Flush sash windows—also known as flush fit windows—offer a timeless, elegant aesthetic by sitting flush within the frame, replicating the appearance of traditional timber windows. Whether you’re restoring a period home or giving a modern property a clean, minimalist upgrade, flush sash windows combine authentic looks with the low-maintenance durability of PVCu.
Why choose flush sash windows
Authentic appearance: The sash sits level with the outer frame, mirroring the sightlines and proportions of traditional timber joinery.
Low maintenance: PVCu resists rot, warping, and fading, so you get the classic look without the upkeep of painted timber.
Improved security and weather performance: Modern flush systems include multi-point locking and high-performance seals that enhance security and thermal performance.
Versatile styles: Available in a wide range of colors, finishes, and hardware options to match period detail or contemporary minimalism.
