Building energy saving and green building is a systematic engineering. The selection of materials and construction technology of energy saving and environmental protection also play an important role in the promotion of building energy saving and green building.
The quality of building doors and Windows with performance evaluation, can be summed up into four categories: security, energy saving, applicability and durability. What are the performance metrics associated with applicability? Water tightness, lighting performance, opening and closing force, and of course, air sound insulation performance. After 50 years of industrialization of doors and Windows, applicability is basically not considered as a key point. With the promotion of prefabricated buildings and passive buildings, high-performance soundproof doors and Windows will be widely used.
The role and status of the door and window system in the whole building has been significantly improved, but many important functions of the door and window system are realized by hardware fittings. In the field of door and window accessories, the traditional aluminum alloy window upper and lower hinge parts are exposed, which need to be cut when installing, and affect the overall appearance after closing the window, which cannot meet the needs of modern energy saving, environmental protection and low-carbon life.
Therefore, the door and window curtain wall industry, as a lip and teeth dependent on the building, is a key link to meet the refined needs of today's users and to form a system with prefabricated buildings. The door and window system, which accounts for 40% of building energy consumption, not only needs energy-saving and environment-friendly high-quality door and window products, but also needs high-quality hardware accessories and hardware systems to realize the important mission of green development of the door and window industry.
