Unknown Details of Automotive Glass Repair


Today there are increasing more car-lovers who care about every aspect of their car, however, there are still many car owners ignoring automotive glass maintenance. It’s not unusual for drivers make do with a cracked windscreen to save money.

In fact, although automotive glass does not require regular replacement like some wearing parts, periodical inspection and repair after damage are important. 

Let’s discuss the common problems of automotive glass repair. 

1. What kind of glass can be repaired?
There are two types of automotive glass, laminated glass and tempered glass.
Laminated glass has an interlayer of PVB film sandwiched between two pieces of glass which sandwiched together to avoid shattered glass being spewed around when broken.
Tempered glass: this glass will crumble into small granular chunks instantly when broken and are more likely to fall off (very much like when a glass is dropped on the floor).

Based on the mentioned features above, most windscreens are manufactured with the laminated procedure, which can be repaired if chipped. While most other auto glass are mainly tempered glass which shatters into small granular chunks instantly and even fall off after breakage and therefore can not be repaired. 

2. What kind of crack repair is recommended?
If the diameter of a glass chip is around 5mm, car owners should repair it as soon as possible by a professional technician. The sooner, the better to avoid it from developing into a large crack that will no longer be repairable. But if the chip is larger than 20mm, the repair effect will be poor and generally replacement will be recommended. 

3. Is it impossible to repair if not recommended? 
May car owners will continue to drive their vehicles with cracks, simply because they do not have glass coverage and windscreens are generally expensive. Can they just make do with it?

In fact, the breakage, some chips and cracks up to 20mm may be repaired as long as it is not a big crack. A professional technician can evaluate it and determine if it is possible. However, there are certain safety hazards when the windscreen suffers frequent stress from the increased wind resistance on the highway, or from car washing and rain, snow and wind, etc.

Windscreens are not just to keep the elements out, rather they perform a structural component of the roof in the event of a vehicle roll over.

Therefore, the windscreens have chips or cracks is recommended to get it repaired or replaced according to your own situation. It’s cosmetics for your beloved car, but more importantly for your safety!
