Are the hinges of UPVC awning windows installed inside or outside the window frame?

There is no fixed answer for the hinge installation position of UPVC awning windows, as it depends on various factors including window design, usage requirements, installation environment, and aesthetics.
Generally speaking, the installation position of hinges can be inside or outside the window frame. Specifically:
If the window is designed as an inward opening, hinges are usually installed inside the window frame to ensure that the window can smoothly open and close inward.
If the window is designed as an outward opening, or if external factors such as wind force need to be taken into account, hinges may be installed on the outside of the window frame to increase the stability and safety of the window.
In addition, the installation environment is also an important factor in determining the position of hinge installation. For example, if a window is installed outdoors and is often eroded by natural factors such as rain and sunlight, installing hinges inside the window frame may be more beneficial in protecting it from damage.
When deciding on the installation position of the hinge, aesthetics also need to be considered. Some beautifully designed UPVC awning windows may hide the hinges inside the window frame or use other methods to make them less conspicuous, in order to conform to the overall decoration style.
In summary, the hinge installation position of UPVC awning windows should be selected according to specific circumstances. Before installation, it is recommended to consult professional door and window installers or designers for more accurate advice and solutions. At the same time, whether the hinge is installed inside or outside the window frame, it is necessary to ensure a firm and stable installation, and regular maintenance and inspection to ensure its normal use and extend its service life.
