1 Introduction
Casement window
The opening and closing of window sashes move along a certain horizontal direction, so it is called "swing window".
Casement windows are divided into push-pull type and top-hung type. Its advantages are large opening area, good ventilation, good airtightness, sound insulation, heat preservation and impermeability. The inward opening type is convenient for cleaning windows; the outward opening type does not take up space when opening. The disadvantage is that the window is small and the field of view is not wide.
Opening windows outside the wall takes up a space outside the wall and is easily damaged when strong winds blow; and windows opening inside takes up part of the indoor space. It is inconvenient to use screens, and it is inconvenient to use screens and curtains when opening windows. If the quality is not good enough, there may be rain.
2. How to open
a. Sliding window
The advantages are simple, beautiful, large window width, large glass blocks, wide field of vision, high daylighting rate, convenient glass cleaning, flexible use, safety and reliability, long service life, opening in a plane, less space, and convenient installation of screens. The most popular one is the sliding window. The disadvantage is that the two windows cannot be opened at the same time, at most they can only be opened halfway, and the ventilation is relatively poor; sometimes the airtightness is also slightly poor.
b. Top suspension
It is a new form developed on the basis of casement windows. It has two opening methods, which can be opened horizontally or pushed away from the bottom. When the casement window is closed, push the lower part of the window outward to open a gap of about ten centimeters. In other words, the window can be opened a little from below, and the opened part is suspended in the air and fixed with the window frame by hinges, etc. Known as the top suspension. Its advantages are: it can be ventilated, but also can ensure safety. Because of the hinges, the windows can only be opened with a seam of ten centimeters, which cannot be reached from the outside. It is especially suitable for use when there is no one at home. This function is not only limited to casement windows, sliding windows can also be opened up-hung.
