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 which has translated well into the modern age.

One of the significant differences nowadays, however, 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, we blend the best of the old and the new. We take the simple, space-saving practicality of traditional sash window design, 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. Why not take a closer look at some of the options we have available?

Our sash windows are beautifully painted in a choice of finishes, and for a more personal touch we can paint your windows with any RAL colour you desire.

We are adept at matching colours from the existing coatings or proposed samples, including stains and varnishes.

Our new sash windows include a full set of elegant traditional sash window fittings with every new window: sash lifts, pulley wheels, fitch or brighton fasteners and key operated restrictor locks, to ensure your home stays safe and secure.

On completion of installation a FENSA certificate is provided for your
property records.
