How to Match Front Windows to Factory Rear Tint in Calgary

You bought a new SUV or Truck. The back windows are dark, but the front two are clear (fishbowl style). You want them to match. Here is the science of getting that seamless look.
Understanding VLT (Visible Light Transmission)
Tint is measured in VLT percentages—the amount of light that passes through. Lower number = Darker.
The Magic Number: 20%.
Almost every manufacturer (from Ford to BMW) dyes their rear privacy glass to approximately 18-22% VLT. To match the front driver and passenger windows to the rear, we install a 20% film.
The Tone Match
Matching darkness is easy. Matching color is hard. Some cheap films look brown or purple. XPEL Prime XR is engineered with a neutral black tone that perfectly mimics the charcoal hue of factory glass.
The "Double Tint" Strategy for Calgary Heat
What if you want heat rejection in the back, too? Since factory glass is just colored (not heat blocking), many clients choose to tint over the factory tint.
| Scenario | Front Tint | Rear Tint | Result |
|---|---|---|---|
| Match Only | 20% | None (Factory) | Uniform Look. Front blocks heat, rear stays hot. |
| Full Heat Block | 20% | 70% (Clear Ceramic) | Uniform Look. Whole car stays cool. |
| Limo Style | 20% | 20% (Double Layer) | Fronts are dark. Rears become 5% (Limo). |
Alberta Tint Legal Reminder
Remember, tinting front windows is technically illegal in Alberta (read more on laws). However, 20% is the standard choice for aesthetic matching. If you want heat rejection without the attention, we recommend 50% or 70% on the front.
