There are usually layers of a glass windshield to provide the protection and the visual aesthetic that we are enjoying right now. To prevent the glass from breaking into smaller parts and fatally injuring the driver, a celluloid was inserted between two layers of glasses. It allowed the glass to break into smaller pieces that can’t hurt its passengers anymore. Additional improvements like the curvature and solar reflection followed after this. The modern windshield of today is already an amalgamation of other layers that gives the passengers protection as well as comfort in driving at high speeds.
One of the first layers is the tint of the glass. It is usually made of a plastic with varying shades of color according to what the user desires. It is the last one to be applied and can be suited to the wishes of the car’s owner. The second layer is usually a layer of tint that came from the manufacturer directly. It is mostly for protection against the sun’s UV rays. The succeeding layer is the glass and then the cellulite which holds the next glass layer as well. There are unique proprietary techniques for each glass manufacturer but all of the parts mentioned here are close to what they are manufacturing. The added uniqueness of the end glass product is usually dependent on the request of their customers or the car manufacturer.
The attachment of the glass can be done in a variety of ways as well. The glass can either be attached in frames or by the use of adhesives. There can also be a combination of such attachments. There are metal holders that might be holding it depending on the car manufacturer and model. All of these can best be removed by a glass repair professional in case you have a scratch on your windshield. The only consideration regarding the type of attachment to the glass usage is the safety and the mechanical advantage the attachment provides.
