Awning windows pivot at the top and may have outward or inward-swinging sash; the most common is the outward-swinging sash. Awning windows are usually operated with a roto-gear or push-out lever so that the window can be adjusted to keep out rain but let in fresh air. This window type provides up to 50% ventilation area, as the hardware does not allow them to be fully opened.
Casement windows swing outward on side hinges. These windows can be hinged left or hinged right (as viewed from the outside) and are operated with a roto- gear and crank. Casement windows provide almost 100% ventilation area, because they can be fully opened and the out-swinging sash can direct plenty of air into the building.
Picture windows are fixed windows that do not open. They are used to let in a lot of light and to take advantage of a view. Picture windows are often used in combination with operating windows.
SINGLE TILT SLIDER
These windows have sash that slide horizontally. Single sliders have one fixed sash, while double sliders have two movable sash. Most horizontal sliders have at least one removable sash.
DOUBLE TILT SLIDER
These windows have sash that slide horizontally. Double sliders have two movable sash.
SINGLE HUNG WINDOWS
A single hung window is a vertical slider in which the top pane of glass is fixed and the bottom sash moves. In some designs, the sash tilts in for ease of cleaning.
DOUBLE HUNG WINDOWS
Double hung windows are similar to single hung windows, except that both sash move and are controlled by a balancing mechanism so the sash do not fall down when raised.
Bays windows projects outward from a building wall. A bay window has a fixed centre window parallel to the wall flanked by two operating windows (casement or double hung windows) attached at an angle (usually 45°).
Bow windows have more than three sections set at gentle angles (usually 10°) that give the window a curved appearance (like a bow).
Arched windows have rounded tops that add an architectural design to any home. The average cost for arched window installation is around $325 to $500 per window. Most arched windows do not open or close and are often installed above standard windows that provide ventilation. Some arched windows can open the same way a casement window does.
There are many shapes of windows now in use, including circles, half rounds, octagons, fans, and many other geometric shapes. These geometric shapes can be used alone or in combination with other windows. Custom windows can give a curved appearance to a building or can simply add charm and character to a room.
Garden windows look a bit like bay windows and the two are often mixed up as a result. The most obvious difference is how people use them. Garden windows are often furnished with plants, herbs, and flowers. But there is an aesthetic difference. Garden windows take on a different shape to their bay window cousins. Garden windows angle at 90-degrees to make a box-like shape. Garden windows aren’t usually as large as bay windows. Whereas bay windows can be large enough to sit in, garden windows have space only for plants and flowers.
