Why timber sash windows?


Timber Sash Windows, otherwise known as a box sash window, is a traditional type of window that has been used for hundreds of years. It consists of panes of glass in which the lower pane slides up and down in a channel, opening and closing the window. When it comes to choosing a new window, you want the best. Timber sash windows are an industry standard for homes simply because they look and feel better than any other. And timber has many benefits that go way beyond aesthetics. Timber Sash Windows are available in timber construction and vary in appearance depending on the period of construction and the style that was fashionable at the time they were constructed. At Trade Timber Windows and Doors London, our timber sash windows provide an aesthetic and traditional style. They work primarily with single glazed, double or triple glazed units with hinged or sliding sashes. This makes them extremely versatile when it comes to our customers’ needs, such as the use of supplementary heating systems that are commonly fitted within sash window openings.
