TYPES OF WINDSCREEN CHIPS
The New Zealand Standard specifies the following types and sizes of damage for windscreen repair.
Windscreens can be repaired if the damage is no larger than:
Outside CVA Inside CVA Crack 100mm 25mm Star 30mm 15mm Horseshoe 25mm 10mm Bullseye 20mm 10mm Crater 5mm 2mm Combination As for each type of damage in the combination
CRITICAL VISION AREA (CVA)
The CVA is the shaded area below in the diagram. It's an area 150mm either side of the centre of the steering wheel (or driver's seat), 90mm from the top of the windscreen and 65mm from the bottom of the windscreen. WOF & COF inspections are more strict on windscreen repairs inside the CVA. If you're not sure whether a chip in the CVA can be repaired, call ASTROFIX now to arrange an inspection.
Why repair a windscreen chip?
- Enable the vehicle to pass the WoF/CoF inspection
- Prevent the damage from getting worse (cracking)
- Improve the optical appearence of the glass.
If the damage is not repaired it can crack causing the entire windscreen to need replacing. This cracking is usually caused by:
- Vibration - such as driving over a bump eg. bridge or pothole
- External atmospheric changes - direct sunlight, rain, frost or a combination of these
- Internal windscreen temperature change - blowing hot air on a cold screen, or cold air on a hot screen.
It's important to know that repairs are never completely invisible and there will be a residual 'dull spot' on the windscreen. However, repairs will generally significantly improve the visual appearance of the impact damage, as can be seen in the photo above.
For best results, repairs should be made as soon as possible after damage occurs, before the damage is contaminated by moisture and dirt. Avoid the use of glass cleaner and other treatments after the damage has occured and prior to the repair.
Placing a free 'patch sticker' over the windscreen chip immediately after the damage occurs will prevent dust & moisture contamination, which will improve the cosmetic quality of the repair.
Customers should ask Dan for a free saver patch sticker for future use.
