What are Flush Sash Windows?
16th May 2023 - By Jason Clemmit
Flush Sash Windows are becoming popular for UK homeowners looking for a touch of high-end aesthetic in their homes. Available with modern or traditional styling, Flush Sash Windows are designed so that the window sash (the part of the window which can be opened) sits flush within the window frame for a sleeker and more streamlined appearance.
Timber Alternative Flush Sash Windows
This flush finish makes Flush Sash Windows an ideal ‘timber alternative’ option for homes that need traditional aesthetics with the modern 21st-century performance of a PVCu window. Many PVCu flush sash options are available in traditional wood-grain finishes, such as Oak and Rosewood, to mimic traditional timber windows.
They can also be manufactured using a mechanical or ‘butt’ joint rather than a standard 45-degree mitre-weld for ultimate authenticity. This makes them almost indistinguishable from traditional timber windows, so they can also be used on properties in conservation areas.
Using Flush for A Modern Finish
The clean lines of Flush Sash Windows also make for a stunning contemporary window option. Many homeowners who like the minimal styling of aluminium windows will opt for an Anthracite Grey or Black flush window to mimic the high-end aluminium look for less.

Flush Sash Window Openings
For ultimate functionality, Flush Sash Windows can be manufactured in a full range of window opening styles, including top-hung and side-hung casements.
If you have a bow or bay window, choosing flush sash frames can create a sleek new look for your home.
Flush Sash Window Materials
Flush window styling is available in a range of material options.
As the inspiration for their modern counterparts, Timber Flush Sash Casement Windows offer the traditional flush look with a handcrafted finish. Timber frames can be chunkier than more modern designs but boast natural warmth. Engineered timber and coating technology advancements mean less maintenance and repainting than in days gone by.
PVCu frames are among the most popular Flush Sash Window materials because of their clever design features, mechanical joints, and woodgrain foil finishes that can replicate a classic timber look in modern PVCu.
There is a third option of Flush Aluminium Windows, which can be more expensive, but will give a sleek, ‘Grand Designs’ look to your property. Aluminium is very strong whilst being light, so it is a good choice if you are looking for extra-large flush sash windows as they can hold larger and heavier glazed units.
Equal Sightlines & Dummy Sashes
Equal sightlines on windows are in high demand from homeowners looking for a clean and balanced look for their property.
When a window features an opening sash, it can create unequal sightlines next to a fixed window as the glass area for the fixed window is slightly larger than the glass in the opening sash.
A great design option that’s available with Flush Sash Windows is to use dummy sashes (sometimes called dummy vents). They are manufactured to look like the opening windows they sit next to and create equal sightlines across the window for a uniform finish.
