Side Hung Coupled Sash Window

A side hung coupled sash window is one of the original ways of making an isolated double-glazed window.

The window has the same characteristics as a normal side hung window, but at the same time it is equipped with an extra sash, which can be opened for cleaning. This extra sash gives the window very high insulating properties.

This type of window is typically used in cold climates and where a classic Scandinavian type of window is wanted.
