Types of Window
The first important thing to understand is that windows are usually defined according to how they open. The main part of the window is known as the "sash" and it is how you open the sash part of the window that determines what type of window it is. Here is a quick overview of the main types of window available.
A casement window is a window with a hinged sash that swings in or out like a door. They are usually side-hung but can also be hinged at the top (known as an "awning window").
The biggest advantage of a casement window is the fact that it can be fully opened and allow for superior ventilation. Casement windows can also be opened outwards, making them ideal for areas where internal space is limited. When combined with a doubled glazed unit, casement windows are also excellent in terms of energy efficiency and when combined with a secure locking system, they are second to none in terms of security.
One of the biggest drawbacks of casement windows is safety – especially if you have small children – as usually the whole sash opens, unlike a double-hung window that can be just opened at the top.
Tilt and turn windows
Tilt and turn windows provide excellent unspoilt views. They can be manufactured and operated much larger than a traditional casement window, so if you require an unobstructed panoramic view then these are the perfect choice for you. Another advantage of a tilt and turn mechanism is that in the tilt position it allows for ventilation but can be tilted according to how much of a draft you require alongside allowing easy access for cleaning.
Unfortunately curtains and blinds can prevent the full operation of a tilt and turn window so if you require privacy then these may not be the ideal choice. Also this style of window is more expensive and can be more expensive to repair.
Sliding sash windows
Sash windows consist of two window panes that overlap slightly and slide up and down inside a frame. Usually a weight is used as a counterbalance to facilitate the operation of sash windows.
Sash windows can be either “double-hung”
Sash windows suit traditional properties and are more in keeping with period properties such as Victorian or Georgian, so if you want an authentic feel for your home then these are the style to use. Although sash windows are not as secure or energy efficient as casement windows, more recently they have become available in UPVC allowing for a traditional appearance but constructed from a hard wearing energy efficient material.
A bay window is a set of windows that extend out from a property – often in a box shape that overhangs, projected outwards to create interior space. Bay windows allow for lots of different view points from one window, giving a panoramic view and can often create a feeling of space and add an extra dimension to a property.
One of the disadvantages of this style is that the main window is fixed and usually only the side windows or small top windows can be opened thus restricting ventilation. Also bay windows are more costly to fit and repair than a traditional casement or sliding sash window and are more suited to certain homes for example Victorian or period properties.
Hopefully this quick guide will help you understand the basic types of window available with the possible benefits of each style when you are buying new or replacement windows for your home.
