How Windshield Repairs Work.

Posted by Joshua on Thursday Nov 22, 2012 Under Auto Glass, Auto Glass Repair

Auto glass repair works because of the unique construction of windshields. Modern windshields are composed of two sheets of tempered glass that have been laminated together. They are held together by a rubber inner layer that helps distribute the pressure when an impact damages the exposed outer layer of the windshield.

When an impact only pierces the first layer of the glass a repair is possible. If damage penetrates through both layers the rubber inner layer of laminate rubber keeps the glass from shattering inward at the driver. There are a few methods to do an auto glass repair, but the principles are very similar in both the old and new versions of the technology.

A resin and vacuum approach is the standard way to fill minor windshield damages. Cracks, chips and other damage can be repaired using a clear resin to fill the damage to the upper layer of the windshield. The area must be thoroughly cleaned, and all debris removed. Afterwards, the resin injected directly into the damaged area. The type of resin needed can vary greatly, depending on the type of damage that needs to be repaired. Calling an expert for auto glass repairs is generally the best idea. This is especially true if the driver has doubts or confusion about the process.

Once the resin is in place, a vacuum tool is used to remove all air pockets from the resin and the windshield. This process removes visual defects and strengthens the bond to the windshield. While numerous home repair kits are available, auto glass specialists are generally recommended. Auto glass services can preform most glass repairs quickly, cheaply and permanently.
