Basics about European casement windows

Crank windows, crank out windows, roll out windows

These 3 names mean the same thing. That`s the typical American casement window operating with a crank. If you want to open such a window, you use the handle on the bottom of a window and turn a crank like a window in a Dodge Charger from 1970.

Casement (outwards) windows

In the American version casement window means the same as crank windows. But the operating way differs from European casement windows. 

An American casement window has a lockdown at the bottom. It has a handle that you crank to open up the window. 

In Europe, outward-opening casement windows are operated with handles and can have hinges on the left, right, or top. They are the most popular in the UK. Both types can go all the way to 90 degrees.

Casement (inward) windows, tilt and turn windows

The most popular version of casement windows in Europe. They open inward with a handle. The handle is integrated with high-quality hardware, so the whole system is safe and easy to use. They are also called tilt and turn windows, because by turning the handle 90° you open them widely and with another 90° (up / 180° in total) you open it on the top, creating ventilation. 

Inswing windows

This name is used by some American producers. Marvin casement window can open into a room. Marvin says it`s a good choice when an outswing window could block or take up valuable space on patios, decks or outdoor walkways. Although the inswing window opens inward, the technology of hardware is less advanced and less safe than in those from Europe. The handle is in a basic version and you cannot open it from the top to ventilate.

How casement windows work

A type of window known as a casement window is attached to its frame by hinges on one side and can swing outward to the left or right. You can associate it with how the door is opened. It can be opened and closed with either a crank or a handle. 

An American casement window has a lock down at the bottom. It has a llittle handle that you crank to open up the window. 

With European casement window you dont need to turn a crank, you just use a handle to open them or create ventilation from the top. Ventilation option is not available in the American version. If you want to know how to operate European tilt turn windows, check the video.

Casement vs awning windows 

In the U.S. the main difference between casement and awning windows is the positioning of the hinged side. Casement windows have hinges on either the left or right side, whereas awning windows have hinges at the top. 

But beware of a potential misunderstanding! In Europe there is no separate name for awnings. European awning windows are called just casement windows, because in Europe they have hinges on the left, right, or top. Watch the examples of European casements.
