• Heated Rear Windscreen8

  2010–2023

  Heated rear windscreen with integrated wires clears mist and ice when you switch on the demister.

  What it means

  A heated rear windscreen contains fine heating wires embedded within the glass. When you activate the rear demister, an electrical current passes through these wires, warming the glass and melting ice or condensation. This feature is particularly useful in cold or damp weather, improving rear visibility quickly. The heating grid is integral to the glass and connected to your vehicle's electrical circuit via connectors at the base of the windscreen.

  How to tell

  Look at the rear windscreen from inside the vehicle — you will see a fine grid of horizontal lines across the glass, typically bronze or copper in colour. On the dashboard or steering wheel stalk, there will be a dedicated rear-demist button, usually marked with a windscreen symbol and heating lines. If in doubt, ask your vehicle's service centre or consult your handbook.

  Replacement impact

  Replacement rear windscreens with heated grids are widely available as original-equipment aftermarket or dealership parts. The new glass must include the factory heating grid and electrical connectors intact. The technician will reconnect the heating circuit to your vehicle's rear-demist switch. Heated rear windscreens are bonded glass, so adhesive cure time applies; drive-away time will be confirmed by the fitter on the day.

• Antenna7

  2010–2023

  An aerial laminated into the windscreen or rear window restores radio, DAB or TV reception without a roof-mounted mast.

  What it means

  An antenna is a conductive print laminated into the glass during manufacture, typically used for radio, DAB (digital audio broadcasting) or television reception. It replaces the traditional roof-mounted aerial mast found on older vehicles. The antenna is integrated into the glass interlayer and connected to the vehicle's receiver unit via a connector embedded in the glass edge. This design offers a cleaner aesthetic, reduces wind noise, and eliminates the vulnerability of a protruding mast to damage or theft.

  How to tell

  Check your vehicle's roof — if there is no visible aerial mast, your car likely has a laminated antenna. You can also ask your dealer or service centre whether your windscreen or rear window carries an antenna print. The connector may be visible on the glass edge or inside the door frame trim.

  Replacement impact

  When replacing glass with a laminated antenna, the replacement must carry the matching antenna print and connector to restore reception immediately on fitting. Aftermarket or original-equipment glass with the correct antenna specification is essential; a plain replacement will leave you without radio or DAB signal. Our fitters verify the antenna specification during booking and source the correct variant before the appointment.

• Brake Light6

  2010–2023

  A brake light integrated into the rear window glass itself, requiring a matching replacement to reconnect the original lighting circuit.

  What it means

  A brake light integrated into the rear window glass is a lighting element built directly into the glass panel during manufacturing. Rather than using a separate lamp cluster mounted to the vehicle body, the light circuit is routed through conductive elements — typically a silkscreen pattern, wire network, or bracket assembly — embedded in or bonded to the glass itself. When you brake, this integrated light illuminates to warn following traffic. It combines functionality with design integration, reducing the number of separate components on the rear of the vehicle.

  How to tell

  Check your vehicle's rear window for a visible pattern of fine lines or wires running across the glass, usually near the top edge or spanning the upper portion. Look at your vehicle's manual or contact your dealer's service centre — they can confirm whether your rear window carries an integrated brake light. If you see a separate brake-light cluster mounted to the bodywork instead, your vehicle does not have this feature.

  Replacement impact

  The replacement rear window must carry the identical integrated brake-light pattern so the original lighting circuit reconnects without modification. The conductive elements — whether silkscreen, wiring, or bracket fittings — must align precisely with the vehicle's electrical connections. Using a standard rear window without this pattern would disable the brake light. We source the correct OE-specification glass to ensure a seamless fit and restore full functionality.

• Green6

  2010–2023

  Green tint reduces glare and improves visual comfort by filtering certain light wavelengths.

  What it means

  Green tint is a light-filtering coating applied to the glass during manufacture. It absorbs and reduces transmission of certain wavelengths of light, primarily to cut glare from sunlight and reflections. The tint is subtle — often barely visible to the naked eye — but measurably improves visual comfort during prolonged driving, particularly in bright conditions. It's a factory specification chosen by the vehicle manufacturer to balance daylight comfort with interior visibility and aesthetic consistency across all glass in the vehicle.

