What is window friction hinge and how to chose?

For a window, the window friction hinge supporting and connect the window, the handle is a switch, control the window opening and closing; the hinge is its spine, connect the window and window frame; 

In fact, the window friction hinge can be subdivided into window friction stay (hinge) and window limited stay(support arm) ; the two styles are suitable for different window structure, there are some differences between friction stay and limited stay, but today we are going to focus on introducing the window friction hinge;

What is window friction hinge?

The window friction hinge is made of stainless steel, which is mainly used to connect the window sash to the window frame and act as a bridge. It can make the window open and close smoothly, The components of window friction hinge generally have slide rail, slider, bracket, long cantilever, short cantilever and oblique cantilever, the slider is installed on the bottom groove, long cantilever hinged between the slide rail and bracket, short cantilever hinged between the slider and bracket, oblique cantilever hinged between the slider and long cantilever. Besides, the window friction hinge has limited the position of the window sash, its max opening angle is 0-90 degree for side-hung and 0-40 degree for top-hung window.

the introduction and application of window friction hinge 

There are two kinds of similar appearance, but not the same performance of friction hinge. One is for side-hung window, this type of hinge is always called four link bar hinge; it not only has the same limit positioning function with the window limited stay, but also can bear the weight of the window sash;and the other friction hinge is for top hung , applied to the hanging window curtain wall, this kind of window friction hinge is mainly played the role of bearing the weight of the window sash for top-hung windows.

The window friction hinge is installed on the upper and lower sides of the sash to support and connect the window sash and control the opening Angle. From the performance and application, they are have differences, and when choose the friction needs to be considered the actual situation.

How to choose a window friction hinge?

For window hardware accessories choosing, It is according to the dimension of window sash, structure, weight to choose a appropriate window hardware accessories,the same as friction hinge; Why do we need to explain the selection method of window friction hinge? Because if the window friction hinge selection is not good, it will make the window sash open and close not smooth, but also may leak and noise, thereby shortening the service life of the window, so it is necessary to learn to choose the window friction hinge;

1, the window sash width is relatively large, it is recommended to choose the friction stay occupying two-thirds of the window width;

2, if the weight of the window is relatively light, it is recommended to choose the window friction hinge occupying half of the window width;

3. If it is used as friction hinge for top-hung window, it is generally matched with a friction hinge of half the height of the window.

According to the above detailed introduction and sharing, I believe that we can recognize what is window friction hinge and well choose the right window friction hinge for ourselves. It is very useful to make clear the daily use of the window friction hinge.
