Does a Mercedes GLC Windshield Have an Infrared Coating?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
Yes. The 2023 Mercedes-Benz GLC-Class windshield in our records, FW06028GTYN, carries an infrared coating alongside acoustic glass. The coating is a microscopically thin metallic layer that rejects heat, and because it is metallic it blocks radio signals, so gaps are deliberately left in it for cameras, sensors and transponders.
What the 2023 GLC windshield carries
- Infrared coating — a microscopically thin metallic layer that reflects heat away from the cabin.
- Acoustic glass — a sound-damping interlayer that quiets the cabin at speed.
- Deliberate gaps in the coating for cameras, sensors and toll transponders.
- Part number FW06028GTYN, identified from the VIN.
What the infrared coating does
The coating is a metallic film so thin it is measured in microscopic layers, and its job is to reject infrared heat before it warms the cabin. Because that film is metal, it also blocks radio signals, which is why the manufacturer leaves deliberate gaps in it — openings where the camera, the sensors and a toll transponder can each see through. Those gaps have to be in the right places, or the camera ends up looking through metal and the calibration will not pass.
The 2023 GLC also carries a mono camera in our records, with a static calibration as the listed procedure. That means the camera work is shop work — the vehicle stationary, targets at measured distances on a level floor, controlled lighting — rather than a road drive. Knowing that before you book matters, because a static procedure cannot be finished on a driveway.
Glass that fits the opening but lacks the coating lets more heat through and has the gaps in the wrong places, so it is the wrong part even when it seals correctly. The coating is built into the laminate during manufacture, so it cannot be applied to plain glass afterwards. Matching the part from the VIN is the only way to keep both the heat rejection and the correct camera gaps.
The coating and the camera gaps travel together
On a 2023 GLC the infrared coating and the openings for the camera and sensors are both part of the glass specification. Glass without the coating not only lets more heat in — it also lacks the gaps in the right places, which can stop the camera calibration from passing. The correct part keeps both.
Questions about the Mercedes GLC infrared windshield
Can I see the infrared coating on my GLC windshield?
No. The metallic layer is inside the laminate and invisible to the eye. It is recorded against the part number, which is identified from the VIN. See why glass shops ask for your VIN.
Does the GLC camera need calibration after a windshield replacement?
Yes. The 2023 GLC carries a mono camera with a static calibration, which is shop work with targets on a level floor. The calibration is part of the job and quoted with the glass. See what windshield calibration is.
Will the coating affect my toll transponder?
It can, which is why the manufacturer leaves deliberate gaps in the metallic layer for transponders, cameras and sensors. The correct part has the gaps where the vehicle expects them, so reception is preserved.
