The innovation laboratory under China National Building Materials Group recently released a new generation of "honeycomb structure aluminum alloy doors and windows", breaking through the limitations of traditional profile technology and creating three major technological innovations:
Aerospace-grade lightweight: using bionic honeycomb aluminum design, while ensuring that the wind pressure resistance level reaches level 9 (the highest national standard), the unit weight is reduced by 40%, significantly reducing the load on high-rise buildings;
Intelligent thermal management: Phase change energy storage materials are implanted in the hollow layer of doors and windows, reflecting 90% of solar radiation heat in summer and increasing insulation efficiency by 35% in winter, and obtaining German PHI passive house certification;
Circular economy model: jointly with ALI Cloud to build a "door and window life cycle management platform", users can trace the source of materials by scanning the code, and the recycling and remanufacturing rate of old windows has exceeded 85%.
The product has been tested in the zero-carbon demonstration area of the Asian Games Village in Hangzhou. The data shows that compared with traditional aluminum alloy doors and windows, the annual air conditioning energy consumption is reduced by 22%, and the sound insulation performance is 42 decibels (increased by 18%). According to industry estimates, if it is promoted nationwide, it can reduce carbon emissions in the construction sector by more than 8 million tons per year.
Differentiation highlights:
Technology cross-border: integration of bionics, aerospace materials, and Internet of Things technology
Pain point solution: solving the contradiction between the load-bearing limit of high-rise buildings and energy-saving standards
Data endorsement: actual measured data such as load/energy consumption/sound insulation are benchmarked against international standards
