Sash Windows

Sash Windows Made For You

Sash windows consist of one or two moving glass panels which open by sliding vertically. A system of weights, cords and pulleys support and balance the panels. Some sash windows also follow Georgian window frames. The internal frame surrounding a sash window is a main interior design feature in a room, which enhances the amount of natural light and forms a lovely and classical feel.

Old timber sash windows are prone to rattle and provide poor insulation. If not correctly maintained, the wood can also show shrinkage and distortion. The Marvin Architectural team of technicians and installers have replaced conservation approved sash windows in very prestigious buildings such as Eton College.

Georgian and Victorian Sash Windows

Sash windows have been around England for centuries. The box sash window can find its origins in 17th Century London and it was the most popular window design after the great fire of London (1666). Examples of which can be seen in the remodelled Hampton Court and Kensington Palace.

The original multi-paned sash window (6 over 6) became popular in the Georgian Period 1714 -1811 and over a period of 150 years with advances in glass manufacturing developed into 4 over 4 pane commonly referred to as the Victorian style. The sash window while not as popular in postmodern architecture is still a favourite with some homeowners who prefer the classical proportions of the sash window.
