Why Have Dormer Windows
Dormer windows, from the French ‘dormir’ meaning to sleep, have become a very popular style of window simply because they are so useful. In rooms where there may not be much head space they create a wonderful space as well as let more light in.
A dormer window is vertical and has its very own roof. Size and position plays a huge part in ensuring the dormer looks magnificent. If positioned badly, or if too big, the window can look terrible. Many architects install dormer windows as a means of putting ‘rooms in the roof’, and they are particularly good in houses that are not two full storeys high.
Create More Space with Dormer Windows
Domer windows are predominantly used to create space in the roof of a building. They do this by adding extra headroom and the space for additional windows. Dormer windows are one of the most prominent elements when a loft conversion takes place.
The term ‘dormer window’ is used to describe a window which has been set back into the dormer. Skylights are a good example of this; as the dormer windows let in a lot of light and act as a good source of ventilation.
A false dormer, also known as a blind dormer is a window which can only be seen from the outside of the house. This means that it is roofed off on the inside and therefore does not add any extra space or light to the room. Often, these are used for show, in order to make a property look more impressive, rather than providing a function.
Different Types of Dormer
There are many different types of dormer window to choose from, including the following:
• Gable fronted dormer: Where the front of the dormer rises to a point at the ridge of the dormer roof. This is also known as a dog-house dormer.
• Hipped roof dormer: When the roof slopes back from front of structure to a point farther back.
• Flat roof dormer: Where the roof of the dormer is flat.
• Shed dormer: A dormer (window) whose eave line is parallel to the main roof eave line. Eyebrow or eyelid dormer “A low dormer on the slope of a roof. It has no sides, the roofing being carried over it in a wavy line.” [3] The bottom of an eyebrow dormer is flat and the top is curved.
• Bonnetted Dormer. Arched roof of dormer, rounded shape when viewed from front. Popular in Victorian homes, especially in certain areas, like the Southcott-style row-houses called Jellybean Row in St. John’s, Newfoundland
