A sleek, modern alternative to traditional casements. Our made-to-measure flush casement windows are designed and installed by Reflect Projects across Hertfordshire.
Flush casement windows differ from standard casements in one key way — the sash sits flush within the outer frame rather than sitting proud of it. The result is a clean, uninterrupted sightline that suits both contemporary and traditional properties. Reflect Projects supplies and installs flush casement windows across Hertfordshire, made to measure in a wide range of colours and finishes.
