Windscreens have a special design that provides structural support for the vehicle and it is therefore important to have a strong and undamaged windscreen all time.
The structural design of windscreens involves two layers of glass which sandwich an inner layer of automotive safety glass. In the event of an accident, the inner layer holds together the broken outer layers. This gives explanation as to why windscreens crack when struck by objects rather than falling apart.
Most damage that occurs to windscreens is repairable but at times the entire windscreen needs replacement. Most chips and cracks can be repaired if you involve the services of skilled professionals.
It is important to call upon a skilled glass repair technician to evaluate a number of factors before deciding on whether or not your windscreen should be repaired or replaced. The following factors are considered when determining whether or not a windscreen should be replaced:
Type of Damage
There are various types of cracks. Some of them are easy to repair while some are rather hard. Multiple cracks are more challenging to repair and thus the best option can be to replace the entire windscreen.
Size and Depth
Size and depth are very important factors in making determination on whether a windscreen should be replaced or not.
Thanks to new technologies, it is becoming easier to repair wider chips and longer cracks. This should however be assessed by a professional as all cases are usually determined on an individual basis. Cracks up to 18 inches may be fixed but longer usually need full windscreen replacement.
After repair is done on a damaged windscreen, there might still be some mistiness, discoloration or unevenness. If the damage occurs in the driver’s line of sight, repairs would interfere with the clarity and even reduce visibility on the road for the driver.
Line of sight when driving varies according to the height of different drivers and therefore the technician evaluating the damage should put this into consideration. If the crack or chip is at the line of sight of the driver, it is a safer option to replace the whole windscreen.
Damages that generally cannot be repaired include:
- Edge cracks and chips
- Complex multiple cracks
- Very long cracks that are beyond 18 inches
- Contaminated cracks
- Damages that interfere with the line of sight of the driver
- Deep damages on both layers of glass
