Flush sash windows
The flat, elegant face of traditional timber joinery with the warmth, security and easy upkeep of a modern uPVC window.
Windows
Character without the upkeep
On a standard casement the opening sash sits proud of the frame. On a flush sash window it closes level with it, giving one flat, uninterrupted face. It is how timber windows were made for a couple of centuries, and it is the detail that makes a replacement window look as though it belongs on a period home.
Paired with a heritage colour or a woodgrain finish, flush sash frames are a favourite for cottages, farmhouses, Victorian and Edwardian terraces and new homes designed to look established from the day they are finished.
Period proportions
A flat external face and slim, even sightlines that echo original timber joinery.
Heritage colours
Chartwell Green, Cream, Agate Grey and woodgrain finishes that suit stone and brick.
Modern performance
A-rated double glazing as standard with triple glazing available.
Quietly secure
Multi-point locking and internal glazing, with none of the hardware on show from outside.

The detail that changes everything
Stand across the road from a house with flush windows and you will notice the difference before you can say what it is. The frames read as a single plane, shadows are finer and the glass looks larger. It is a quieter, more considered window.
We can add Georgian or astragal bars to divide the glass into smaller panes, and match traditional details such as a deeper bottom rail, so new windows follow the pattern of the originals.
A sensible choice for sensitive settings
Flush sash windows are often chosen for homes in conservation areas and for properties where the original timber windows have reached the end of their life. Planning rules vary from one council to the next, so if your home is listed or in a conservation area, check with your local planning authority before you order. We are happy to supply drawings and specifications to support an application.

Questions
Good things to ask
Straight answers to the questions we hear most about this product.
What is the difference between a flush sash and a standard casement?
Only the way the opening part meets the frame. On a standard casement the sash overlaps the frame and stands slightly proud. On a flush sash it sits inside the frame and closes level with it. The glass, locking and thermal performance are equivalent.
Will flush windows be accepted in a conservation area?
They often are, because they closely resemble traditional timber windows, but the decision rests with your local planning authority and policies differ between councils. We recommend asking before you order, and we can provide product details for your application.
Do woodgrain finishes fade or peel?
The woodgrain is a durable foil bonded to the profile during manufacture, designed for decades of British weather. It needs no staining or varnishing, just an occasional wash.
