• Antenna1

  2021–2026

  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.

• Blue1

  2021–2026

  Blue-tinted windscreens reduce glare and heat while maintaining a subtle, modern appearance.

  What it means

  A blue tint is a light coloration applied to the windscreen glass, usually during manufacture. It reduces solar heat transmission and glare from sunlight, particularly on bright days or when driving into the sun. The tint is integral to the glass itself — not a separate film — and is chosen by the vehicle manufacturer to balance comfort, visibility, and aesthetic consistency with the vehicle's side windows and rear window. Most vehicles come with a green or blue tint as standard; the choice depends on the manufacturer's design and regional climate considerations.

  How to tell

  Check your side windows by rolling one halfway down and holding a white piece of paper behind the glass. If you see a blue tint reflected in the glass, your windscreen will have the same tint. You can also ask your vehicle's dealership or service centre to confirm the windscreen tint specification. The tint is visible when comparing the windscreen to clear glass, though it may be subtle and harder to spot on overcast days.

  Replacement impact

  Blue-tinted replacement windscreens must match the original tint to maintain visual consistency with your side and rear windows. Most replacement glass is available in the correct tint through OE (original equipment) suppliers. There is no calibration requirement related to tint. The tint does not affect fitting time, cure time, or drive-away schedules. Ensure the replacement windscreen is specified with the blue tint to avoid a mismatched appearance.

• Brake Light1

  2021–2026

  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.

• Grey Privacy1

  2021–2026

  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.

• Heated Rear Windscreen1

  2021–2026

  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.
