Wooden Timber Sash Windows

Wooden Sash Windows are typically seen in older style and period properties but in recent years have become popular with more modern homeowners. Beautifully crafted and authentic Timber Sash Windows certainly add an elegant and timeless finish to many styles of property and their rich history adds to their charm. Properties dating from the 17th up to the 19th century would almost exclusively have had Wooden Sash Windows fitted as a matter of course. And even today, Timber Sash Windows are still required when renovations are carried out period properties, especially those in conservation areas.


If you are considering having Wooden Sash Windows fitted to your home it’s very important to consider all the factors of function as well as style and form. Whatever the project be it a modern home or Timber Sash Windows within a property restoration, the quality of the materials, cords and counterbalance weights can all make a difference to the functionality and durability of your chosen Wooden Sash Windows. Here is an overview on Timber Sash Windows:

What is a Wooden Sash Window? 

In simple terms, a Wooden Sash Window is a window containing one or more moveable, sliding panels termed ‘sashes’ set inside a wooden frame. A classic Timber Sash Window typically comprises of two sashes which slide up and down, one in front and the other behind, in vertical grooves, with lead weights on cords to counterbalance them. You can open these windows at the bottom or top – or both. If only the lower sash is movable while the upper sash is fixed, this is known as a single-hung sash window. If both sashes are moveable, this is known as a double-hung sash window. In more modern times, Wooden Sash Windows have been designed to also tilt inwards and outwards for easy cleaning and maintenance.  

How does a Timber Sash Window work?

A Timber Sash Window can slide vertically and/or horizontally by means of the inner workings of a pulley system, counterweights, and heavy-duty cords within the timber frame to any chosen position. Thanks to the hidden weights inside, one or both sashes remain in the open position without sliding closed.

What styles of Wooden Sash Windows are available? 

Over time the styles and designs of Wooden Sash Windows have changed. So, if you’re in the process of restoring or replacing Timber Sash Windows, ensuring that you match right style to your period of home is crucial.


A conventional style for Georgian era homes is the sliding Timber Sash Window. This features six smaller panes of glass per sash held in place by thin glazing bars. The Half Georgian is very similar in design but only the top sash features the six smaller panes while the lower sash is filled with a large, single pane of glass.  During the Victorian era the predominant style of Timber Sash Windows was known as a ‘centre bar’, style, this featured  two larger panes per sash. For Edwardian properties, it was more common to have six smaller panes in the top sash, with two larger panes in the lower sash. It should be noted that whilst these are the most standard styles of their period, there is also a wide range and plenty of variations in Wooden Sash Windows to consider, including True Arch, Swept Head, and Asymmetric styles. 

What are the key benefits of Wooden Sash Windows?

Increased air flow in and out of the property:  this is one of the major benefits of double-hung Timber Sash Windows. When both sashes are open by equal amounts, the top sash allows warm or stale air to escape, while the bottom sash draws in cooler, cleaner air from outside. 

Ease of maintenance:  Despite what many think, Wooden Sash Windows don’t have to be high maintenance. Timber is known for its durability if correctly maintained and is also an excellent insulator if cared for correctly. In today’s’ Wooden Sash Windows there are a wide range of contemporary finishes and colours available. Composite models, with wood on the inside and aluminium on the outside are growing in popularity, as they combine the look of traditional wood with the weather resistance and low-maintenance factor of aluminium.
 

Security and durability: Timber Sash Windows which are double glazed Sash Windows are highly durable and hard to break. However, if you require the very highest levels of security then you would do well to consider triple glazed Wooden Sash Windows which, by their nature, offer extreme strength and durability. Locks can of course be installed on Timber Sash windows to allow the windows to be safe and secure and still be able to opened for ventilation.
