Types of House Windows
Quality double glazed windows in Perth, Western Australia.
Windows revitalize the appearance of a house, however, it takes the right window type, size and arrangement that fits to the face of the building. Different window types can brighten the facade and individualise the look of a house. Different types of windows can also have significant influence on the internal atmosphere of a house.
They are among the most effective architectural design elements and can meet several requirements and desires.
Window designs can be divided into four groups.
Construction Types and Functionality
Comparison of the basic window types
Fixed Windows – are fixed as the name says. Fixed Windows are a less expensive option compared to other types of house windows. Some windows of a house get very rarely or never opened, if that is known in advance then the use of fixed windows or doors can reduce the costs of a building. Usually fixed windows are more durable because they have no wear parts and more energy-efficient because they are always tightly closed. However, one should remember that the outside of fixed windows can be cleaned from the outside only.
Awning Windows – are hinged at the top and open outwards. Awning window styles vary slightly, some wind out and some simply push open. Awning windows allow ventilation during rain and offer protection from entering the house through the windows even in opened state. A common disadvantage of awning windows is that they usually cannot be opened fully. In an emergency situation the window could be the last exit of a room – imagine such a situation and you can’t open the window wide enough.
Casement Windows – swing horizontally and are hinged at the side. Optionally casement windows can open outwards or inwards and are usually easy to handle. The window sash of casement windows is normally fully openable and thus allows good ventilation. A security disadvantage of casement windows is however, that they are either locked or open. In other words, an opened casement window is always a potential way for somebody to enter the house from outside.
Double Hung Windows – are basically two window halves which move up or down within the frame. A double hung window has two sashes, an upper sash and a lower sash, positioned one over the other and can be opened to allow ventilation from the top or bottom. It is probably the beauty of this type of house windows that makes them so popular. Double hung windows have no disturbing window sash, which opens to the inside or outside. The functionality of a double hung window looks more like a rotated sliding window. However, usually double hung windows require more force to open and close.
Sliding Doors or Windows – open to the side. Smaller sliding windows actually slide on tracks and bigger windows and doors are supported by wheels to make it more comfortable to open and close them. The weight of wheel based sliding windows is often supported by a top rail and the bottom tracks are only for guidance. The advantages of sliding windows are similar to double hung windows. A common disadvantage is however that they usually close less tight as other types of house windows and are hence less energy-efficient.
Tilt and Turn Windows and Doors – are very efficient window systems. Tilt and turn windows provide a dual opening function. They can be tilted slightly inwards to allow gentle ventilation even during rain and the sash can be turned (opened) horizontally like a casement window. A multi-locking system locks all four sides of the tilt and turn window and makes it very secure against unauthorised opening. The tilt function of tilt and turn windows allows air ventilation similar to an awning window and is still very secure against unauthorized entering of the house through the window. Tilt and turn windows combine all advantages of casement windows and awning windows, are in one grip easy to open or to lock and in combination with quality double glazing, they are exceptional energy-efficient.
