Side openers and Top openers (and a mixture of both) Casement windows
This are pretty self explanatory - one opens at the side the other from the top. They open outwards
Tilt n Turn
This windows have a single handle, but have two opening options. The window tilts inwards to allow ventilation through the top of the window, whilst also giving the option of an inward opening window - great if you have limited outside space. This also enables easy cleaning.
Vertical sliders/Sash
These windows can open from the top and bottom - either both panels slide up and down or open panel can be fixed.
French Windows
Much the same as French Doors this style enables the entire window to be opened with a floating Mullion. So you can have two side opening windows without a divide in the middle - these are particularly useful when ensuring you have an adequate means of escape.
Sidelights/ top-lights
Sidelights normally found either one side or both sides of a door and a top light can be above. This can be fixed or have openers (or a combination of both)
Sliding windows
The same principle as a set of patio doors but in a smaller form
Bay windows
Comes out from the main walls of the building with brickwork down to the floor
Bow Windows
Same as Bay but without the brickwork to the floor
