Victorian Sash Windows

Victorian Sash Windows are a traditional style of window based on a design that has been around for centuries. These sash windows were largely used in the U.K during the 19th century and before, and can vary in style and pattern depending on where you live in the country.

Originally designed to let in cool air during summer and retain heat during winter, they feature large frames with moveable panels known as sashes.  

Sash windows may date back to the 16th century, but Victorian-style sashes became uniquely popular across England and Wales between 1835 and 1870. The majority of properties in many towns would have used this style of window during this era – today they’re classed as a cultural asset and on many homes considered part of the building’s identity.

Georgian Sash Windows

Four centuries on, Georgian-style sash windows still look stylish and elegant, continuing to add beauty and elegance to any property. The term ‘Georgian’ is used to describe a period in English history that lasted from 1714-1830, but the style still remains popular today due to its timeless appeal. So whatever your preferences for decorating your home, if you want your windows to give an authentic Georgian feel then you can’t go wrong with traditional sash windows. Georgian sash windows are, as the name suggests, an authentic representation of Georgian window designs. Made of traditional wood and glazed with a vast variety of attractive glass options available to suit every home. They feature four panes that can be opened individually in order to control the amount of air, light and privacy they offer. Whatever your choice of sash windows for your London property, you can be sure that we have what it takes to deliver.

Sash Windows Glazing Options

Double Glazed

A Double-Glazed Sash Window is a traditional vertical sliding sash window which has an airtight seal created by a permanent sealing bead that runs the full height of the frame. Double sealed glass units are incorporated into the frame to create a higher level of security than a standard window. The sashes are permanently held in place with two secondary dowel pins and twelve self-tapping screws, making them virtually impossible to remove without damaging the window frame.

Triple Glazed

The replacement of your period style sash windows with triple glazed versions is the most effective way you can upgrade their thermal performance at a reasonable cost. Triple glazed units consist of three panes of toughened safety glass with a high quality aluminium spacer fixed onto a factory finished timber frame. The aluminium spacer system provides for easy sliding whilst maintaining optimum air sealing.

Sash Windows Colour Options


We use a specialised range of PVC colours for our sash windows, so you`ll find options that suit your home’s design, style and personality.

  • White
  • White Woodgrain
  • Olive Grey

If you are looking to install sash windows, or change the timber sash colour, it can be confusing when making a choice. Depending on what look you require, there are six major colours to choose from for timber sash windows including: light oak; golden oak; mahogany; teak; redwood and silver ash. Have in mind that the same window will differ in appearance depending on the colour of the sashes. As you would expect though, lighter colours will create more natural light into a room, but darker coloured exterior wood is better protected from the elements as it doesn’t let as much light through.

  • White
  • Cream
  • Cream
  • Paint
  • Agate Grey

Are sash windows easy to break into?
New sash windows manufactured to ancient standards are difficult for most people to break into, due to the strength of the sash and old- fashioned sash cords.

However, in some areas of LOCATIONXX,X with large numbers of secure flats, criminals have been known to gain entry by breaking the glass in a window then using the jagged edge like a crowbar to lever open the frame.

This is why well-maintained period sashes should be hidden behind secondary glazing or security film when not in use. If you are interested in having your period windows reinforced, speak to one of our specialists on 020 452 51670 or emailXXX.
