　　After the glass is placed on the wall, under direct sunlight, the glass absorbs the infrared light and part of the visible light. These lights are converted into heat energy in the glass body, which causes the temperature of the glass body to rise and thermal expansion around the glass.

　　If the glass is embedded in the aluminum alloy frame, the glass-inserted part cannot be exposed to the same exposure as the outside of the frame, so the exposed whole is unevenly heated, and the internal thermal stress is formed. The thermal expansion of the middle of the glass produces tensile stress on the glass edge The tensile stress is greater than the tensile strength of the glass, which will cause the glass to break.
