Timeless Sash Windows

Ireland's Highest Quality Sash Windows, Hand Crafted in Meath

A sash window can be best described as a vertically sliding window typically made up of two sashes which act as a frame for the internal glass and glazing bars. The first evidence of this architecture in the UK and Ireland can be dated back to the late 1600s, from which the popularity of sash windows grew immensely throughout the 18th and 19th century. In the mid-1850s glazing bars which separated the glass were slimmed down to give the windows a slicker look. Around this time plate glass also started to be used. Having sash windows with plate glass demonstrated the wealth of the owner as well as being undoubtedly stylish.

To facilitate the up and down nature of sash windows, sashes are usually balanced by hidden sash weights which are in the window frame. This cavity needs to be allowed for when constructing the walls of the house. If not the walls may need to be modified or spiral balances can be used. The fact that both sashes are usually opening allows for optimal ventilation. As the warm air in a room rises it creates lower pressure towards the bottom of the room. This invites fresh air in from outside as the warm air is pushed out above the top sash. Because of this a room can be ventilated without a draught flowing through the room. The design of a sash window allows for this ventilation even with a small opening at the top and bottom of the window, ideal even for when it’s raining. Draught proofing, the use of double glazing and enhanced timber quality are recent improvements which allow the traditional design to comply with the latest energy efficiency requirements.


Our people, our craftsmanship, our quality product and aftercare are just some of the many reasons people choose Timeless made windows.

There are a number of different styles mainly, Edwardian, Georgian and Victorians. These vary from are one over one pane, two over two pane, three over three pane, four over four pane and six over six pane. You can also have margin bars.

The choice of style depends on the location of your property e.g. if neighboring homes have a certain style then generally this is the style that is replicated. If you are in a conservation area it is a requirement to replicate what the original window style once was. No one style is better than the other however the cost will increase with the greater number of glazing bars you have.

There are also a number of different designs you can have. These include:

• Shaped

• Arched
