Combining ultra-slim sections with simple shapes, Stellar’s fully flush casements are versatile. The frame simply isn’t allowed to dominate the view and the clean simple shape allows other architectural elements in your home to shine.

Flush inside and out, this is a high-performing window with graceful looks that hide remarkable strength. You’ll enjoy more comfort with Stellar’s insulation, more reassurance with its secure design, and more time to yourself because these windows are virtually maintenance free.

Every fully-flush casement window is a bespoke product. Made to your exact specification, with your choice of layout, glass, finish and hardware.
