Wind Screen Replacement
Wind Screen Replacement Service
Every windscreen is different. DSA Autocentre takes account of all sorts of features and technology when replacing a windscreen.
What sort of things do we take account of when replacing a windscreen?
To see if your windscreen is tinted, hold a piece of white paper to the rear of the screen so that it is half covered by the glass and half exposed. Look for any obvious variation in colour.
Top Tinted Windscreens
This is a strip of darker tinting across the top 150mm or so of the windscreen. It's there to help reduce the glare from bright, especially low, sun.
Solar Reflective Windscreens
These are screens have a special coating between the PVB (plastic) interlayer and the outer pane of the windscreen. Most solar coated screens appear to have a slightly different hue to them (the mauve/pink of some Renault screens is a more obvious example). These screens help reflect UV light from the sun's rays which in turn increases the efficiency of the air conditioning system, reduces the degradation of interior trim and improved fuel efficiency.
Unlike the more obvious heating elements in a rear window those in a windscreen are very fine. Look for very fine wavy lines that run top to bottom across the width of the screen these are the heating elements. The elements are usually in two parts and there may be a gap at each side as well as a slightly larger gap down the centre of the screen.
Automatics Rain Sensors
This is a system that automatically detects rain as it hits the windscreen. Usually set via a switch on the steering column a rain sensor means that the speed of the wipers will adjust automatically from stop to full speed according to how hard rain is falling. The sensor is fitted behind or near to the internal rear view mirror. Rain landing on the screen causes a change in the angle of the light hitting the sensor which in turn activates a switch and triggers the wipers. The harder it rains the faster the wipers operate.
Automatic Light Sensors
A sensor detects changes in light levels automatically turning on a vehicle's headlights when light is low which in turn adds to driver safety. The light sensor system is fitted behind or near to the internal rear view mirror and is sometimes combined with a rain sensor. It will turn on the dipped headlights whenever conditions demand for example when driving through a tunnel. The vehicle headlights must be switched to 'auto' for the light sensor to work. Lights will turn off automatically once the vehicle is back in the light. Note - if your vehicle has day running lights these will not be controlled by the sensor.
A space in the paint band makes it possible to see the Vehicle Identification Number (VIN) from the outside. Usually located at the bottom of the passenger side of the windscreen.
Thin metallic line located in or on the surface of the windscreen. If your vehicle doesn't have an exterior antenna, there is probably one in or on the windscreen. However, a small number of vehicles have both.
Head Up Displays (HUDs)
Still a relatively rare option the Head-Up Display or HUD is an aircraft style system of projecting key driving information on to the lower section of the windscreen directly in the driver's field of vision. Speed, signal and other driver information is projected onto the windscreen.
To determine if a vehicle has a heated wiper park, look for brownish lines running back and forth along the bottom 150mm or so of the windscreen i.e. the area in which the vehicle wipers come to rest.
Modern windscreen glass has a black ceramic or enamel band (sometimes called the frit) around the periphery which is baked onto the internal surface of the glass. The band has an etched surface to enable special windscreen adhesives to bond to the glass as well as acting as UV light protection for the adhesive preventing it from deteriorating over time. This black band includes a border of dots. Some windscreens also use the dots as a third sun visor to block the sun behind the rear view mirror where most visors don't reach.
