Installing Sash Windows?

The popularity of sash windows is back on the rise, with more newly built properties being designed to incorporate this attractive feature and owners of period properties seeking to restore existing sash windows rather than replacing them with more modern styles. There are several questions that anyone buying and installing sash windows in their home should bear in mind, and here we look at some of the main issues to consider.


Before rushing into choosing a type of sash window, it is important to look at the property type. Choosing sash windows to complement that style of a property is paramount to maintain an attractive appearance, so if, for example, a house dates from the Edwardian period, adequate research must be put into finding sash windows that reflect this architectural style.

Repair Or Replace

Before pulling out existing sash windows to replace them with new ones, homeowners should first consider whether it is possible to restore the original windows. Wooden frames can almost always be repaired effectively and will look much more authentic in the long run.

Timber Or Plastic?

Today it is possible to choose from either traditional timber framed sash windows or more modern UPVC options. There are advantages to either choice – timber framed windows are more stylish and have a more authentic look and feel, however UPVC windows are much cheaper. In general, timber sash windows are thought to be the best choice as, contrary to popular belief, they are quite low maintenance and very hard-wearing while plastic frames, although quite durable, can be difficult to repair.

How Many Panes?

Sash windows are made up of several small panes of glass held together by glazing bars. Homeowners will need to decide how many panes they require, and what configuration is best – whether that be two by two, six by six, eight by eight, Venetian or Queen Anne Revival. The choice will probably be dictated by the home’s age and style.

Double Or Single Glazed

Today’s building regulations make using traditional single glazed windows very difficult, although in some renovations, single glazing is permitted. A similar effect can be achieved with double glazing however by using spacer bars between sheets of glass.
