There are many decoration materials when decorating the house, and the window is the most important part of the house. There are many types of doors and windows. When we face many kinds of types, we don't know how to choose the doors and windows of our own home. Aluminum doors and windows coextrusion family say? We know about it then? Today small will take you a look at the characteristics of co-extruded aluminum doors and windows and aluminum doors and windows coextrusion installation considerations it! Hope you can help To you who are buying doors and windows.
Aluminum-plastic coextrusion doors and windows features
Plastic steel doors and windows are multi-cavity structure, with good thermal insulation performance, its thermal conductivity is very small, only l/357 steel, aluminum 1/250, visible plastic doors and windows insulation, insulation effect is significant, especially for heating and air conditioning The modern building of the equipment is more suitable.
According to the Institute of Physics of the Institute, the heat transfer coefficient of single glass steel and aluminum window is 64W/M2K; the heat transfer coefficient of single glass plastic steel window is about 47W/M2K; the heat transfer coefficient of ordinary double glazing steel and aluminum window It is about 3. 7W/M2K; and the heat transfer coefficient of double glass plastic steel window is about 2. 5W/M2K. Doors and windows account for 30% of the building's outer protective structure, and its heat dissipation accounts for 49%. It can be seen that plastic steel windows have good energy-saving benefits.
Aluminum-plastic coextrusion doors and windows
A: Look at the price Under normal circumstances, high-quality aluminum-plastic doors and windows due to high production costs, the price is about 30% higher than inferior aluminum-plastic doors and windows. Some aluminum-plastic doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have a tensile strength and yield strength that are much lower than the national standards and are not safe to use.
Second: look at the processing of high-quality aluminum-plastic doors and windows, fine processing, installation, stress, good sealing performance, switch freely. Inferior aluminum-plastic doors and windows, blindly use aluminum profiles and specifications, processing rough and shoddy, cutting instead of milling, not installed according to requirements, poor sealing performance, switch is not free, not only leaking wind and rain and glass burst phenomenon, but also encountered When it comes to strong winds and external forces, it is easy to scrape or knock down the push-pull parts or the glass, causing damage to people.
Third: look at the aluminum profiles used for high-quality aluminum-plastic doors and windows, thickness, strength and oxide film, etc., should comply with the relevant national standards, the wall thickness should be above 1.2 mm, and the tensile strength reaches 157 Newtons per square meter. The yield strength should be 108 Newtons per square millimeter and the oxide film thickness should be 10 microns .
Aluminum plastic coextrusion doors and windows use precautions
1. After the installation of aluminum-plastic doors and windows is completed, the surface protective film of the profile should be torn off in time and wiped clean; otherwise, the protective film backing will remain on the profile and it is difficult to clean.
2. The flat aluminum window sash should be closed in time on a windy day.
3, the flat aluminum window sash can not hang heavy objects on the hand.
4, swinging the upper hanging window is to change the direction of the switch handle to achieve different opening, to understand how to operate, so as not to cause damage.
5, push-pull aluminum plastic window when used, should always clean the push-pull track to keep it clean, so that there are no hard particles in the track surface and the groove.
6. Plastic steel aluminum-plastic doors and windows are provided with drainage system in the window frame and window sash to ensure the airtight performance and watertight performance of aluminum-plastic doors and windows. Users should not block the drainage holes of aluminum-plastic doors and windows during use. Causes the drainage performance of doors and windows to decrease.
Doors and windows are very important to our daily life, and we don't care which part of the environment is indispensable, so we need to know too much when choosing. The above is the introduction of Xiaobian today, and it is over here. If you want to know more information, please continue to pay attention to the decoration home.
