are positioned above child height.

    Where the nursery window is a designated escape route, we fit sliding or hinged units with tool-free operation rather than lift-out panels.

    Thermal comfort as a side effect

    Nurseries are usually kept warmer than the rest of the house, and single glazing makes that expensive and draughty. The same installation drops the window U-value from around 5.0 to 1.8 W/m²K and eliminates the cold downdraught next to the cot.

    Case study: Nursery on a Camden delivery route

    Camden, NW5

    Problem: 58dB daytime average with 88dB refuse-collection peaks; naps consistently cut short.

    Solution: Single 10.8mm acoustic laminate slider at 150mm cavity with child-height catch positioning.

    Result: Daytime level reduced to 29dB; refuse collection no longer audible enough to wake the child.
