Your windscreen is a critical component of your motor vehicle. It is classified as a “safety device”. The windscreen provides structural strength to the car and helps to keep passengers inside the vehicle in the event that an accident might occur.
The size of your car windscreen will obviously depend on the manufacturers design of your vehicle. As the windscreen size is dependent on the vehicles design specifications; there are almost as many car windscreens as there are models of cars. It is possible to remove and refit a windscreen from one vehicle to another in some circumstances, however there are risks such as unseen contamination from the second hand windscreen.
There are different sensors, attachments and mouldings that may be integrated or fabricated into the glass. These may include everything from rain sensors to hydrophobic coatings to multi-use antennas.
THE FITTING OF YOUR WINDSCREEN
Windscreens are fitted and bonded into the metal frame of your vehicle with technical precision. Special primers, sealants and adhesives containing polyurethane (also known as ‘urethane’) are usually used for this purpose.
Other Information about Windscreens
Most windscreens today tend to block virtually all damaging UV (ultraviolet) radiation.
DAMAGE TO WINDSCREENS AND YOUR M.O.T
In the event that your windscreen is damaged, there is a possibility that your car may fail its M.O.T. Windscreen inspections have been part of the annual M.O.T test since 1993.
What damage to my windscreen may cause my vehicle to fail the M.O.T?
Please refer to the diagram below, which may assist you when assessing damage to your windscreen.
- Damage larger than 10mm will fail in the drivers line of vision – Marked Zone “A”
- Damage larger than 40mm will fail in the rest of the swept area – Marked Zone “B”
- Significant scratching that impairs the drivers vision
Note: If a chip is in the drivers line of vision, it is important to know that the damage only needs to be bigger than 10mm for your windscreen to fail its M.O.T.
The M.O.T testers manual states that “any damage not contained within a circle of 10mm” therefore a cluster of minor damage to the windscreen is likely to fail the M.O.T
