Mainly check the specifications, varieties, thickness, appearance quality and edge treatment of the glass, and detect the surface stress of the glass on site to determine the toughening state of the glass.
Another benefit of insulated window units is their ability to reduce condensation on the windows. Condensation occurs when warm air inside the house comes into contact with the cold surface of the window, causing moisture to form. This can lead to mold and mildew growth, as well as damage to the window frames. Insulated window units help to maintain a more consistent indoor temperature, reducing the likelihood of condensation forming on the windows.
