What are casement windows?

A casement window is typically hinged at the side like a door and is usually fitted in single or double panels. Casement windows are often held open using a casement stay. Those windows that are hinged at the top are referred to as awning windows whereas those casement windows you find that are hinged at the bottom are called hoppers.

How do casement windows work?

Without sliding up or down or tilting or turning, casement windows have fixed hinges either at the side, allowing them to be opened outwards like a door, or at the top or the bottom. Fitted either singly or in pairs, they typically open using stainless steel friction hinges which help keep the window open for ventilation, without slamming shut during windier periods.

What types of casement windows are there?

There are several different types of casement windows including the following:

  • Single casement window: A single hinged window within a frame, typically opening similarly to a door with a handle known as a ‘casement fastener’.
  • Double casement window: These typically open outwards from the centre.
  • Flush casement window: Here, the sash sits flat and flush with the surrounding frame, offering sleek lines and a simple aesthetic. Flush windows became popular in the Edwardian era and are also a popular choice for contemporary properties because of their simple, elegant design.
  • Fixed casement window: These are windows that can’t be opened, for example, large static ‘feature’ windows. They allow natural light into a room and provide a clear view of the outdoors but provide no ventilation.
  • Awning casement window: These types of casement windows are installed horizontally, using hinges attached along the top of the frame. They open outward from the bottom, guaranteeing ventilation whilst also preventing rain from seeping in.
  • Hopper casement window: These are similar to awning casement windows in the sense that they are installed horizontally. However, hopper windows are positioned in the opposite direction, with the hinges along the bottom.

What materials are best for casement windows?

Casement windows are available in a wide range of materials, including aluminium, uPVC, and Timber. The choice of material depends on a variety of factors including your budget, style, insulation, durability, and sustainability preferences.

The use of wood for casement windows is the natural choice for period properties as it is the material the window would have originally been made with. It is the most sustainable and authentic choice and will help a property maintain its value, whilst being the most planet-friendly option.

In addition, due to advances in timber, it is now more long-lasting than ever and a low-maintenance option, with a good quality timber window lasting up to 100 years. Timber windows can also be easily maintained and repaired, unlike aluminium and uPVC windows.
