Lipped Casement Windows

A Lipped Casement window is when the sash, the moving part of the window has a lip that slightly overlaps the frame.

Designed in the 1950s, this window was to be more weather tight than its predecessor the Flush Casement. But nowadays as modern technology has moved forward both Flush and Lipped casements are equally weather tight. It is more down to your own personal preference which style you choose.

Lipped Casement remains one of the most popular styles of windows and can be personalised to fit the style of your property by means of our many design options.
