Commonly Asked Questions

  • +
    What are the different types of casement windows?

    There are several types of casement windows that generally differ in how the window opens:

    • Side hung - Hinged at the side is the most common type of casement window and the opener will swing outwards.
    • Single casement - The most basic window style has one frame and is usually side-hung.
    • Double frame or french casement - Two side-hung casement frames with handles in the middle that opens outwards to each side and create a large aperture (with central mullion).
    • Top hung or awning window - Hinged at the top of the frame the window swings outwards from the bottom. This style is perfect for wet climates as they stop rain from entering the room.
    • Bottom hung or hopper window - Hinged at the bottom of the frame the window drops open from the top of the frame. This allows plenty of ventilation and is a safer option for upper-floor windows.

    What is a flush casement window?

    A flush casement window is the same as a casement window except for how the window opener sits on the outside frame.


    A standard casement window opener sits proud from the frame when closed.


    A flush casement window opener sits flush into the frame when closed.


    The benefit of a flush casement is the enhanced weatherproofing and draughtproofing. But the flush casement gives a sleek appearance and is becoming very popular as a contemporary style when combined with a slim aluminium frame.

    Are casement windows the best type of window?

    Casement windows are incredibly versatile with so many different configurations. They can be styled traditionally, or contemporary with different materials, so they suit any type of property.


    The only limitation of a casement window is the size of the opening panel. Due to the weight of the glass, an opening panel hinge has to support the window so it can only be a certain size. This is why casement windows are configured with different-sized panels.

  • +
