How to buy door and window hardware to make doors and windows more energy efficient

Hardware is a detail that consumers always ignore when purchasing doors and windows. Doors and windows cannot be separated from hardware. Without hardware, all functions of doors and windows cannot be realized. So what impact will hardware have on doors and windows? Although the hardware will not directly increase the energy-saving coefficient of doors and windows, it will directly affect the energy-saving effect of doors and windows.

Hardware witnessed the development history of doors and windows
Architecture doors and windows have a long history in China, and records about the version doors can be found in some unearthed Shang dynasty bronzes. It is used for city gates or gates of palaces, temples, and houses, usually two. Mullion windows developed from doors have appeared in Han, and windows are fixed and cannot be opened, so functions and types of doors and windows are limited. At that time, the movable part of the door and window used a wooden shaft, as the idiom said: the hinge is not dù—the door shaft that is always rotating will not be moth-eaten, and no metal parts have been used.
During the Ming and Qing Dynasties, windows had a great development in type and appearance. More and more windows were opened and closed, and metal hinges began to be applied to doors and windows. China's modern architecture doors and windows were developed from the introduction of steel doors and windows in China in the early twentieth century, from the beginning of steel doors and windows to aluminum alloy doors and windows in the 1970s and 1980s, to plastic doors and windows in the 1990s, and then to the current situation.
Hardware is produced after the development of doors and windows to a certain stage. The realization of the functions of modern building doors and windows requires hardware to support it. Modern doors and windows have more and more functions, and more and more materials are needed. The basic materials are profiles, sealing strips, glass, insulation strips, handles and opening systems, etc., which form the door and window system.
How hardware can improve the energy-saving effect of doors and windows
I must adapt to local conditions. The application of different doors and windows should be comprehensively considered according to the area where the building is located, the functions of doors and windows. For example: doors and windows with better thermal insulation properties are used in the north; doors and windows with better sunshade and waterproof performance are used in the south.
Different regions have different requirements for door and window functions. The south generally needs heat insulation, and the north generally needs heat insulation. In addition, there are many storms in the south, and the waterproof performance of doors and windows is also required.
Improving the energy efficiency of doors and windows must first improve the quality of the doors and windows themselves. It is necessary to improve the energy-saving design indicators of doors and windows, strengthen the heat preservation and heat insulation performance of door and window materials; improve the structure of doors and windows (double-layer, multilayer glass, internal and external shading systems); and improve the air-tight performance of doors and windows through structural design, manufacturing and installation.
The core is to improve the sealing performance of doors and windows. Improving the sealing performance depends on the sealing rubber strips. The window sash and the window frame press the sealing rubber strips to achieve the sealing effect. The combination of lock point and lock block can improve the sealing performance of doors and windows. The more lock points of doors and windows, the better the sealing performance. Of course, the premise is that other materials of doors and windows are of high quality. Under the same quality, multi-point locks are better than single-point locks.
The design of doors and windows can not only consider the material, but also the deformation of the profile and the elasticity of the sealing rubber strip. Doors and windows with a single point lock will only improve the sealing performance on the side with the lock point. Good sealing effect. Therefore, good materials may not achieve good sealing effects, and must be used with high-quality hardware.
German hardware is currently recognized as the best quality door and window hardware in the world, such as Germany's Mtuosi door and window hardware, allowing owners to rest assured and comfortable in the purchase of doors and windows.
