Inner Channel Tucking
Inner channel tucking is the technique of sliding film deeply into the upper window seal channel, ensuring the film stays in place when the window is rolled down and back up.
When a side window rolls down, the seal compresses against the glass. If film isn't tucked deeply enough, the seal grabs the film edge and pulls it loose over time.
Quality installations tuck the film 5–10 mm into the channel — far enough that normal seal motion doesn't catch the edge. Cheap installations skip this step or tuck too shallowly, leading to edge lift within months.
We test the roll-up/roll-down cycle on every tinted side window before releasing the car.
