With the continuous development of aluminum alloy doors and windows industry, aluminum alloy doors and windows are widely used in sunlight room, large-scale engineering, factory construction, home decoration and other aspects. Energy saving and environmental protection of doors and windows is the goal pursued by many enterprises. Under the promotion of the national "energy conservation and emission reduction" policy, it has become the mainstream consumer products
Aluminum alloy doors and windows have the characteristics of good performance, light weight, beautiful, good lighting, durable, easy to recycle and reuse profiles, no environmental pollution and so on. However, the performance of the thermal insulation material of the aluminum door and window is poor.
In order to save energy, we should improve the performance of aluminum alloy doors and windows
Improving structural design
In order to improve the performance and grade of the 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 transformation from push-pull window to better performance
Good casement window is the main transition to realize the diversified system design of single-layer, double-layer, three-layer and small open large fixed system.
Pay attention to the choice of raw materials
① 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 popularized for glass, and Low-E insulating glass should be used 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 Double seal and insulating glass made of polysulfide insulating glass glue should be popularized. 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.
