Sightlines

Searching for window products online, you’ll soon come across manufacturers boasting of a particular product offering ‘reduced sightlines’ or, perhaps, the even more vague ‘superior sightlines’. What are these ‘sightlines’?

Combining fixed sashes with opening sashes on a window unit usually means that the upper and lower glazing lines are uneven – because the opening sashes have a smaller glazed area.

Equal sightlines are aesthetically desirable on many houses. The effect can be achieved by specifying flush casement windows – examples include Residence Collection R7 / R9, Deceuninck Heritage and Evolution windows.

Flush casement window – the upper and lower glazing lines are level.


A more economical way of achieving equal sightlines is to fit dummy openers to non-opening sashes of a standard (non-flush) window so that the glazed dimensions of fixed and opening sashes are the same.

Aluminium window frames are slimmer than uPVC or timber frames – hence they offer ‘reduced sightlines’. This means that you’ll see less frame and more glass.
