SLIDING SASH WINDOWS

Sliding sash windows have been around for over three hundred years. They were manufactured as large windows to allow the maximum amount of light to come into a room. The problem at that time was the inability to make glass panes in large sizes. As a result glazing bars were introduced to carry the smaller panes that were available.

Sliding Sash Windows were traditionally single glazed with a 3mm thick glass pane. Today we use 4mm glass and the units are often double glazed so the weight of the unit has increased dramatically. The modern design accommodates these changes with a wider sash with heavier counter weights encased inside. We can, of course, still produce Traditional Sliding Sash Windows, single glazed if required for a property in a Conservation Area, but we can also upgrade them using weatherstripping (which is hidden from view). With regard to maintenance, modern paint finishes provide a re-decoration period of seven to ten years for a solid colour and five years for translucent stains - depending on the aspect of the window.
