Damaged or cracked windscreens require prompt attention before driving much distance. However, there are varying opinions from providers and road safety associations about whether a damaged windscreen should be repaired or replaced immediately.
Most windscreens are made of two layers of laminated glass bonded together by a polyvinyl butyral (PVB) interlayer. Usually when a windscreen is damaged, it is only the outer layer of glass that is broken. If the damage is not severe, it may be possible to drive the vehicle to a repairer. Where safety is in question, it is always best to select the option that will reduce risks, but there may be some reasons for repairing a windscreen before electing to replace it. While even small chips may grow into cracks at any time, which could seriously affect driving safety, repairing a chip properly will result in the windscreen being as strong as before the damage. Where a crack has just appeared during a journey, it is important to try to stop the initial crack from growing. Windscreen crack repair services will save time and expense in this instance. Repairers should provide a lifetime warranty for their work, as well as a guarantee for roadworthy inspection.
Often times, a windscreen may be so damaged or chipped that repair is not possible or safe. In that instance, it is essential that the windscreen be replaced. A vehicle insurance policy may cover repair or replacement of vehicle windows and windscreen and policy holders should check with their insurer for an authorised provider. Many service providers are able to provide windscreen repair systems and manufacture or source items from Australia. All replacement windscreens should meet the requirements of Australian Design Rules, and comply with Australian Standards.
