Flush Fit Windows

Our Flush Sash uPVC WIndows combine the elegance and style of traditional timber with all the benefits of uPVC. This range is ideal for those who wish to add or improve the period features of their homes. Its unique, unrivalled, aesthetic appeal makes this range the most attractive suite of windows and doors on the market today.

Top Security

There’s no compromise when it comes to security. The bespoke locking keep has a useful night vent locking position, which gives great ventilation whilst maintaining your security.

Our wide range of modern, contemporary and period style windows incorporate the latest built-in safety features, including internal glazing beads and multi point locking systems. To provide enhanced resistance to forced entry our windows can be fitted with a hinge protector device between the frame and the sash opener. Anti-bump, anti-snap key locking cylinders can be installed on all our doors to further enhance their security.

Superior Performance

To keep out the wind and rain we use our patented high performance, multifunctional weatherseals. The airtight seal this creates helps to maintain your comfort inside your home.

The Flush Sash dual seal is exceptionally watertight, with the added benefit of concealing any hardware.Any water that has found its way inside is quickly evacuated due to the intelligently designed integral drainage gutter.


Flush Sash windows look great in any surrounding, from country cottages to modern townhouses. Their subtle charm and elegance will transform your home. If you live in a Conservation Area, home improvements such as replacing your windows and doors will require planning consent as there are strict guidelines to ensure that architectural features are preserved.

The Flush Sash Window and Door Collection have been designed with this in mind; replicating the appearance and style of traditional timber windows with features such as our authentic Wood Grain Finish, Monkey Tail Handles and Georgian Bar options. However, you should always obtain consent from a planning/ conservation officer before proceeding with an installation.

Smooth Corner Weld

Easy to maintain, energy efficient and boasting an innovative smooth corner weld design that lets you make a distinct style statement, the Flush Sash window is the revolutionary new choice for all homeowners that wish to install uPVC windows and doors.
