According to the different window opening methods, they can be divided into three types: casement windows, top-hung windows and sliding windows. Different window opening methods have their own advantages and disadvantages. Then, you know which window opening method you like or are most suitable for. Each window method has its advantages and disadvantages. Today, the editor will explain the advantages and disadvantages of these three different window opening methods.
What are the advantages and disadvantages of casement windows, sliding windows and top-hung windows?
1. Sliding windows
Sliding windows are driven by external force acting on the window sash to realize the opening and closing of the window sash. According to the number of blades, they can be divided into single-leaf, double-leaf and multiple doors and windows that slide left and right. It is an economical and practical window.
(1) Advantages: Sliding windows are more simple and beautiful, with larger window sashes and higher daylighting rate. The position and vents of the windows can be selected relatively freely, and can be opened and closed in a plane that does not occupy the indoor space. It is more convenient to install and use curtains, which is the most commonly used installation method.
(2) Disadvantages: The two windows cannot be opened at the same time, and can only be opened half at most, and the ventilation is relatively poor.
2. Casement Window
A casement window is a window that uses a hinged sliding support (four-link, etc.) to connect the sash and frame, and uses a handle on the other side to open horizontally inside and outside or axially inside and outside.
(1) Advantages: When the casement window is closed and locked, the rubber sealing strip is compressed and elastically deformed in the sealing groove of the frame fan to form a complete sealing system with good thermal insulation, heat preservation, sealing and sound insulation performance. At the same time, the sash can be fully opened in the open state, and the ventilation performance is also very good.
(2) Disadvantages: However, since the fan and the frame are connected in a cantilever structure. Therefore, not only the cantilever effect of the weight of the entire sash including the glass must be considered, but also the wind load will be damaged when it is opened. In addition, the moment of inertia of the fan profile must be large, and the hardware components have high quality requirements. At the same time, when the inner casement window sash is opened, it will occupy part of the indoor space. The outer casement window is affected by the hardware quality, which will cause safety hazards to the outdoors and has a higher cost. It is suitable for buildings in cold and hot areas or buildings with special requirements for sealing and insulation. The building management departments in some areas have stipulated that the use of casement windows in high-rise buildings is prohibited.
3. Top-hung windows
Top-hung windows are hinged or hinged at the top of the window, and the window is pushed outward or the handle box is pulled to open the window; bottom-hung windows are the opposite, where the hinge or hinge is installed under the window and pushed outward or pushed. Open the window like pulling the internal handle. Both methods are new window opening methods developed on the basis of casement windows.
(1) Advantages: Because the top-hung windows have hinges, the window can be opened intelligently with a gap of about ten centimeters. People cannot enter from the outside. It is very safe for residents; this type of window fan takes up less space and is very suitable for places where the installation location is restricted, such as kitchens and bathrooms.
(2) Disadvantages: Due to the small opening that can be opened, the ventilation is not so strong.
