It has the characteristics of light, light, environment friendly, durable, light and durable.
However, the poor thermal insulation performance of its frame material affects the performance of aluminum doors and windows. Therefore, improving its thermal insulation and energy-saving performance is the key technical problem to be solved in the future, and it is also the development direction of Lifen. Improved structural design.
In order to improve the performance and grade of existing doors and windows, it is necessary to improve the structural design. Instead of the low-level structure which only pursues labor-saving, material saving and low-cost in the past, it is necessary to realize the transition from the aluminum alloy sliding window to the aluminum alloy casement window with better performance, and realize the diversified system design of single-layer, double-layer, three-layer and small opening and large-scale fixation.
Why is the thermal insulation performance of Livan aluminum alloy doors and windows good? Focus on the choice of raw materials
The general requirements of frame materials should be good strength, good heat insulation performance, easy to make into various shapes, easy to recycle and conducive to environmental protection. In order to improve the thermal insulation performance of aluminum alloy window frame, it is better to make the broken bridge or composite type.
(2) insulating glass should be widely used in glass, and Low-E insulating glass should be popularized in North China. In the south of China, the use of solar coated glass should be promoted. Single glass and white glass are no longer used in developed countries because they are not conducive to energy conservation and improvement of living environment.
(3) promote the use of double seal and insulating glass made of polysulfide insulating glass glue. The insulating glass spacer should be of continuous curved angle structure. If the four corner plug-in type is used, butyl rubber must be used for sealing treatment at the joint. Single seal insulating glass is not available, and silicone structural adhesive used as secondary sealing insulating glass is not recommended, because their service life is relatively short.
