Timber Casement Windows

To suit window replacements, renovations and new build projects we offer two casement windows design options – flush and stormproof. Both have been designed and manufactured to provide excellent thermal, acoustic, weather and security performance.

With a wide range of opening, layout and roundwork options, including arch top and circular, we are able to customise both flush and stormproof timber casement windows to provide a perfect fit for your project. In addition we offer a broad selection of paints, stains, glazing and furniture with the option of astragal or glazing bars.

Traditional butt hinges and casement stays can be specified for aesthetic detailing. We can also provide regency mock sash casement windows, finished with decorative horns to provide an authentic sash window appearance. For practical application we have a wide choice of hinges including egress, restrictor and reversible.

A casement window is one of the most common and popular styles of window on the market and a casement window attaches to its frame by a single hinge or more than one hinge and are held open by a casement stay. At George Barnsdale we range numerous varieties of casement stays and other casement window furniture to suit the style and design of your window.

Timber Casement Windows - Key Features

1 2 3 4 5 6

Click on a marker to view this key feature in more detail.

  • 1

    Multi-Point Locking (for High Security)

    Using multiple locking points and bi-directional cams, our casement window offers excellent security as standard.

  • 2

    Dual Weather Seals (For Excellent Weather Performance)

    For excellent weather performance dual weather seals are discreetly positioned within the sash of the casement window. They create a low pressure cavity which helps to retain warmth and exclude noise and moisture.

  • 3

    Hinge Protectors (for High Security)

    All of our casement windows are fitted with hinge protectors as standard, providing additional strength to prevent forced access.

  • 4

    Concealed Hinges (Ease of Opening)

    As standard all casement window designs are supplied with a concealed hinge located within the frame. The concealed hinge retains the opened window position firmly in place without the need for additional stays and is invisible from the inside when the window is closed. As standard, the hinge allows the window to open up to 90 degrees in order to maximise the opening for escape purposes.

  • 5

    Restrictor Hinge

    With a built-in safety restrictor, this hinge prevents the casement window from initially opening from more than 15 degrees. Like our standard hinge, the restrictor hinge is concealed.

  • 6

    Easy Clean Position (Ease of Cleaning)

    Our concealed hinges (including the restricted option), allow the sash, when opened, to slide towards the centre of the frame to enable the outside to be accessed for easy cleaning. We also offer a reversible hinge which allows the casement window to be completely rotated so that the outside of the glass is on the inside.
