Chip Repair and Windscreen Safety

Introduction

Have you been driving with a small chip on your windscreen, fearful that it may expand into a running crack along with the windscreen?

We decided to approach some of the experts for more information as to how and when such a chip can be repaired and when a windscreen would need to be replaced.

Is chip repair performed only on the windscreen or on all other windows as well?

Yes, Windscreen only. As long as the damage is limited to the outer layer of the glass.

 

What is the most important distinguishing factor between a chip and a small crack? 

“Chips” are can be placed into 3 different categories:

1. Bulls-eye: No visible legs (small cracks) - mostly round or half moon in shape not larger than 10 mm Ø in A zone;
2. Star: legs (small crack lines) are clearly visible but are not longer than 25mm in C zone;
3. Combination (star & bulls-eye)

“Small crack”: is when a Star chip or a combination chip have the single leg that is longer than 25mm but is not exceeding 40mm.

Could it be done on all vehicles or are there factors that might exclude it from being performed on specific vehicles or surfaces?

All vehicles that have a laminate front windscreen consisting of 2 glass layers and the damages are limited to the outer layer.

What if there are safety film installed on the windscreen?

Film on the inside -Yes; Film on the outside of the windscreen - No 

Can several chips be repaired on the same windscreen or the same surface?

Yes - more than 1 chip can be repaired - as long as it falls within the specification of each zone. 

What are the risks of having chip repair done next to the street instead of by professionals?

There may not be a warranty. 

Are there any signs to look for that a chip may become a “runner” and cause further damage?

No, not really. It depends on road conditions, temperature or a combination thereof.  

Are there specific spots on the windscreen where a chip is more dangerous to address or where it cannot be repaired?

Yes - see zones indicated above and below.

Is there any specific time frame for detection that a vehicle owner should repair a chip to ensure it does not escalate into something bigger?

Yes, as soon as possible.

What is involved in the process of repairing a chip?

A PG Glass Repair system first creates a vacuum above the damage site in the outer layer of the laminated glass, which extracts air, dirt & moisture from the hairline fractures. A specialised filling/bonding resin is pressed in and then released into the chip and hairline fractures and is drawn into the evacuated voids in the chip. The resin is then cured with a specialised UV light. 

How long does it take? +/- 15 min
How much does it cost? It is better to consult with your local dealer where the chip is repaired.

Chip Repairs and Windscreen Safety

As noted in our campaign repairing a chip on a windscreen saves you money and time. However, not all chips can be repaired:

The size of the chip

To be able to repair a chip on your windscreen, the size of the chip needs to be no bigger than 25 mm across.

The position of the chip

The impact point must be at least 3cm from the visible edge of the glass.

The Driver's line of vision

If the chip is in the driver's line of vision, the damage must not be more than 10 mm across. The driver's line of vision is an area approximately 30 cm wide and centres in the middle of the steering wheel.

NB: Width of steering wheel impacts width of zone A i.e. 290 mm / 29 cm or 300 mm / 30 cm

Your friendly PG Glass representative will inspect your chip to determine if it is repairable. In the event that a chip is not repairable a windscreen replacement can be arranged via an insurance claim or a cash sale.

Risk

In the case of a PG Glass Medic® Chip Repair, every precaution is taken to ensure that a chip being repaired does not "run" during the repair process. This, however, does occur infrequently(+/- 5% of the incidents). PG Glass cannot be held responsible in this case. This also applies to chip repairs being done on a Shatterprufe®, Safevue® & OE manufactured windscreens.

The PG Glass Quality Promise applies to this service:

• If you are dissatisfied with the workmanship of the PG Glass Medic® Repair System, we will deduct the cost of the windscreen repair from a new Shatterprufe® or Safevue® replacement windscreen.
• If the original repair was paid by your insurance company and they approve a windscreen replacement they will be credited for the repair invoice cost. You will be liable for the excess payment on the windscreen replacement depending on your insurance policy.
• If you are paying cash for the windscreen replacement the cost of the chip repair will be deducted from the price of the new windscreen (Shatterprufe® or Safevue®).
• Windscreen replacements carry a Lifetime Guarantee on Workmanship and a Lifetime Warranty on the product and are not transferable to the next owner.
• Tampering with the windscreen in any manner will render the guarantee null and void.
