Do You Have a Chip in Your Windscreen?
The windscreen of a vehicle is one of the parts of the machine that is vital to our safety when driving. We need it to see where we’re going and is the protection that keeps us dry and warm. It’s for these simple reasons that ensuring the windscreen remains intact is vital.
Stones Can Cause Dents & Chips
Whilst windscreens are obviously made from toughened glass, given the role it plays, there are times when damage will occur. Stones thrown up from vehicles in front or from the other carriageway can cause dents and chips in the windscreen. Whilst these small pieces of damage may not be immediately hazardous, if left alone, they can spread and cause an integrity failure of the glass.
In recent years, the ability to repair windscreen chips has grown and has become a simple and cost-effective way of keeping the glass, rather than replacing it outright. It looks like witchcraft, but it’s not. So how does it work?
Glare From Lights & Weather
In most cases, when a windscreen is damaged, the impact point will be clearly visible. Even if it’s only small, it might not look serious but can have far-reaching implications if not addressed. A crack in the windscreen can make glare from lights and weather much worse, impacting on your ability to drive safely.
If you have a small chip or a crack in the windscreen, then you need to get it repaired as soon as possible. The first solution is to have some acrylic adhesive or an epoxy resin injected into the hole. The resin or adhesive has the same optical properties as the glass itself. That said, the temperature of the window needs to be right to enable the chemicals to do their work.
Before any resin is injected, the damage is opened slightly to allow a primer to be added. This ensures that the fluid can get into even the smallest of micro-cracks.
The next step is to remove any dirt or moisture from the area in question. This is usually done with a small vacuum pump. Once that’s completed, the resin can be injected into the chip, ensuring it fills all the available space. A hardening agent is then applied before it is solidified with an ultra-violet (UV) light. After a few minutes, the resin means the windscreen has the same structural integrity it had before it was damaged, and the repair will be almost imperceptible.
The Windscreen is the Most Important Part of an MOT
When it comes to your MOT, windscreens are very much part of the test. In terms of roadworthiness, windscreens are split into 4 zones; A, B, C, and D. The most important is zone A, which is centred on the steering wheel and is 290mm wide. If the damage is in this area, then it can only be repaired if the damage is 10mm in diameter or less. Other zones can have the damage repaired where the area is up to 40mm.
If you have a crack or chip in your windscreen, please don’t delay in getting it fixed. As tempted as you might be to grab some superglue and attempt it yourself, please don’t. You will need a professionally trained technician to be able to carry out the work. Get it fixed as soon as you can. It can also usually be done without it affecting your no-claims bonus on most insurance policies. It’s clear to see why chip repair is the way to go.
