Box Sash Windows

by Scott Edwards

The window manufacturing industry is now seeing a notable resurgence in the traditional sash window, also referred to as the “Box Sash” or “Sliding Sash Window”. This specific style of window frame will never become obsolete because it is an integral part of heritage buildings and a major feature within the legislation of local conservation authorities.

The majority of proprietors owning traditional buildings have no wish to remove these windows, whether their property is used for residential or commercial purposes. This is because the sash window gives so much character to almost any building in which it resides, and has been proven to increase value and saleability.

The most notable upturn with these windows is that they’re now commonly being designed into new build projects. Admittedly at the moment this is generally focused at the higher end of the market where there is likely to be a greater flexibility toward rather than constraints on budgets, but there is no doubt that the sash windows popularity is as strong as ever.

Over recent years there have been a number of improvements made to the sash window with greater seals, smooth action guides and the introduction of high insulation double glazing. The only issue with double glazing in a sash window is when Georgian style or marginal bars are incorporated into the design. To hide the spacer bar and unit sealant between the two panes of glass in a double glazed unit means that these Georgian or marginal bars have to be increased in section. On extremely large windows this is not a major issue, but on smaller windows or those with a large number of glazing sections the difference is notable.

To alleviate this problem there is now a new glazing unit called “Slimlite” which manages to achieve the same levels of insulation as a standard double glazed unit, yet is manufactured with a greatly reduced cavity, spacer bar and sealant. This unit provides the appearance of a single pane of glass allowing the window to be constructed in a traditional slim-bar style yet delivers all the insulation you would expect from a modern window.

Like all new and innovative products there is a cost involved, and one that some may find a little excessive. However, those prepared to go the extra mile by installing, or replacing traditional sash windows, and if necessary “Slimlite” glazing, can rest assured that the financial layout is a strong investment.

The oldest of sash windows have lasted literally hundreds of years, and their successors which have the added benefits of the modern age will be even more reliable. Installing sash windows today is really a once in a lifetime event as long as a realistic amount of maintenance is upheld.

There are few products where you can be guaranteed of such long term character, charm and reliability, and also know that you are upholding or improving a property’s appearance and value. By installing sash windows you will have done exactly that.
