The durability of system doors and windows relies on the joint support of structural design, material selection, and craftsmanship. The injection process of corner pins, integrated welding sealing strips, specialized anti-corrosion hardware, and weather resistant structural sealing materials jointly reduce the risks of leakage, deformation, and aging, and extend the service life of doors and windows. High rise residential buildings have strict safety requirements for wind pressure resistance and fall prevention of doors and windows. The locking point layout, glass fixation, and frame fan connection structure of the system doors and windows are all designed according to safety levels. Compared with scattered assembled products, they have higher safety redundancy and are the preferred category for exterior windows in high-rise residential buildings.
While the industry is rapidly developing, it still faces many aspects that need to be regulated. Opaque labeling of product parameters, virtual labeling of performance indicators, and ambiguous quality assurance responsibilities are common problems. Many businesses only provide profile quality assurance and are not responsible for the comprehensive performance such as waterproofing and sound insulation of the entire window. With stricter supervision and improved testing systems, transparency of product information and clarification of quality assurance responsibilities will become a trend. In the long-term development direction, green solutions such as recycling, low VOC environmentally friendly materials, and photovoltaic integrated doors and windows will continue to be explored. System doors and windows will no longer be just building enclosure components, but gradually integrate multiple values such as energy conservation, safety, comfort, and intelligence.
