Shaped windows add an element of style to your property.

Arched windows, Circular windows and Fanlights

Arched windows in particular feature heavily in Georgian architecture. Victorians also included arched top sashes in sash windows. Bespoke timber joineries like ourselves can match these designs in timber windows. Furthermore, if the windows are new or to be refurbished it is equally possible.

The function of the arch in windows is to maximise the light coming in by increasing the surface area of the window.

It is possible to double glaze fanlights and arched windows. In period properties these windows can be refurbished. Expert joiners, such as Timeless Sash Windows, repair the timber and where necessary will splice in new timber sections. Next our spray painter Gerry will finish paint the fanlight with 3 coats of Teknos exterior joinery paint. Finally, the glazing team will insert the glazing units and putty seal them.

The glazing units that we use in all windows and doors are ordered on a case by case basis. As such, we can use arched or even curved glass in specific windows. It is also possible, although costly, to double glaze old glass.

Another way to let light in is with a fanlight above a solid door. This is a common feature in period architecture. In some properties these are leaded lights or stained glass. Whereas is some homes they are a simple double or single glazed unit.
