Opening Method Of Casement Windows

The advantages are simplicity, aesthetics, large window width, large glass blocks, wide field of view, high lighting efficiency, convenient glass cleaning, flexible use, safety and reliability, long service life, opening in one plane, occupying less space, and convenient installation of screen windows. The most commonly used is the sliding window. The disadvantage is that two windows cannot be opened at the same time, only half can be opened at most, and the ventilation is relatively poor; Sometimes the sealing performance is also slightly poor.
Overhanging type
This is a type of aluminum alloy and plastic steel window that only emerged later. It is a new form developed on the basis of casement windows. It has two opening methods, which can be opened horizontally or pushed from the bottom. When a casement window is closed, pushing the lower part of the window outward can open a gap of about ten centimeters. That is to say, the window can be opened a little from below, and the open part is suspended in the air, connected and fixed to the window frame through hinges, etc., so it is called an upward hanging type. Its advantages are that it can both ventilate and ensure safety. Due to its hinges, the window can only open a ten centimeter gap and cannot be reached by hand from outside, making it particularly suitable for use when there is no one at home. This function is no longer limited to horizontally open windows, but sliding windows can also be opened in an upward hanging manner.
