    Deceuninck flush sash windows

    Deceuninck flush sash windows are the perfect choice for heritage property installations. Once installed the window frame sits flush with the exterior property wall to create a smooth uniform aesthetic. This perfectly recreates the appearance of original timber windows, and the frames can be finished with a realistic timer-effect coating to further accentuate the period effect. They are also gaining popularity in more contemporary installations thanks to their sleek finish and unique style.

    Deceuninck 2800 Heritage Sculptured Windows

    Deceuninck 2800 Heritage Sculptured Windows are similar to the Chamfered model, sitting proud of the frame and opening outwards. Heritage Sculptured Windows, however, feature more profile detail than their Chamfered counterparts. They feature more architectural lines on the profile face to give a more machined appearance. They are popular with properties with clean architectural designs as their straight lines tastefully complement a more understated aesthetic.