  How to tell

  The easiest way to check is to roll your side window halfway down and hold a piece of white paper behind it. Look carefully for a tint cast — green tint will appear as a subtle green hue compared to clear glass. Your windscreen will have the same tint as your side windows. You can also ask your vehicle's dealership or service centre — they'll have the original specification on file.

  Replacement impact

  Green-tinted replacement glass must match the original tint specification to maintain visual consistency across all windows and preserve the vehicle's interior aesthetics. Aftermarket OE-equivalent (OEE) green-tinted glass is widely available, though some vehicles may require original equipment (OEM) dealership glass if the tint specification is proprietary. Tint does not affect calibration, cure time, or installation procedure — it's a cosmetic and functional specification only.

• TV Antenna6

  2010–2023

  A TV-reception aerial printed into the rear window, typically for in-car entertainment systems.

  What it means

  A TV antenna is an aerial pattern laminated into the rear windscreen or rear side window to receive broadcast television signals. It's a separate system from the vehicle's radio or mobile antenna and is typically found in vehicles equipped with rear-seat entertainment systems. The antenna is printed directly onto or into the glass during manufacture, so when the glass is replaced, the antenna pattern must be reproduced on the replacement to maintain reception quality.

  How to tell

  Check your vehicle's specification sheet or handbook for rear-seat entertainment or TV tuner capability. If your car has a rear-seat entertainment system with a TV tuner, the rear window will have a TV antenna. You can also ask your dealer or service centre to confirm whether your vehicle has this feature.

  Replacement impact

  When the rear window is replaced, the replacement glass must include the matching TV antenna print to preserve reception. OEM (original equipment manufacturer) glass is typically required to ensure the antenna pattern is identical. The antenna is passive and requires no calibration or specialist procedures after fitting. Cure time for bonded rear glass is required; the fitter will confirm the drive-away time on the day.

• Mobile Telephone3

  2018–2023

  Built-in telephone aerial in the rear window for older luxury vehicles with handset systems.

  What it means

  A mobile telephone system fitted to certain older luxury vehicles consists of an aerial and connector circuit printed or bonded into the rear window glass, paired with a handset mounted inside the cabin (typically between the front seats). The aerial enables radio transmission and reception for the in-car telephone. When the rear window is replaced, the new glass must carry an identical aerial print so the handset's electrical connector mates correctly and the system functions.

  How to tell

  Check whether your vehicle has a handset unit mounted between the front seats or on the centre console. If present, your rear window will have a fine printed pattern or metallic trace visible on the glass itself (usually near the top edge). Ask your dealer or service centre to confirm whether your model is fitted with a factory mobile telephone system; they can verify this from the vehicle specification.

  Replacement impact

  The replacement rear window must be an exact OE match with the identical aerial circuit printed into the glass. Aftermarket glass typically does not carry this feature. You will need to source the glass from the vehicle manufacturer or a specialist supplier holding OE stock. Fitting is standard; the handset reconnects once the glass is installed. Cure time applies as with any bonded rear window.

• Grey Privacy2

  2010–2023

  Dark grey tint on rear windows provides privacy and reduces interior heat and glare.

  What it means

  Dark grey tint, formally known as privacy glass, is a factory-applied tint created through a deep-dipping process during glass manufacture. The pigment is infused into the inner surface of the glass, darkening the rear windows (and sometimes rear doors) significantly more than the front. This reduces heat transmission, minimises glare, and obscures the interior from outside view. It's standard on the rear half of many modern vehicles.

  How to tell

  Compare the rear side windows and rear window (backlight) to the front side windows — the rear glass will be noticeably darker. Check your vehicle documents or ask your dealership service centre if you're unsure whether your car left the factory with privacy glass.

