Energy-saving effect of aluminum-clad wooden doors and windows

With the improvement of people’s living standards, more and more people are beginning to pay attention to energy conservation and environmental protection. With the spread of this concept, people have begun to advocate energy conservation and environmental protection in all aspects. The price of aluminum-clad wood door and window manufacturers' profiles is not only in terms of food. Promote green and environmental protection, and start to promote energy conservation and environmental protection in all aspects such as articles. Today we will take a look at the energy-saving effect of aluminum-clad wooden doors and windows.

Steel windows and old aluminum alloy doors and windows in old buildings are easily deformed under wind and sun due to poor heat preservation and sealing performance. It has been found that the energy lost through the exterior windows of the house is very serious, and it is the main reason that affects the thermal environment of the building and causes excessive energy consumption. In traditional buildings, the heat transfer through windows accounts for more than 20% of the total energy consumption of the building; in energy-saving buildings, the heat loss of the windows accounts for a larger proportion of the total energy consumption of the building when the thermal resistance of the wall is increased by using insulation materials. The reason for the energy loss of doors and windows is the heat exchange between doors and windows and the surrounding environment. The process includes: solar radiation heat entering the building through glass; heat loss through glass; heat loss through window panes and window frames; heat at window openings The heat loss caused by the bridge; the heat loss caused by the penetration of cold air in the gap, etc.

The energy-saving effect of aluminum-clad wooden doors and windows appears here. Aluminum-clad wood doors and windows not only have high profile strength (close to aluminum alloy), but also have good mechanical properties and good heat insulation. Due to the addition of heat-insulating strips, the profile forms a variety of cross-sectional forms and has good strength. In addition, the glass fibers in the heat insulation strips are arranged in an orderly manner, which can withstand high tensile stress and high shear stress for a long time. The linear expansion coefficient of the heat insulation strip is close to aluminum, which has very good processing performance; at the same time, the inner and outer profiles can be made of different The profile composition of color and surface treatment method enhances the decorative effect; and can resist the corrosion of many acid and alkali chemicals.
