    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 are therefore ideal for smaller
    openings especially where a fire escape is required.

  • More Light

    When the window is fully open there

    to flood the room.

    French Casement windows provide
    totally unobstructed views and the assurance of being large enough to double as a
    fire escape for the home, office or building.

Features & Benefits

A flying mullion attached to the master sash keeps the amount of plastic profile on show to a minimum, this allows even smaller openings to be used as fully Building Regulations Part B. compliant fire escapes. Our French Casement windows can also be fitted with optional “Easy Clean” hinges for fast and hassle-free window cleaning and maintenance.
