Flush Casement Windows

Flush casement windows operate by the sash level sitting within the frame, giving them a signature smooth, flat appearance and slim sightlines that let more natural light into your home. Rather than overlapping the frame like a standard casement, the sash opens outward on hinge mechanisms, allowing for excellent ventilation while maintaining that sleek, uninterrupted look. Because the sash does not overlap, here at Art on Glass we fit every flush sash window with high quality seals to ensure a weathertight finish.

Despite their elegant design, our uPVC flush casement windows are low maintenance, built to last, and perform to the highest standards. They are PAS24 approved and Secured by Design accredited, and combined with double glazing and Liniar’s energy efficient profile, they are highly effective at keeping your home warm and your energy bills down.
