The inner louver glass is installed in the inner cavity of the hollow glass. Through the magnetic control of the sealed cavity of the hollow glass, the inner louver glass can be put in and turned over, so as to achieve the function of shading and dimming. The technology has been widely used in architectural sunshade integrated exterior window products due to its superior performance. Double handle built-in shutter hollow glass technology of jiangsu cheng, Shanghai's domestic well-known enterprises such as joy, jiangsu sadie joy, at home and abroad, widely used in building integrated shading Windows and indoor partition, especially in our country in recent years, the all-round development of energy-efficient building and green building, and more used in high performance window sunshade integration the double handle built-in shutter hollow glass technology. A large number of engineering examples and test data of research testing institutions show that the safety reliability, quality durability, operation convenience and decorative beauty of the built-in louver hollow glass with double handle are obvious, which has been highly praised by industry experts and application customers.

Though the double handle built-in shutter hollow glass technology relatively complex (need to increase the magnetic block, handles and other important components), costs a bit more, but with double handle built-in shutter hollow glass is excellent performance is more and more market and user recognition, its application in engineering high performance-to-price ratio also got more attention.

1. Safety and reliability

Double handle built-in louver insulating glass -- with double safety and stability, specific performance in: the inverted system and the retracting and releasing system *** vertical setting, respectively control, so that the curtain disc retracting and releasing drive force reduced, more stable and reliable operation; Among the large-sided built-in louver insulating glass products, the single curtain area of a single piece of glass product can be controlled freely even if it achieves 3.8m. Due to the balanced distribution of torque and tension of the transmission device, the safety and reliability of double-handle built-in louver glass products are greatly improved. The failure rate of double-handle built-in louver glass products is less than 2%, which is 5 times lower than that of single-handle built-in louver glass products.

Louver insulating glass built in single handle -- due to its own technical limitations, the curtain is crossed in the two actions of retracting and retracting, frequent closure and repeated friction, which easily leads to the deformation and blackening of the aluminum curtain, the wear of the drawstring and the failure of the lifting system. Curtain in the process of lifting must go through 2 close, can be folded or spread, accelerated the wear of ladder rope, pull rope easy to cut; When the curtain roll over, put in a transmission system, increase the load of a single transmission, easy to make the transmission device failure. On the market, it is difficult to ensure the product quality if the area of a single glass product with a single handle is 1.5m. Problems such as control failure and demagnetization often occur, which cannot meet the requirements of many glass sizes for the whole building.

2. Convenient operation

Double-handle built-in louver insulating glass -- the double-slide can be turned over and switch independently set in the upper, middle and lower positions of the glass side. The lifting stroke of the handle is only half of the total glass height. The user-friendly operation height makes the user accessible, convenient and comfortable.

Single handle built-in louver hollow glass -- when the curtain plate is down, the handle is in a high position, the lifting stroke of the handle is far more than half of the total glass height, even reach a 1:1 stroke, difficult to control, not suitable for housewives, old people and children to use.

3. Quality durability

Double handle built-in shutter hollow glass - double slide adjustable glass in the center of the vertical installation, to avoid glass appear skewed, ensure the long-term vertical transmission system running smoothly, double handle and release function set apart, it fell by 75%, and handle the use of frequency flip the handle use frequency decreased by 50%, setting down and make sure the flip use meet the requirements of 60000 and 100000, respectively, compared with the same specifications of the single handle built-in shutter hollow glass to extend the service life of 3-5 times.

Single handle built-in louver insulating glass -- due to increase the friction force, the synchronous belt type transmission mode is adopted, the following problems often occur in the application: A. Fatigue fracture of belt body and longitudinal crack of belt; B. Tooth fracture, wear, cloth stripping; C. The extension pitch of the bearing layer increases, resulting in tooth climbing; D. Frequent problem cases and high repair rate in engineering projects, the European and American international markets have long been replaced by the second generation of louver glass for the rope drive system in 2003.

4. Beautiful decoration

Double handle built-in louver insulating glass -- double handle double track visual symmetry, glass products square and beautiful, in line with the aesthetic habits of ordinary people.

Single handle built-in louver hollow glass -- single handle 7 side frame ratio imbalance affect the beauty, not in line with relevant national standards and ordinary people's aesthetic habits.
