New Energy-Saving Form Materials Become Climate

Energy-saving doors and windows are designed to meet high standards in key performance areas such as air tightness, water resistance, sound insulation, and thermal insulation. With growing pressure on energy conservation and emission reduction in China, improving the energy efficiency of building doors and windows has become a crucial strategy. These products not only help reduce energy consumption but also contribute to saving social resources and lowering costs for consumers.

As part of the evolution in materials, various new energy-saving technologies have emerged. Today, advanced products like aluminum alloy heat-insulating profiles, aluminum-wood composite profiles, steel-plastic integrated extruded profiles, and UPVC plastic profiles are widely used. Among these, UPVC (unplasticized polyvinyl chloride) profiles are particularly popular due to their use of polymer materials that offer excellent durability and thermal performance.

Vacuum glass is another innovative product in the field of energy-efficient building materials. It features a very thin gap layer—only 0.1 to 0.2 mm—separated by small particle supports. The cavity inside is evacuated to a vacuum level of at least 0.1 Pa, eliminating air and reducing heat transfer. Compared to regular glass, vacuum glass provides about four times better insulation. Its high thermal resistance also improves anti-condensation and frost resistance, making it especially beneficial for winter lighting in colder regions.

Smart glass is another breakthrough in the industry. Designed to address varying insulation needs across different climates and seasons, smart glass uses electrochromic technology to adjust its transparency automatically. After years of research and development, this intelligent glass has now entered mass production, marking a major step forward in making buildings more energy-efficient and comfortable for users.
