What are Flush Windows?
Flush sash windows are a style of window with no overlap of sashes,
meaning the exterior of the window remains sleek and flush. The stylish
design is reminiscent of a traditional, pre-1932 timber window.
They offer the timeless charm of traditional timber joinery, with slim, well-balanced proportions, while benefiting from a modern uPVC construction for better insulation, security and ease of upkeep.

Difference Between Casement and Flush Windows
Flush designs provide a modern twist on more traditional outward-opening styles. On a standard frame, the opening section typically sits proud of the outer frame when closed. With flush-fit designs, the sash finishes level with the frame, giving a flatter, more streamlined appearance.
At Phair Windows, we manufacture and install both contemporary flush frames and more sculptured or chamfered profiles, in both uPVC and aluminium, with an extensive choice of colours and finishes to suit your home.
Flush Window Prices
All of our high-quality frames offer excellent levels of energy efficiency using the latest A++ glazing technology at an affordable price. Flush-fit designs typically sit towards the premium end of our range thanks to their refined aesthetics, but flexible finance options help spread the cost to suit your budget.
Throughout our years in the trade, we’ve installed and replaced standard casement frames, wood grain uPVC windows, aluminium, Georgian style windows, sash windows, bay and bow windows, tilt and turn windows to a variety of home across the East Midlands.

Frequently Asked Questions
What is a flush sash window?
Flush windows feature opening sashes that sit level with the outer frame when closed, creating a smooth, even surface rather than a stepped profile. This delivers a neat, understated look that works beautifully on everything from cottages to new-builds, resembling the sleek styling of aluminium windows.
Are flush windows more expensive?
Flush designs typically cost more than basic styles due to their refined engineering and premium aesthetic, but the difference is often small. Their authentic timber-like finish, superior energy efficiency and long-term durability make them excellent value that lasts decades.
What is the difference between casement and flush sash windows?
Standard designs have sashes that sit slightly proud of the frame when closed. Flush sashes finish completely level, giving a flatter, more contemporary profile. Both use modern materials for security and insulation, but flush offers that authentic heritage look with cleaner sightlines.
Are flush windows good?
Absolutely. They balance timeless style with cutting-edge performance, A+ energy ratings, multipoint security, and minimal maintenance. With mechanical joints, slim profiles and authentic woodgrain finishes, they’re ideal for period homes or anywhere you want elegance without upkeep.

Professional, skilled, great communication from the on-site team - honestly, the best workmen I’ve ever had. They left the place tidy and neat. Thanks guys! They did a great job on a dreary, winter’s day with a smile. I love the new porch, which was a decent price. Honestly though, the sales guy Tom and the crew of Cal, Jake and Aaron were great. After having had a bad experience before with a different company, I’ll be using Phair Windows to replace my windows in the near future as well.
