Choosing single glazing

Windows that are single glazed have just one single pane of glass within the window frame – ie. just one glaze. If you look at a window that’s single glazed, it should be clear that there’s only one sheet of glass between the inside and outside of your window.

Why choose single glazing?

There are advantages and disadvantages of single glazed windows. The main advantage is the lower installation cost compared to double or triple glazing. The main disadvantage is the poor energy efficiency, which can lead to heat loss, higher heating bills and condensation. If you live in a listed building or conservation area, you might not have a choice but to keep your existing window frames and retrofit double glazing to original wooden frames.

Insulating single glazed windows in period homes are a good idea when the weather starts to get colder. By insulating your windows, you can keep the heat in, lowering your heating costs. You also don’t have to deal with a cold draft as you wake up in the morning, something that every member of the home will greatly appreciate.

    Does single glazing provide insulation?
    Single glazing provides very little insulation to your house or garden building. Any heat is easily able to escape when it comes into contact with the window. If it is cold, then you can expect to lose heat from inside due to this lack of insulation.
    Will single glazing be prone to breakage?
    Since it is manufactured from just one pane of glass, single glazing can be very fragile. It breaks easier, and can even shatter on impact. This means windows are more likely to get broken in general, but may also be a security concern.
    Will I be able to keep my existing sashes?
    The lightweight properties of single glazing mean that you can keep existing pulleys and weights.
