Our parts team performs a detailed specification check to confirm your glass matches your factory build — camera bracket, acoustic layer, HUD surface, heated zones and all.
You're matched with an approved specialist in your area. Because your GLS requires post-fit ADAS calibration, the fitting is scheduled at a workshop (not mobile) so calibration targets and diagnostic equipment are available.
On fitting day, your specialist removes the old windscreen, transfers the camera bracket trim, fits your new glass with the correct encapsulation gasket, and performs static calibration indoors — typically completed within a couple of hours.
Your fitter confirms the minimum drive-away time before you leave, and your two-year parts and workmanship warranty begins.
All work comes backed by a two-year warranty covering glass quality and fitting integrity.
Your GLS windscreen must be fitted at a workshop rather than mobile at your home, because all current variants require static camera calibration after replacement. This calibration uses precision target boards and diagnostic tools in a controlled indoor environment — it cannot be done on a driveway.
UKCG's no-split rule ensures your specialist fits the glass and completes calibration in a single visit, keeping you accountable for the safety-critical ADAS realignment. Mobile fitting is not available for this model.

Acoustic glass reduces cabin noise for a quieter, more comfortable ride.
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.
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.
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.
The moulded trim that surrounds your camera and sensor cluster at the top of the windscreen, typically transferred or supplied with replacement glass.
A bracket for safety features is the moulded plastic or composite shroud that sits at the top of the windscreen, framing and protecting the camera and sensor cluster mounted behind the rear-view mirror. This trim cover houses forward-facing driver-assistance cameras and sensors — equipment that monitors the road ahead for lane-keeping, collision warning, adaptive cruise control, and similar safety functions. The bracket itself is part of the vehicle's structural frame, but the trim cover you see is what protects and aesthetically integrates the technology into the windscreen area.
Look at the top centre of your windscreen, just above or around the rear-view mirror. If you see a dark moulded shroud or trim panel — often rectangular or tapered — with a visible lens or sensor window, your vehicle has a bracket for safety features. Your service history or handbook will list any ADAS (Advanced Driver Assistance System) technologies fitted. Ask your dealer or service centre if your vehicle has forward-facing cameras or sensors; if it does, you have a bracket for safety features.
On windscreen replacement, the trim cover is typically transferred from your old glass to the new one, or supplied pre-integrated with the replacement depending on the variant. This means minimal disruption to your safety system during the swap. However, if the bracket requires recalibration after glass replacement — which depends on your specific vehicle and camera type — the job may require static calibration (using a target board) or dynamic calibration (a road drive). We confirm the exact calibration procedure when we look up your vehicle.
A camera mounted near the rear-view mirror monitors the road ahead for lane-keep and traffic-sign features.
A forward-facing camera positioned in the windscreen header area (typically mounted on or near the rear-view mirror bracket) captures video of the road ahead. This camera feeds data to driver-assistance systems such as lane-departure warning, lane-keep assist, autonomous emergency braking, and traffic-sign recognition. The camera is a core component of modern ADAS (Advanced Driver Assistance Systems) and requires precise alignment after windscreen replacement to ensure these safety features function correctly.
Look for a small dark triangular or lens-shaped component mounted in the black plastic trim area above the windscreen, typically centred near the rear-view mirror or slightly to one side. Your vehicle's handbook or infotainment menu may reference 'Lane Assist', 'Traffic Sign Recognition', or 'Autonomous Emergency Braking'. Ask your dealer or service centre directly if your car is equipped with a forward-facing camera system.
Windscreen replacement on camera-equipped vehicles requires calibration of the camera system after the new glass is fitted. The exact calibration procedure—whether static (using a target board in a controlled environment) or dynamic (road-based)—varies by vehicle make, model, and year. We confirm the precise calibration requirement when we look up your specific vehicle. Calibration ensures lane-keep, sign recognition, and emergency-braking systems function safely. This may extend the fitting schedule and may necessitate workshop-based fitting rather than mobile attendance.
Factory-bonded rubber or polymer trim means your replacement glass arrives ready to fit as one complete unit.
Encapsulation is a rubber or polymer gasket moulded directly onto the glass edges during manufacturing. The trim is bonded to the glass at the factory — either by injection moulding, PU robot extrusion, or adhesive bonding. When you need a replacement, the entire panel arrives with its trim already attached, so the glass and gasket are replaced together as a single unit rather than as separate components.
Check your current windscreen or rear window edges. If you see a continuous rubber or polymer seal running around the perimeter that appears moulded or permanently bonded to the glass itself — rather than a separate trim clipped or screwed to the frame — your glass is encapsulated. Ask your dealer or service centre to confirm; they can also check your vehicle specification sheet.
Encapsulated glass simplifies replacement because there's no separate trim to remove, refit, or source. The bonded gasket is replaced as part of the glass unit, which reduces installation complexity and potential leak points. Cure time and drive-away procedures remain unchanged. No additional sourcing delays — encapsulated replacements are stocked as complete assemblies by most suppliers.
