What Are Sash Windows?

Sash windows were, traditionally, single-pane systems. These windows work, traditionally, by sliding one sash over another to open and close. Sash window systems are evident in many traditional and classic buildings; however, it is a style that has translated well into the modern age.

However, one of the significant differences nowadays is that sash windows use more than one sheet of glass. It is common for you to see double-glazed windows in London and elsewhere. Double and triple glazing are modern window standards we feel all homes can benefit from. While traditional sash used by UK homes in the past may have served a practical use, they may not have offered the most comfort and warmth.

Therefore, as a leading specialist in London, we blend the best of the old and the new. We take traditional sash window design’s simple, space-saving practicality and introduce modern comforts and standards. This way, homes can benefit from the stunning, customisable looks of a sash window while getting all the warmth and comfort benefits of the modern era. Our window innovations lead the way in terms of flexible, practical design. Let’s take a closer look at some of our available options.

Should you have special requirements there are also upgrade options to further increase the efficiency of your windows.

Sometimes it’s nice to close your windows and shut the outside world out! Specialised acoustic glass can reduce external noise pollution leaking into your home by up to 60%.

Technically speaking acoustic glass has an additional lamination which features an interlayer not seen in standard double-glazed windows. It’s this extra layer that can shut out extra noise such as road traffic, overhead planes and railway lines. Importantly this extra layer does not negatively effect the light flow into your room, and so you can enjoy reduced noise without effecting the look of your windows.
