    Frequently Asked Questions

    What is flush sash window?

    Flush sash windows, also referred to as flush casement windows, are identified by sashes that align seamlessly with the exterior surface of the window. When these windows are closed, the sash lies flush with the outer frame, resulting in a sleek and uniform external appearance.

    What is the difference between flush and non flush windows?

    A flush casement design is characterised by its flatness, achieved by positioning the window sashes precisely even with the window frame. In contrast, a non-flush casement window features sashes that slightly extend beyond the window frame.
