Windshield repair can occasionallybecome complicated if you do not know much about it. The windshield of ourvehicle is made up of three separate layers. A plastic sheet known as PVB orpolyvinyl butyrate is sandwiched between two layers of glass thereby holdingthe two layers together. The glass can get broken, which primarily depends onthe thickness of the outer layer as well as the force at which a rock hits theglass. Most of the damages to windshields are caused by chips of stones, andbefore you know it, the piece of rock spreads and creates a crack on thewindscreen. Stress, because of changes in temperature, as well as theconditions of the road, speeds up the entire process.
Gone are the days when windshields wererepaired using ultrasound-producing cleaning system to make the break dirt-freewhile at the same time filling the crack with an epoxy resin. Windshield repairhas undergone dramatic changes over the years thanks to improvement in science;nowadays, repairing of the windshield is preferred to the replacement ofwindshield.
But despite the advent of scientifictechnology in the windshield making industry, the aim is still the same: tosubstitute the air inside the break completely with a resin that will enhanceoptical clearness, reestablish the physical integrity of the windshield inaddition to preventing more damage.
Windshield repair is in fact, apreemptive maintenance. A lot of motorists whose windshields undergo damagecaused by rocks do not give much attention to this fact. Windshield repair isno longer a workable option once the chip of rock spreads out and develops to acrack.
The windshield plays a substantial roleas part of a vehicle’s restraint system; it works in collaboration with seatbelts and air bags. The windshield prevents possible ejection of an occupant incase of a road accident in which the vehicle somersaults or hits a boulder.
Four factors determine whether awindshield can be repaired successfully or not. They are namely, the depth, thesize, the type as well as the location of the damage.
If the crack on a windshield is up toabout 24 inches (or 61 centimeters), it can be successfully repaired. In spiteof this, it all depends on local and state laws.
The types of cracks also dictate howwindshields can be repaired without compromising its mechanical integrity.Cracks that are linear, pits or shaped like a star can be repaired withoutremoving the glass.
The location of the damage matters alot; if the cracks are located in the line of sight of the driver or at theedge of the windshield, it usually can’t be repaired.
