[China Aluminum] Network is not the same as the number of days: because the strength of raw materials and elastic modulus and wear resistance are not the same, so that the use of high-performance aluminum alloy window life is usually greater than the number of plastic window life.
The function is not the same: both are near the energy-saving effect; but because of the difference in raw materials, the plastic window is easily deformed after a period of time, and the sealing function is not as good as the high-performance aluminum alloy window.
Different levels: Domestic aluminum alloy thermal break windows and plastic steel windows are respectively suitable for different construction cost groups. Statistics show that plastic steel windows are suitable for low-rise residences in general, and consumers of this level usually have The quality requirements of goods are not very high, and the high-function heat-insulating aluminum alloy window is suitable for all kinds of heights and all levels of construction, and the quality and life function are all able to withstand high standards.
