Rocks are enemies to the windshield of your car. When rocks hit windshields, they cause damages. Stone chips are extremely common especially at points with many large trucks on the roads or at places where road works are on going. Some stone chips are just a nuisance while others affect the vision of a driver. Others increase to be irreparable cracks when the damaged area is affected by elements over time.
At this point, many people are not decided whether they should go for auto glass replacement or repair would be enough. This is dependent on the role of the windshield and the safety aspects. The crucial thing is that you should be able to clearly see through the windshield. This is emphasized by the fact that many states have laws stating the point at which a windshield should be repaired or replaced.
There is a specific section of the windshield that is regarded as a “critical vision area.” This is section of windshield located about 300mm-400mm directly in front of drivers seating position extending full height of the glass. In many cases, a crack or stone chip outside this area can easily be repaired if the damage does not extend beyond 50 mm in diameter.
Windshield repair should not be done if the damage is located within critical vision area. The windshield is one of structural core components of a vehicle and integrated into airbag deployment. The front airbags for instance are designed to bounce off the windshield therefore it would pose a serious safety risk if the glass is poorly fitted when the inflation occurs during an accident.
A poorly fitting windshield will cause deployment of the airbag to easily push it out and causing a loss of strength in roof structure. This in turn will increase the probability of the occupants getting thrown from the vehicle.
Many people are at a crossroad when they have to choose between windshield repair and replacement. At times, there is not choice to replacement because of the safety aspects involved. When the affected area breaches one or several safety guidelines like loss of critical vision or structural integrity, the windshield should be replaced.
Windscreen replacement should not be taken lightly as it should adhere to motor safety standards. The technician carrying out the replacement should be a professional with a license to do the work. The glass and adhesive urethane used should also comply with the industry standards. Do not drive the vehicle until the time recommended for the adhesive to hold the glass properly has passed. This is why it is important to take your vehicle to an auto glass company with a reputation for safe windshield installation procedure.
In most instances auto glass repair costs far less that full replacement. However, you should be aware that it may fail to contain the damaged area. A good auto glass shop will subtract the cost of repair from that of full replacement.
