Why Choose a Flush Sash Casement Window from Deceuninck?

3 min read Windows

There’s no doubt that flush sash casements are a fine choice of window. Although this is the style of window you like, there are still various manufacturers to consider for Flush Sash Casement windows. A leading brand you should consider is Deceuninck.

For those who aren’t quite aware of what a flush casement window is, it’s a window that is characterised by openers that close into the frame. The ‘flush’ part of the window is a description of the window’s look – the opening part of the window doesn’t project out of the frame, it lies flush in the frame when closed. This is the key selling point of a flush casement window. It’s a modern looking window with invisible joints, clean lines and a flat finish.
