What are flush casement windows?

Flush casement windows are a type of window where the window sash sits flush with the frame, creating a smooth, flat exterior without the protruding edges typical of traditional casement windows.

Are flush windows better?

Flush windows can be considered “better” in certain ways, depending on your priorities. Their sleek, flat design gives a modern, minimalist look that blends seamlessly with a building’s exterior. However, they often cost more than standard windows.

What is the difference between flush and non flush windows?

The main difference between flush and non-flush windows is how the sash sits relative to the frame. In flush windows, the sash is aligned with the frame, creating a flat, smooth exterior for a modern, streamlined look. In non-flush (or traditional) windows, the sash projects slightly from the frame, giving a more classic appearance with visible edges or detailing.

What are the benefits of a flush window?

Flush windows offer a sleek, modern look because the sash sits flush with the frame, creating a smooth, minimalist exterior. They are low-maintenance, easy to clean, and provide good weather resistance and insulation. Made from uPVC, they are long-lasting and versatile, blending well with contemporary homes.