  Replacement impact

  Dark grey tinted glass must be sourced from the Original Equipment Equivalent (OEE) or dealership to ensure colour and transmission match your vehicle's existing rear glass. The tint is integral to the glass itself, not a surface coating, so aftermarket non-tinted glass will look visibly mismatched. Replacement does not require any calibration and follows standard bonded-glass cure times for rear windows.

• Acoustic (Noise reduction)1

  2018–2023

  Acoustic glass reduces cabin noise for a quieter, more comfortable ride.

  What it means

  Acoustic windscreen glass is laminated with a special acoustic interlayer that absorbs and dampens sound vibrations. It reduces exterior noise—from traffic, wind, and road surface—before it enters the passenger compartment. This makes the cabin noticeably quieter and creates a more peaceful driving experience. It's a comfort feature, not a safety one; standard laminated windscreens already meet impact safety requirements.

  How to tell

  Check your windscreen for an ear symbol, the word 'Acoustic', a capital 'A', or the term 'SoundScreen' printed in one of the four corners. These markings indicate acoustic-grade glass. You can also ask your vehicle's dealership or service centre whether your model came fitted with acoustic glass—it's often a factory option on comfort or premium trims.

  Replacement impact

  Acoustic glass is always laminated and bonds to the frame like any standard windscreen, so replacement follows the normal bonded-glass procedure. No specialist calibration is required. The replacement technician will fit it using standard adhesive and sealant. Cure time and drive-away restrictions are identical to standard laminated windscreens. Acoustic glass is widely available as an aftermarket OE-equivalent option.

• Laminated1

  2018–2023

  Laminated windscreens hold together when they crack, staying bonded to an inner layer rather than shattering into dangerous shards.

  What it means

  Laminated glass consists of two glass panes bonded to a tough plastic interlayer, usually polyvinyl butyral (PVB). When struck, the glass cracks but the interlayer holds the pieces in place, preventing the sharp shards that would scatter from tempered glass. This design prioritises occupant safety — the windscreen remains structurally sound even after impact, reducing the risk of ejection and keeping wind and weather out of the cabin. Laminated glass also provides sound dampening and blocks most ultraviolet light. All modern windscreens are laminated as standard.

  How to tell

  Look at your windscreen edge-on — you'll see a thin darker line (the interlayer) sandwiched between the two glass panes. Tap the glass gently with your knuckle: laminated glass produces a duller, more solid sound compared to the sharper ring of tempered side or rear windows. Your service manual or dealer can confirm, but all production windscreens are laminated.

  Replacement impact

  Laminated glass is bonded to the frame with structural adhesive, so cure time applies after replacement. Your windscreen is safety-critical — it contributes up to 30% of vehicle structural integrity and supports airbag deployment. The adhesive bond must fully cure before the vehicle is driven normally; your fitter will confirm the specific drive-away time before releasing the car. This is true whether or not your windscreen has camera or sensor features.

• Solar Control1

  2018–2023

  Solar control glass absorbs infrared rays to reduce heat and improve cabin comfort.

  What it means

  Solar control is a coating applied to the windscreen that absorbs the sun's infrared radiation rather than allowing it to pass through into the cabin. This reduces solar heat gain, helping to keep the interior cooler and more comfortable, particularly in warm weather or direct sunlight. The coating is transparent to visible light, so it doesn't darken the windscreen or affect visibility. It's a passive thermal management feature that works continuously whenever the sun is shining on the glass.

  How to tell

  Check your vehicle's specification sheet or contact your dealership service centre to confirm whether solar control glass is fitted. Some manufacturers list it as 'solar control windscreen', 'heat-reflective glass', or 'thermal management glass'. It's a factory-fitted feature and won't be visibly obvious from outside the car — the coating is integral to the glass itself.

  Replacement impact

  Solar control glass is a factory-fitted specification. When replacing the windscreen, a solar control variant must be sourced to match the original. This is a standard glass type with no special fitting implications or calibration requirements. Cure and drive-away times follow normal windscreen bonding procedures. Confirm with your fitter that the replacement glass includes solar control to maintain the original thermal performance.
