Evolution in laminated auto glass technology has brought options like heating elements to melt ice in cold weather, coatings to repel ultra violet light, integrated radio and telephone antennas and sensors controlling wipers. Laminated auto glass is thinner and lighter these to increase vehicle performance and passenger security. But with the evolution of windshields, prices of auto glass has increased considerably. As a result, motor vehicles owners prefer repairing their damaged windshield, rather than buying a new one. The cost of replacing a windshield may vary from $250 up to $1000; and repairs may vary depending on the severity of damage.
During the manufacturing process auto glass is tempered, that is, it is cooled in such a way to improve its strength. The glass used in autos is not the same composition as window panes used in buildings. Windshield glass is made by the fusion of several oxides which react together upon heating to form glass. These include silica, sodium oxide, potassium oxide, magnesium oxide, aluminum oxide and calcium oxide; all derived from sand, soda ash, and limestone. Auto glass is also laminated. A flexible plastic layer is placed between the inner and outer glass and keeps the two layers from shattering. The plastic interlayer is often tinted to act as an ultraviolet filter. When laminated glass is broken, the broken pieces of glass remain bound to the internal tear-resistant plastic layer, and the broken sheet remains transparent. Thus, visibility remains good.
Checking your windshield is important because a crack or chip that occurs in spring or summer can cause a break in the winter. Most people drive more in warm weather and more driving means more vibration, which can cause a ding to expand into a cracked windshield. Smooth driving is very important or else any shock may cause a small chip to suddenly become a large crack in the windshield.
Once you see a chip or crack in your windscreen the first thing is to thoroughly examine the spot. If the spot has a cone, a circle deep in the glass or spidering in the damaged area, the damage needs to be repaired. The spot will need immediate attention or it could develop into a long crack that will stretch across the entire windshield and require the replacement of the windshield itself. Placing a small piece of clear plastic tape over the impact point on the exterior of the windshield will keep dirt from getting into the cracks while awaiting repair.
As soon as you notice your windscreen has been damaged you should take immediate steps to prevent the chip or small crack from turning into a large crack across the windscreen. Steps you can take include putting a small piece of clear tape across the damage. This won’t stop the crack from spreading, but it will help to prevent dirt and moisture from entering into the laminated glass. Also try to avoid excessive vibration. So don’t slam the car door when entering or leaving the vehicle. Finally don’t use the car heater or defroster directly on the windscreen, since high heat can force the glass to expand and open up the cracks even further and allow the aforementioned dirt and moisture inside the lamination. Also try to park your car in the shade to prevent the sun from heating up the windscreen.
If you look after your windscreen and inspect it regularly, then with the exception for unforeseen accidents, there is no reason why your windscreen shouldn’t last the life time of the car.
