This is a quick guide to the different window types common in the UK. They vary from complex and bespoke designs to simple and functional. Some windows look different but are all the same type, as they have different designs. Knowing your windows can be helpful when it comes to choosing new ones.
Learning what windows you currently have, means it’s easier to shop for like-for-like replacements. The same goes if you see a window type you really love, if you know what it’s called, you can search for one of your own.
Casement Windows
First let’s look at one of the most common type of window. Casement windows are so popular because they are very versatile. The main feature of a casement window is that it opens on hinges at the side or top which means it can be used in a variety of designs. In the image you can see that each window opens with hinges on the side. This can also be applied to smaller windows with hinges at the top. Single windows and windows with lines on (decorative additions known as Grilles or Grids) are still casement windows if they have the simple hinge opening feature.
Bay and Bow Windows
These two window types may sound similar but are actually different. A bay window projects out of the home with a wall, therefore providing a bit more floorspace. Bay windows have side and front facing windows, similar to Bow windows. The difference between them is Bow windows do not extend out of the house with the wall and give extra floor space. Only the window protrudes, and therefore may have a larger than average sill, with supports connected to the exterior wall.
Some might say that Bow windows have more sides and panes than Bay windows but that can change depending on the architect’s preference.
Sash Windows
Sash windows are usually seen on period properties and are either two panes that slide up and down, or one fixed pane and one sliding pane. They can add a lot of value to a property however timber sash windows do not age well. A lot of the time they are painted shut or become difficult to open and close. New sash windows look stunning and are built to last so they are an excellent choice for older properties.
Tilt and Turn Windows
This innovative window type is fairly unique because the window opens inwards and opens two different ways. The ‘tilt’ releases on a hinge at the bottom of the frame. This opens the top and allows airflow without letting the rain in. The ‘turn’ switches the window to open fully, using a hinge on the side. Opening inwards means the windows can be cleaned easily, a superb idea. This versatility means the Tilt and Turn window is a popular choice for homes.
Skylights Windows
Skylights are installed on roofs to allow light and fresh air in from above. Particularly helpful in loft spaces, skylights are increasingly popular on single storey extensions. Skylights tend to open with a mechanism in the middle of each side. When opened, one end of the window sticks out. This is one window you definitely want to make sure is closed when it rains but they are brilliant for views of the night sky.
Sliding Windows
Sliding windows work a bit like mini patio doors. They slide to the right or left but do not open outwards or inwards. This can make them impossible to clean from inside a room but are very handy if there isn’t much space around the window.
Transom Windows
Transom windows are the small panes of glass above doors. They can be inside or on external doors and were a way of producing airflow around a house before central heating. Transom windows also provided extra light in the days before electricity. They are not usually included in modern houses but if you have them, they are nice options for decorative glass and can be installed able to open, or fixed closed.
Now you know how to recognise these eight common window types:
- Casement
- Bay
- Bow
- Sash
- Tilt & Turn
- Skylights
- Sliding
- Transom
