What material is the window glass made of?

1, window glass is generally tempered glass.

2. Tempered glass? Belonging to safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, compressive stress is usually formed on the surface of glass by chemical or physical methods. When the glass bears external force, the surface stress is first offset, which improves the bearing capacity and enhances the wind pressure resistance, cold and heat resistance and impact resistance of the glass itself.

3. Tempered glass is made by cutting ordinary annealed glass into the required size, then heating it to about 700 degrees near the softening point, and then cooling it quickly and evenly.

Window glass introduction:

Glass is formed by melting silicon dioxide and other chemicals together. When melting, a continuous network structure is formed, and when cooling, the viscosity gradually increases and hardens, resulting in crystallization of silicate nonmetallic materials. Ordinary glass is mainly composed of silicate double salt and is an amorphous solid with irregular structure.

Household window film is a product directly installed on the inner surface of window glass, which is helpful to correct the temperature imbalance in strong light area or back sun area, dispel dazzling and uncomfortable glare, and make indoor personnel more comfortable.
