When it comes to performing mobile auto glass repair on a vehicle with a rear window defroster, there are some special considerations that need to be taken into account. The cost of repairing and caring for the vehicle after the repair is one of the main considerations. The ROLAGS guide (Automotive Laminated Glass Repair Standard), prepared by the National Windshield Repair Association (NWRA), specifies windshield size limits depending on the type of damage (white, hole, crack, etc.). If the damage occurs in the outer and inner layers of the glass, it is too deep to repair the windshield.
One advantage of windshield repair compared to replacement is that advanced driver assistance systems (ADAS), including sensors such as lane change warning sensors, don't usually need to be recalibrated after the repair is complete. In general, repair services for windshield chips under a quarter of a dollar and cracks up to three inches long can be easily repaired. It is not advisable to repair it if the windshield crack does not reach the driver's viewing angle, since the repair would cause some distortion that would impair the driver's vision of the road. Another place where the windshield should not be repaired is within the driver's line of sight (the glass covered by the driver's windshield wipers).Most side and rear windows require a complete replacement of the car's windows because they are made of tempered glass that cannot be repaired. In a head-on collision, the windshield guarantees up to 45% of the structural integrity of the vehicle's cabin and, in the event of a rollover, up to 60%, according to the Automotive Glass Safety Council.
Windshield repair technology is a sector that is advancing by leaps and bounds, so the ability to repair cracks or large cracks changes frequently and may vary depending on the repair company. Your best bet will be to take it to a reputable auto glass shop that performs repairs and replacements. Some auto glass repair providers will offer discounts if several chips or cracks are repaired at the same time. A windshield is considered a glass sandwich: an outer layer of glass, an intermediate layer of plastic, and an inner layer of glass.
