Minor cracks can usually be repaired, but severe damage requires complete windshield replacement. You can visit car 4S shops, auto repair shops, or specialized glass stores for windshield replacement. There are two types of automotive glass: laminated glass and tempered glass. When laminated glass is damaged, the PVB film between the two glass layers prevents complete shattering. Even under severe impact, the glass won't fall apart completely, maintaining relative integrity without dangerous flying fragments. This makes laminated glass ideal for windshields. (After minor collisions, only small cracks appear, making repairs possible.) Tempered glass, when damaged, quickly fractures into countless small pieces, making the entire panel prone to shattering. This design facilitates passenger escape during emergencies, which is why it's commonly used for side windows and rear windshields. Windshield replacement details: As laminated glass, minor impacts may only damage the surface layer, allowing for crack repairs. However, severe impacts damaging the inner layer or causing extensive cracks/breaks require immediate replacement. The replacement process typically takes about four hours: removing the original glass (1-2 hours), cleaning old adhesive, applying new adhesive, installing the new glass, and letting it cure for approximately one hour until the adhesive hardens.