Green tint reduces glare and improves visual comfort by filtering certain light wavelengths.
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.
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.
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.
Heated windscreens use embedded wires to quickly clear ice and condensation in cold weather.
A heated windscreen is integrated with a fine mesh of electrical wires embedded within the glass itself. When activated, these wires generate heat to warm the windscreen surface, helping to rapidly clear frost, ice, and condensation during cold or damp conditions. This feature improves visibility and safety in winter driving and reduces reliance on engine heat and demister air, which can be slower on very cold mornings.
Check your vehicle's handbook or contact your dealership service centre — they can confirm whether your model includes this feature. Look for a dashboard symbol (usually a windscreen icon with heat waves) when you activate the function, or check your infotainment settings for a heating or climate option linked to the windscreen. Some vehicles have a dedicated button on the stalk or console.
Heated windscreens require replacement glass to be of the correct heated specification — standard unheated glass cannot be fitted. The replacement glass must be sourced to match your vehicle's exact heated-wire configuration. Installation is straightforward, though the technician will confirm the heating element is functioning correctly after fitting. No calibration is required for this feature.
Heating elements embedded in the glass melt ice from your wipers and the bottom of your windscreen.
A heated wiper rest area uses electric heating elements embedded into the windscreen in the area where your wipers park when not in use. These elements warm the glass to prevent ice and frost from bonding to the wiper blades and the lower windscreen edge during cold weather. This reduces the effort needed to clear ice in the morning and helps protect your wipers from damage caused by frozen adhesion to the glass.
Check your windscreen's lower edge where the wipers rest — you may see faint heating lines or elements visible in the glass. Your handbook or service history will confirm the feature. You can also ask your dealer or service centre whether your vehicle is equipped with a heated wiper rest area.
When replacing a windscreen with a heated wiper rest area, the replacement glass must include the heating elements. Aftermarket and OE glazing suppliers offer this feature, but availability varies by vehicle. The heating system does not require calibration after replacement, though the technician will ensure the heating element connections are properly restored during installation.
A Head-Up Display projects your speed, navigation cues and key alerts onto the windscreen so you can read them without looking down.
A Head-Up Display (HUD) projects driving information — speed, navigation cues, ADAS alerts — onto the windscreen in your line of sight, so you can read it without taking your eyes off the road. The projector is mounted in the dashboard and shines the image upwards onto a special HUD-compatible windscreen that uses a wedge-shaped laminate to prevent a ghost image. The image typically appears to float a few feet ahead of the car. Common on premium and sports models, increasingly standard on mid-range cars from the 2020s onwards.
Check your vehicle's specification sheet or handbook under 'display features' or 'HUD'. Look for a small projector unit mounted on the dashboard, typically below the steering wheel or in the instrument cluster area. When you start the vehicle, a bright image should appear on the lower windscreen area. Your dealer's service centre can confirm whether your specific model and trim level includes a HUD.
Your replacement windscreen needs to be HUD-compatible — built with the correct wedge laminate so the projected image stays sharp and double-free. Once the HUD-compatible glass is fitted, the projector itself typically doesn't need recalibration: image position is user-adjustable via your dashboard controls. We confirm your vehicle uses the HUD-compatible windscreen variant when ordering, so the replacement matches the original.
Your wipers automatically activate when rain falls on the windscreen.
A rain sensor is a device mounted on or behind the windscreen that detects moisture and triggers the wiper system automatically. The sensor uses infrared light to measure water droplets on the glass surface and signals the vehicle's electrical system to engage the wipers without driver input. This feature improves safety in sudden downpours and reduces driver workload in variable weather conditions.
Check your windscreen for a small sensor unit, usually mounted near the top centre behind the glass or at the base of the mirror. Look for a small dark component or lens. If your vehicle has automatic wipers that activate without you toggling the stalk, you have a rain sensor. Ask your dealer or service centre to confirm; they can check your vehicle records or wiper module settings.
Rain sensors are non-structural elements and do not require recalibration after windscreen replacement. The sensor bracket or mounting may need careful removal and reinstallation to ensure it sits correctly behind the new glass. If the sensor itself is damaged during removal, a replacement unit may be needed. Your fitter will confirm the condition and refit or replace the sensor as part of the standard replacement procedure.
Heated zones around sensors prevent frost and moisture buildup, helping your safety systems work reliably.
A sensor heated zone is an electrical heating element integrated into or around camera, radar, or sensor mounts on the windscreen. Its purpose is to prevent frost, ice, condensation, and moisture accumulation on sensor lenses and housings. This keeps safety systems — such as lane-keeping assist, collision warning, and adaptive cruise control — functioning accurately in cold, wet, or foggy conditions. Without this heating, moisture or ice can obscure sensors and cause them to malfunction or deactivate.
Check your vehicle's handbook for mention of 'heated sensor zone' or 'sensor heating' in the windscreen or ADAS section. Look at the top edge of your windscreen where cameras or radar modules are mounted — you may see small heating elements or wiring near these components. Ask your dealership or service centre directly: they can confirm whether your specific model includes sensor heating as standard.
