1. Energy saving. At present, building energy consumption accounts for 40% of the total energy consumption in China's society; And the energy consumption of doors and windows accounts for 45% to 50% of building energy consumption, making them the main cause of building energy loss. Therefore, we must improve the insulation effect of doors and windows in all aspects and guide everyone to use high-quality energy-saving doors and windows. In order to improve the thermal performance of doors and windows, the core task is to reduce the heat transfer from high temperature areas to low temperature areas, in order to minimize heat loss. And heat transfer is carried out through three ways: conduction, convection, and radiation, so all energy-saving measures for doors, windows, and curtain walls are centered around these three aspects. For sealing strips, reducing the thermal conductivity of the material can effectively slow down the speed of heat transfer; Reducing the compression permanent deformation of materials can achieve better sealing effect between various gaps of doors and windows, thereby isolating air convection from high temperature areas to low temperature areas and ensuring the energy-saving effect of the entire door and window. This type of EPDM sealing strip with low thermal conductivity and low compression permanent deformation will be a development direction for energy-saving rubber strips in the future.

2. Green, environmentally friendly, and biodegradable. With the continuous development of the home decoration market, various problems in home decoration have also emerged one after another. Especially indoor environmental pollution, due to its harm to human health, has attracted increasing attention. At present, some inferior glass sealing strips on the market, due to their poor quality, emit toxic and harmful gases that enter indoors for a long time, directly polluting the indoor environment and endangering human health; And it cannot be degraded and recycled after completing its service life, which also causes long-term damage to the environment. In recent years, the European Union has issued a series of regulations such as RoHS directive and REACH regulation to strengthen the protection of human health and environmental safety, and ensure sustainable development. Developing green, environmentally friendly and compliant door and window seals has become an imperative trend.

3. Professionalism, brand, and overall support. At present, there are numerous manufacturers of door and window sealing strips in China, and the quality and grade of their products vary greatly, resulting in a mixed market for sealing strips. Only enterprises that can utilize their resource advantages to integrate and form their own brands can grow and become stronger. Manufacturers of door and window sealing strips not only provide product support for door and window enterprises, but also need to intervene in the development and design process of doors and windows. Only in this way can the developed sealing strip products be more targeted and professional, promoting the application of new materials, new processes, and new technologies, and extending the sustainable development of the entire door and window curtain wall industry.
