Understanding Windscreen Repair
Windscreen repair involves cleaning, drying, and filling the damaged area with a clear resin that closely matches the optical properties of glass. While the repair won’t make the damage invisible, it will significantly reduce its appearance and create a smooth, structurally sound surface. This reduces further screen damage and wear on wiper blades. Leaving chips unattended can lead to secondary cracks due to heat, moisture, frost, and vibrations, making future repairs more challenging.
Windscreen Repair Zones
Under the new standards, windscreen repair zones are defined as Zone A and Zone B. Zone A is a 400mm-wide area directly in front of the driver (500mm for HGVs and coaches), centered on the steering wheel and extending to the top arc of the driver’s wiper blade. No repairs are allowed in areas supporting ADAS technology. For any damage in the camera area, replacement and subsequent ADAS calibration will be required. In Zone A, chips within a 20mm diameter are repairable, while in Zone B, chips up to 40mm in diameter are eligible for repair.
The Importance of Prompt Chip Repairs
A small chip may seem harmless, but it’s more than just a blemish on your windscreen. Chips can quickly expand into larger cracks due to everyday factors like temperature fluctuations, road vibrations, or the impact of driving. Addressing chips early not only helps you avoid the cost of a full replacement but also ensures your windscreen retains its original strength and performance, crucial for both driver and passenger safety.
BSI Standards for Windscreen Repair
The latest BSI standards took effect on March 31, 2022, replacing BS AU 242a:1998, which was fully withdrawn in March 2023 after a year-long transition.
