Flush Casement Window Materials

The flush casement windows we manufacture, and supply are made using Deceuninck’s Heritage uPVC profile. This excellent window system comes with unrivalled benefits across the board with superb energy performance, security, and durability. uPVC windows, in general, are low maintenance and can reduce energy and heating costs, and our flush sash windows are no exclusion to that.

Flush Casement Window Designs

Flush casement windows are distinguished by sashes that close into the frame and finish flush with the face of the window. As a result, they make for excellent timber replicas and can even replace the sleek design of aluminium. The stunning window with flush contours can be designed with external mechanically jointed corners to replicate timber joints and many other intricate pieces of detailing to attain this authentic look.

Do you offer flush Georgian windows?

Our flush sash windows are available with astragal bars to match Georgian windows. We make all our flush sash windows in-house and the homeowner, therefore, has the flexibility of choosing their own bar layout to recreate a window design from their chosen era.

Are flush windows more expensive?

The flush sash window style is a premium offering and therefore generally, the flush sash style is slightly more expensive than classic casement windows.


Are flush fit windows considered heritage windows?

Heritage – or traditionally styled windows – are growing in demand, in particular the flush sash. It is fair to say that they have invigorated the replacement window market, where just a few years ago the choice for most homeowners replacing their windows was standard casements. Flush sash windows sit alongside our sliding sash windows offering true heritage window designs.
