FAQ

▍Q:How should I install 2mil Violet Glow Side Window Film without damaging the color layer?

A:Use lower heat settings during shrinking and avoid over-stretching. The 2mil film conforms well to curved glass, but consistent squeegee pressure prevents optical distortion.

If a defect appears, our after-sales team responds within 24–48 hours.

This ensures you can offer a reliable 8-year warranty and maintain your reputation as a supplier of premium window films.

▍Q: Is 22% VLT legal for side windows, and how does this film balance UV protection with heat rejection?

A: 22% VLT is legal for side and rear windows in most regions, but not for front windshields or front side windows in many areas. It delivers 99% UVR for outstanding UV protection, while 90% IRR provides strong heat rejection. This film is ideal for customers who want privacy, style, and performance on rear windows.