Windscreens with heated sensor zones require careful handling during replacement to preserve the heating element and its electrical connections. The heating circuit must be reconnected properly after the new glass is fitted. Depending on the vehicle, this may involve static or dynamic camera calibration after installation. We confirm the exact procedure — including any calibration needs — when we look up your vehicle details.
Static calibration uses printed targets indoors to align your forward-facing camera after windscreen replacement.
Static camera calibration is a procedure in which a forward-facing camera system is realigned using printed target boards positioned at manufacturer-specified distances and heights in front of the vehicle. The vehicle remains stationary indoors throughout. A diagnostic tool reads the camera's view of these targets and adjusts the camera's alignment to factory specification. This ensures the camera can accurately detect road features, lane markings, pedestrians, and other objects — critical for driver-assistance systems like lane-keeping, collision warning, and adaptive cruise control to function safely and reliably.
Check your vehicle's handbook or ask your dealer's service centre whether your car has a forward-facing camera system that requires calibration after windscreen replacement. Look for driver-assistance features like lane-keeping assist, autonomous emergency braking, or adaptive cruise control on the dashboard menu. If your vehicle manual mentions 'camera calibration' or 'static target calibration', static calibration is likely part of your windscreen replacement service.
When a windscreen with an integrated or bracket-mounted camera is replaced, the camera's alignment can shift. Static calibration realigns the camera using indoor target boards, which must be performed in a workshop environment where printed targets can be positioned and secured at precise distances. This procedure is conducted after the windscreen is fitted and bonded. The workshop booking accommodates the additional time required for calibration, and we apply the no-split policy — both replacement and calibration happen at the same location on the same visit.
Dual cameras mounted near the rear-view mirror provide advanced driver-assistance features like collision avoidance and lane-keeping.
A stereo camera is a pair of cameras mounted in the upper windscreen area, typically embedded in or near the rear-view mirror housing. These cameras work together to capture depth information, allowing the vehicle's safety and driver-assistance systems to detect obstacles, measure distances, recognise lane markings, and monitor road signs. Stereo cameras are central to modern collision-avoidance, adaptive cruise control, lane-keeping assistance, and pedestrian-detection systems. Unlike single cameras, the dual-lens setup provides three-dimensional awareness, enabling more accurate decision-making by the vehicle's control modules.
Look in the dark area of the windscreen near the top, directly above or slightly offset from the rear-view mirror. You will see two small lens housings — typically circular or oval — separated by a small gap. Some vehicles display a camera symbol on the dashboard or in the instrument cluster when the system is active. Your vehicle's handbook or service centre can confirm the presence and type of camera system if you're uncertain.
Stereo cameras are bracket-mounted to the windscreen frame and require careful removal and reinstallation during replacement. The camera alignment is critical for safe operation — even small deviations can impair collision detection and lane-keeping accuracy. After windscreen replacement, your vehicle's camera system may require static or dynamic calibration depending on the specific make and model. We confirm the exact calibration procedure and schedule when we look up your vehicle. Calibration ensures the dual lenses are precisely aligned and the depth-sensing algorithms function correctly.
A printed VIN reference box along the bottom edge of your windscreen helps identify your vehicle's chassis number at a glance.
A VIN (Vehicle Identification Number) notch is a small printed or etched box positioned along the lower edge of the windscreen that displays your vehicle's chassis number. This reference marking is a manufacturing and administrative feature, allowing quick visual identification of the vehicle without needing to consult documents. It's particularly useful for service records, insurance claims, and vehicle registration purposes. The notch itself doesn't affect the structural integrity or safety performance of the glass.
Look along the bottom edge of your windscreen — typically in one of the lower corners — for a small rectangular box containing printed digits or characters. If you're uncertain, check your vehicle's service handbook or ask your dealership or service centre to confirm whether your model includes this feature.
When your windscreen is replaced, the new glass will retain the VIN notch printed or etched by the manufacturer. This is a standard feature on replacement windscreens for compatible vehicles and requires no additional work or adjustment. The notch does not affect glass fitting, cure time, or any post-replacement calibration procedures.
The Mercedes GLS is a full-size luxury SUV that arrived in 2019 and continues in production today, offering a commanding driving position and high-tech interior. All current variants in our catalogue feature advanced windscreen technology including acoustic glass for noise reduction, heated zones for sensor protection, and full ADAS capability with stereo camera systems.
Your GLS windscreen integrates multiple safety and comfort features: a forward-facing stereo camera for lane-keeping and collision warning, heated elements across the glass and wiper rest area, rain sensor for automatic wipers, and a head-up display projection surface. The acoustic interlayer reduces road noise while the green tint is standard across the range.
After replacement, static camera calibration is a required specialist procedure to restore ADAS function — this is carried out indoors at a workshop with precision alignment targets, ensuring your lane-keep assist and forward-collision warning work safely.
