The quality of doors and windows is determined by a series of complete quality assurance systems. Therefore, the energy saving of building doors and windows must pay attention to the systematic engineering of each production link, and in particular fundamentally change the contempt for hardware. It can be said that the door and window hardware accessories are the "heart" of the doors and windows. As the composition of buildings, doors and windows directly affect the energy-saving performance of buildings, and improving the insulation performance of doors and windows is the main way to ensure the energy consumption of buildings.

The main ways of building energy consumption are as follows:
1: China's building energy consumption (including construction energy consumption and energy consumption) accounts for about 1/4 of total energy consumption
2: The energy consumption for building use accounts for more than 1/2 of the building energy consumption
3: The energy consumption for heating and air conditioning is about 1/2 of that for building use
4: According to the normal ratio, the area of ​​doors and windows accounts for more than 20% of the building area
5: From the perspective of energy loss, 50% of the energy loss of the entire building is lost through doors and windows.
A large amount of energy is lost through doors and windows, causing great waste. Therefore, China is strongly promoting energy-saving doors and windows. Therefore, if building doors and windows use unreasonable hardware or hardware, the airtight performance of the building doors and windows will be greatly reduced. The hardware accessories determine the sealing performance of the entire window. If there is no hardware, then the gap between the doors and windows The wasted energy waste will be an alarming figure.
Door and window hardware accessories are another key product of Jianlang, its characteristics are:
1: Easy to operate, single point control
2: Standardization and serialization
3: Adjustability
4: strong bearing capacity
5: High security
6: Wide range of applications
7: strong adaptability
8: High-quality specifications
