Unknown Details of Automotive Glass Repair


Today there are increasing more car-lovers who care about every part of their cars, while there are still many people ignoring the automotive glass maintenance. It’s not rare that people make do with the cracked glasses to save troubles.

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

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

1. What kind of glass can be repaired?
There are mainly two types of automotive glasses, laminated glass and tempered glass.
Laminated glass: a interlayer of PVB film is sandwiched between two pieces of glasses which will stick glass together to avoid fragments splash around when broken.
Tempered glass: the glass will crumble into small granular chunks instantly when broken and are more likely to fall off. 

Based on the mentioned features above, most of windscreens are laminated glass which can be repaired after cracks. While other auto glasses except windscreen are mainly tempered glasses which crumble into small granular chunks instantly even fall off after breakage and thus can not be repaired. 

2. What kind of crack repair is recommended?
If the diameter of glass breakage is around 5mm, car owners should repair it asap in the professional maintenance store. The sooner, the better. But over 20mm, the repair effect will be poor and generally replacement will be recommended. 

3. Is it impossible to repair if not recommended? 
Many people would enquiry that wouldn't it be a waste to replace the glass if the damage is a bit large since a windscreen is usually sort of costly and most of them have not insured against auto glass breakage separately. Can they just make do with it?

In fact, the breakage, even though beyond the range of 20mm, can be repaired as long as it is not a big crack. 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/wind, etc.

Therefore, when there are cracks on the auto glass, car owners must get it repaired or replaced according to your own situation. It’s for your beloved car, but more for your safety!
