What are Casement Windows?

Casement windows are the most contemporary and convenient of all window types. A casement window is attached to a frame by one or more hinges and either a manual (or automatic) mechanism which cranks the window outwards, away from the home.

The casement window has many different configurations; the openers can be top or side hung or even fixed. The most recognisable casement is the side hung which is hinged at the side for easy opening.

The top hung or awning casement window is hinged at the top which is perfect for wet climates as it blocks out rain. Conversely, the bottom hung casement window is hinged at the bottom and is commonly used in basements.

Advantages of Casement Windows

Versatile

When it comes to home improvements, casement windows are a popular choice as they are versatile and can be designed to suit virtually any style of property in uPVC, timber or aluminium frames. They can be tailored to suit precise sizes and in a variety of colour finishes to suit any home’s aesthetic.

Fully sealed for insulation

Fixed pane windows obviously offer the best level of insulation and energy efficiency, but casement windows aren’t far behind. All casement windows are fully sealed as the window sash presses against the frame to create an airtight seal when closed. This helps prevent cold air getting in and warm air getting out, improving the energy efficiency of a home and reducing heat loss which should save you money on energy bills.

Simple to use

They are easy to open and close and due to their configuration and many can even be installed alongside automatic openers.

Clear views

Casement windows give an unobstructed view when open and when closed, plus they allow a lot of light into any room.

Ventilation options

Unlike double hung windows casement windows are open top to bottom and can be opened all the way out for maximum ventilation. However, they can also be angled slightly to catch breezes, helping to circulate air around the house.

Security

Double glazed casement windows offer superior insulation and security.

Disadvantages of Casement Windows

Limited in size

Casement windows need to be able to opened outwards so the frame needs to be able to be support the weight of the window. This may limit the size of window you can have in terms of both dimensions and weight.

Not compatible with screens or storm windows

Because these windows open outwards you won’t be able to put a screen or storm window on the outside.

Types of Casement Windows

There are 3 main types of casement window:

  • Single frame casement windows are the most commonly installed. These windows have a single frame. Inside the frame are panels of glass are separated by wooden strips. They open outwards or inwards, depending on how they’re mounted.
  • Double casement windows used to be known as French casement windows. These are two windows hinged on the sides that swing out and meet in the middle.
  • Push-out casement windows come in both single and double styles and are operated by a handle rather than a crank.
  • Casement Window Prices

    Typically, the average price of a casement uPVC window with 1 opener will range from £250 – £400. Obviously, the prices will vary according to the materials and the added extras.

    Here are some estimated figures based on industry research for you to use as a guideline:

    Size of Window (mm) Style Price per window (not including installation)
    500 x 500 Fixed £150 – £200
    1000 x 1000 Fixed £200 – £250
    1200 x 1200 Fixed £250 – £300
    500 x 500 1 Opener £250 – £300
    1000 x 1000 1 Opener £275 – £325
    1200 x 1200 1 Opener £350 – £400
    500 x 500 French £450 – £500
    1000 x 1000 French £500 – £550
    1200 x 1200 French £525 – £575

     

    • Wood effect uPVC frames will cost around 15-20% more than plain white frames.
    • Aluminium frames cost 30-50% more than white uPVC frames.
    • Timber framed casement windows costs depends on the nature of the wood and will increase the budget by roughly the same 30-50% as aluminium windows.
    • Single casement windows tend to be less expensive than double ones, because they have only one component, while push-out windows are the least expensive because they don’t have cranking handles.
