[China Glass Net] Aluminum alloy doors and windows are a kind of doors and windows with more choices of doors and windows in the family. Although many families like to use aluminum alloy doors and windows, many people do not know how to choose materials to install, so today Xiaobian will tell you Said aluminum alloy doors and windows installation materials! 1. Reasonable design of window sash ratio and orientation Generally speaking, the heat transfer coefficient of the window is larger than the heat transfer coefficient of the outer wall of the same orientation and the same area. Therefore, the heat consumption of the heating increases with the proportion of the window wall. Under the conditions of lighting and ventilation, it is more effective to control the proportion of window walls than to set insulation curtains and window panels. That is, the smaller the window wall area is than the design, the smaller the heat loss and the better the energy saving effect. The heat loss is also related to the orientation of the outer window. The solar radiation intensity and the sunshine rate are high in the south and north directions, and the solar radiation heat obtained by the window is much. 2. Use energy-saving materials Due to the development of new materials, the main materials (frame materials, glass, seals, hardware accessories and sunshade facilities) that make up the window have made rapid progress. The use of energy-saving materials is an effective way to save energy in aluminum-clad doors and windows. Frame material: Window profiles account for about 15% to 30% of the outer window opening area, which is another weak link in energy loss in the outer window of the building. Therefore, the selection of window profiles is also crucial. At present, there are many types of energy-saving windows, such as: heat-dissipating aluminum, heat-dissipating steel, plastic profiles, aluminum alloy doors and windows, and the like. Among them, the heat-dissipating aluminum material has better energy-saving effect and is widely used, which not only retains the advantages of the aluminum profile, but also greatly reduces the heat transfer coefficient of the aluminum profile. The heat-dissipating aluminum material is divided into inner and outer parts by using a thermal bridge (cold bridge) technique in the section of the aluminum alloy profile. The heat-dissipating aluminum material is also called aluminum alloy door and window. 3, glass In the window, the glass area accounts for 65% to 75% of the window area. Ordinary glass has a small thermal resistance value and is almost completely absorbed by far-infrared heat radiation. Single-layer ordinary glass cannot achieve thermal insulation and energy saving effects. There are many types of aluminum alloy door and window glass. Different kinds of doors and windows, their light transmittance, shading coefficient, heat transfer coefficient are very different. Thermal conductivity and visor have a dual nature. For the winter, we want solar radiation to get heat and raise the indoor temperature. But in the summer, I hope to reduce solar radiation and avoid entering the room.
