Car Window Tint Hong Kong
IR rejection, legal VLT limits and real pricing

Darker tint is not cooler tint. Cabin heat is driven by infrared rejection (IR) and total solar energy rejected (TSER), not by how dark the film looks. LETS GET WRAP fits GSWF Night Shade in seven shades from HIR05 to HIR85, so your windscreen can stay bright and still block heat while meeting Transport Department inspection limits.

  • GSWF Night Shade in seven shades, mixed front-to-rear
  • Chosen on IR and TSER data, not on how dark it looks
  • Windscreen shades that pass Transport Department checks
  • Dust-controlled bay, full door-card removal, wrapped edges

What actually makes tint cool the cabin: three numbers

Only three figures matter: VLT (visible light transmission — how dark and how legal), IR (infrared rejection — how hot the cabin feels) and TSER (total solar energy rejected — the best single measure of heat performance). A dark film can be poor at IR, and a near-clear film can be excellent.

Hong Kong sun is infrared-heavy, so we normally fit a high-VLT, high-IR film on the windscreen for night visibility, then step the doors and rear glass darker for privacy.

  • Higher VLT = clearer glass; windscreen must stay inspection-legal
  • IR rejection maps to how cool the cabin feels
  • Aim for TSER of 50% or higher
  • UV rejection should be 99% to protect leather and skin

Hong Kong rules: how dark can the windscreen and front doors go?

The Transport Department sets minimum light transmission for the windscreen and front side windows, and inspectors measure it with a VLT meter. Over-darkened front glass fails inspection and badly hurts night and wet-weather visibility.

Rear side glass and the rear screen are more relaxed. Before quoting we measure your factory glass, because privacy glass already carries a tint that stacks with the film.

How window tint is priced

Price depends on film grade, glass area (sedan, SUV, MPV) and whether the windscreen is done as a single seamless piece. The windscreen is the most technical panel because of its curvature and size, so it is usually quoted separately.

A full-car package is cheaper than panel-by-panel pricing, and can be bundled with paint protection film.

Choose the right window tint in four steps

  1. 1

    Define how you drive

    Mostly parked in the sun, long highway runs, or heavy night driving? Night drivers should keep the front glass light.

  2. 2

    Read IR and TSER, not shade names

    Ask for the film's VLT, IR, TSER and UV figures instead of talking only about percentages of darkness.

  3. 3

    Mix shades by position

    Light, high-IR film up front; darker on doors and rear glass for privacy, while keeping the car inspection-legal.

  4. 4

    Sample and confirm the warranty

    View real samples on a light box, then confirm warranty length and coverage for bubbling and fading.
