First, doors and windows are lightweight components, the use of energy consumption accounts for about half of building energy consumption is the most important building energy efficiency, in the design of windows and doors to give full consideration to the energy-saving issues, namely, insulation and insulation. If there is no multi-point door and window hardware accessories, doors and windows to do even the best, the insulation, insulation can be imagined.

 

Second, the same, doors and windows of the property owners are also most concerned about security issues. In this regard, the doors and windows hardware accessories anti-theft performance, especially in the development of intelligent anti-theft doors and windows in the component is playing an important role.

 

Third, the physical properties of doors and windows are: anti-wind pressure, air tightness, water tightness, insulation, insulation, sound insulation, wind pressure. When the flat window is being wind pressure; hardware lock point force, it is appropriate to adopt a multi-point form. The more the lock point, the role of each lock point to the very small force, the deformation is relatively small deflection. When the negative pressure inside the window by the window: the box force. When the outer flat window pressure: the lock point force, it should adopt the form of multi-lock point. The more the lock point, the role of each lock point to the very small force, the deformation is relatively small deflection. When the outer window by the positive pressure: the frame force. Doors and windows can be seen more than the hardware performance of the doors and windows of the first performance of the role of wind pressure performance, determines the success of doors and windows; the same, air tightness, watertightness, insulation, insulation, sound insulation and doors and windows hardware accessories Of the doors and windows sealed. Door and window hardware accessories lock points and lock blocks distributed around the doors and windows. When the doors and windows are locked, the lock points, lock seat firmly buckle together, and the hinge (hinge) or sliding support for the same with a strong sealing force, the elastic deformation of the seal, which provides adequate doors and windows Of the sealing performance, so that the fan, the box can be greatly integrated to improve the performance of doors and windows. Similarly, doors and windows fold mechanical performance (opening and closing force, repeated opening and closing), such as opening and closing requirements can not be separated from the requirements of doors and windows hardware accessories.

 

Fourth, windows and doors have a variety of window-shaped and structural forms, and all the various functions of window-type windows and doors hardware accessories dependent on the configuration. Just think, no doors and windows hardware accessories, flat open under the hanging window how to achieve both open and inverted function? Push and pull folding doors and windows and how to achieve both push and pull function of the folding it, push down the activities, such as shutters, which is not by Door and window hardware accessories to achieve its unique function? It can be said that doors and windows hardware accessories are windows and doors accessories "heart."

 

Door and window hardware accessories for doors and windows with insulation and many other features. So the doors and windows hardware in the windows and doors can not be ignored, if you buy windows and doors, do not ask how the quality of doors and windows, you should be concerned about the hardware accessories doors and windows. Building windows and doors must be able to open and close, to achieve ventilation, ventilation, insulation, insulation, sound insulation, weatherproof and other functions, therefore, requires building windows and doors in a certain wind and wind and rain weather conditions, but also with wind Pressure performance, and construction doors and windows closed after the realization of the locking function of the components is the doors and windows hardware, such as the doors and windows in the open to withstand positive pressure, outside the doors and windows in the bear negative pressure, the doors and windows to bear the wind load completely passed to the hardware, And then by the hardware will be transmitted to the wind load on the door and window frames and building structures, so that the doors and windows hardware is the impact of building windows and doors of the main features of wind pressure performance components.
