If thousands of families in the world use energy-saving doors and Windows, then the whole earth can be healthier, it is conceivable that doors and Windows in environmental protection and energy saving is really a great effort. So the heat loss of doors and Windows is actually related to the energy saving of doors and Windows. Today, Xiaobian will explain in detail what is the main reason for the heat loss of doors and Windows, hoping to help you!

Heat transfer coefficient levels for doors and Windows

The heat transfer coefficient of doors and Windows actually refers to the heat transfer of goods within the specified time. If the heat transfer coefficient is greater, the heat loss through doors and Windows will be large in winter, we know this principle after we know their home heat transfer coefficient level of doors and Windows, of course, the heat transfer coefficient of doors and Windows and related to the type of doors and Windows material, generally speaking, the worse the performance of doors and Windows at home air conditioning will cost more electricity, it is so simple.

Window wall ratio and window orientation

Window-wall ratio actually refers to the ratio of exterior window area to exterior wall area. Usually the heat transfer of doors and Windows is much less than that of walls. Secondly, it is required to determine the appropriate window wall ratio under the condition of satisfying the lighting and ventilation, so this is the need to carefully measure. At the same time, different orientation of solar radiation intensity, different doors and Windows will have different heat loss.

Air tightness of doors and Windows

Air tightness of doors and Windows is the ability to prevent air penetration when closed. The better the air tightness, the less natural heat loss, the more helpful it is to save energy for doors and Windows. Good air tightness of doors and Windows is of great benefit to doors and Windows.
