The dual carbon policy drives the expansion of the building energy-saving film market, and the domestic market size will exceed 10.5 billion yuan by 2026

According to industry research data in May 2026, the domestic market size of building glass film has exceeded 10.5 billion yuan, with a growth rate of 9.2% for the whole year. With the support of national policies on energy-saving renovation of public buildings and renovation of old residential areas, energy-saving window films have been transformed from optional upgraded products to essential products. The global market size of window film has reached 2.72 billion US dollars, with the Asia Pacific region leading the world with a 42% share. Domestic office buildings, commercial complexes, and residential home decoration are the three core demand scenarios. The new version of the national standard "Energy saving Glass Film for Construction" has been officially implemented, which increases the mandatory requirements for total solar energy barrier rate, ultraviolet barrier rate, and VOC environmental indicators, and eliminates a large number of low-quality metal film and inferior PVC film products. Magnetron sputtering spectral selective film has become the mainstream in the market, with a total solar energy barrier rate of over 70% for high-end products, which can reduce building air conditioning energy consumption by 15% -22%. Special industrial subsidies have been introduced in the Yangtze River Delta and Chengdu Chongqing regions, providing equipment purchase subsidies to companies developing nano thermal insulation coatings and low radiation building films. Multiple film companies have simultaneously launched commercial building films that combine dimming, explosion-proof, and flame-retardant functions, and are simultaneously expanding their export business for energy-saving renovation projects in Southeast Asia.
