2025 Trends in the Door and Window Industry

I. The Upgrade of Energy Efficiency Standards: Industry Changes Driven by Policies

In recent years, governments around the world have successively introduced more stringent building energy conservation policies, aiming to reduce building energy consumption, cut carbon emissions, and achieve sustainable development goals. In China, the Ministry of Housing and Urban-Rural Development and other departments have been continuously revising and improving building energy efficiency standards, putting forward higher requirements for key indicators such as the thermal insulation and airtight performance of doors and windows. For example, the new standards clearly stipulate the limit values of the heat transfer coefficient of doors and windows in different climate zones. In cold regions, doors and windows with a low heat transfer coefficient are required to better maintain warmth, while in hot summer and warm winter regions, the emphasis is on the heat insulation performance of doors and windows to effectively block the entry of heat in summer.

At the same time, the grade standards for airtight performance have also been significantly improved. Good airtight performance can not only prevent air infiltration, reduce heat exchange between indoors and outdoors, but also reduce the intrusion of dust and noise, enhancing the comfort of the indoor environment. In addition, for indicators such as the shading coefficient and visible light transmittance of glass, the new regulations have also made detailed provisions, encouraging the use of high-performance energy-saving glass such as Low-E glass and insulating glass to further improve the energy-saving effect of doors and windows.

The introduction of these policies undoubtedly poses great challenges to the door and window industry. Products that do not meet the energy efficiency standards will gradually be phased out of the market. To stand out in the competition, enterprises must actively respond, increase investment in technology research and development, and promote the upgrading of products.

II. The Direction of Enterprise Technological Transformation

(1) Material Innovation: Enhancement of Core Competitiveness

• Application of New Profiles

• • Broken bridge aluminum profiles are widely popular in the market due to their excellent thermal insulation performance. However, with the improvement of energy efficiency standards, enterprises have begun to explore higher-quality profile materials. For example, some enterprises have adopted new types of thermal insulation strip materials, whose thermal insulation performance has been several times higher than that of traditional thermal insulation strips, effectively reducing the heat transfer coefficient of the profiles. At the same time, some enterprises have also developed high-performance aluminum alloy composite materials, which, while ensuring strength, further reduce the weight of the profiles and improve the overall performance of doors and windows.

• Upgrading of Energy-Saving Glass

• • As an important component of doors and windows, the performance of glass directly affects the energy-saving effect of doors and windows. In addition to common Low-E glass and insulating glass, enterprises have started to develop more advanced glass products. For example, triple-glazed insulating glass, by increasing the number of glass layers and the thickness of the air layer, further improves the thermal insulation and sound insulation performance of the glass. In addition, some enterprises have also introduced smart dimming glass, which can automatically adjust the light transmittance of the glass according to changes in indoor and outdoor light, not only meeting the lighting needs but also effectively controlling the entry of heat.

(2) Optimization of Production Processes: Improving Product Quality and Production Efficiency

• Application of Digital Production Technologies

• • With the advancement of Industry 4.0, more and more door and window enterprises have begun to introduce digital production technologies. Through automated production lines and intelligent equipment, enterprises can achieve precise control of the production process, improving the processing accuracy and consistency of products. For example, in the profile cutting process, the use of CNC cutting equipment can control the cutting error within a very small range, ensuring the assembly quality of doors and windows. At the same time, digital production can also improve production efficiency, reduce labor costs, and enhance the market competitiveness of enterprises.

• Promotion of Green Production Processes

• • In the context of the upgrade of energy efficiency standards, green production processes have become an inevitable choice for enterprises. Enterprises have started to adopt environmentally friendly surface treatment processes such as powder coating and fluorocarbon coating, reducing the emission of harmful substances during the traditional paint spraying process. In addition, during the production process, enterprises can optimize the process flow, improve the utilization rate of raw materials, and reduce the generation of waste, achieving efficient utilization of resources and friendly protection of the environment.

(3) Intelligent Development: Meeting the Personalized Needs of Users

• Research and Development of Intelligent Door and Window Systems

• • Intelligence is an important trend in the future development of the door and window industry. By integrating intelligent devices such as sensors and controllers, enterprises have developed intelligent door and window systems. Users can remotely control the opening and closing of doors and windows and adjust the ventilation volume through mobile APPs, voice control, etc., realizing an intelligent home experience. For example, intelligent doors and windows can automatically open or close according to the indoor air quality to keep the indoor air fresh; in case of windy and rainy weather, they can automatically close the doors and windows to avoid damage to indoor items.

• Upgrading of Personalized Customization Services

• • With the continuous improvement of consumers' pursuit of quality of life, personalized customization services have become one of the core competitiveness of door and window enterprises. With the help of intelligent technologies, enterprises have achieved full-process personalized customization from product design to production and manufacturing. Consumers can choose the style, color, material, and intelligent function configuration of doors and windows according to their own preferences and needs, and enterprises can quickly respond through intelligent production systems to provide consumers with customized products and services.
