Open any property to the surrounding environment with our innovative French Casement Windows, providing totally unobstructed views with the assurance of swiftly exiting the building when required.


Clear View


Hinges open to a full 90° angle with one opening sash carrying the centre mullion offering completely unrestricted space.


Safety & Compliance


French Casement windows are fully compliant with current Building Regulations and therefore ideal for smaller openings especially where a fire escape is required.


More Light


When the window is fully open there is no central mullion in the way, this allows the maximum amount of light to flood the room.




It is possible to open both vents fully or alternatively open the master sash independently to the slave for ventilation.

Flying mullion attached to master sash keeps the amount of plastic profile on show to a minimum.

Allows even smaller openings to be used as fully Building Regulations Part B. compliant fire escapes.
