From the panoramic curtain walls of skyscrapers to the energy-saving doors and windows of ordinary residences, architectural glass is no longer a simple lighting material, but a core building material integrating multiple functions such as aesthetics, safety, energy conservation and intelligence. It has profoundly affected the design concept and use experience of modern buildings. With the transformation of the construction industry towards greenization and high-endization, the types of architectural glass are constantly enriched and their performance is continuously upgraded. From basic float glass sheets to deep-processed tempered glass, coated glass, insulating glass and laminated glass, to intelligent dimming glass, it comprehensively meets the personalized needs of different architectural scenarios and becomes an indispensable important part of modern buildings.
The core value of architectural glass lies in "functional adaptation", and different deep processing technologies endow it with differentiated performance advantages. Among them, safety performance is the basic requirement of architectural glass, and tempered glass and laminated glass are the mainstream safety glass categories. Tempered glass is processed by high-temperature quenching, its strength is increased by 4-5 times, and it breaks into granular shapes without sharp corners, which can effectively avoid personal injury. It is widely used in building doors and windows, balcony railings, shower rooms and other scenarios; laminated glass bonds multiple pieces of glass through PVB/EVA film. Even if it breaks, the fragments will be adhered by the film and will not splash. At the same time, it has excellent anti-impact, bulletproof and sound insulation performance. It is often used in banks, airports, high-rise building curtain walls and other scenarios with high safety requirements.
Energy-saving performance is the core competitiveness of modern architectural glass. Low-E coated glass and insulating glass have become the first choice for green buildings. Low-E (Low Emissivity) coated glass deposits a special metal film on the glass surface through vacuum magnetron sputtering technology, which can reflect far-infrared rays and reduce heat transfer between indoor and outdoor. It blocks external heat from entering in summer and retains indoor heat in winter, which can reduce building air conditioning and heating energy consumption by more than 30%, making it a core building material for energy-saving buildings; insulating glass is separated by spacer bars between two or more pieces of glass, and the interior is filled with dry air or inert gas (such as argon), which has the functions of heat insulation, sound insulation and anti-condensation. The Low-E insulating glass combined with Low-E glass further upgrades the energy-saving and sound-insulating performance to a new height, and is widely used in residential buildings, office buildings, hotels and other types of buildings.
Driven by aesthetic and personalized needs, the types of decorative architectural glass are constantly enriched. Ceramic frit glass prints inorganic glaze on the glass surface through screen printing, and forms a permanent pattern after high-temperature sintering, which can realize customized textures and colors. It is suitable for building facades, interior partitions, decorative background walls and other scenarios; embossed glass, with its unique surface patterns (such as Changhong, frosted, water ripple), has both decorative and privacy protection functions, and is often used in toilets, office partitions and other scenarios; ultra-white glass achieves ultra-high transparency with extremely low iron content (less than 0.015%), and can create a "crystal-like" transparent effect when matched with glass curtain walls, becoming a landmark material for high-end buildings. In addition, the application of new products such as intelligent dimming glass and building-integrated photovoltaic glass further promotes the upgrading of architectural glass towards intelligence and greenization.
In the future, architectural glass will continue to develop around the three directions of "green energy saving, safety and intelligence, and aesthetic personality". With the continuous improvement of national green building standards, the demand for energy-saving and low-carbon architectural glass will continue to grow; the R&D and application of functional glass such as intelligent dimming, self-cleaning and active energy saving will become more extensive; at the same time, customized production will become a trend, providing personalized glass solutions according to architectural design needs, helping to create more modern buildings with both aesthetic value and ecological benefits.
