Whether you own a period cottage, a Victorian terrace, a farmhouse or a contemporary new build, our flush sash windows provide a beautifully neat finish that enhances kerb appeal and comfort in equal measure.

Flush sash windows are designed so that, when closed, the sash sits flush with the outer frame rather than overlapping it. This creates a smooth, streamlined appearance that closely mirrors traditional timber windows often found in heritage and character properties.
Because of their understated lines and balanced proportions, flush sash windows work brilliantly on:
Period homes: cottages, farmhouses, Georgian and Victorian properties
Heritage and conservation properties: where a traditional look is essential
Modern homes: where a clean, minimalist aesthetic is desired
You get the charm of timber with the practicality of modern window technology.
