How to Check Window Tint Percentage at Home

Window tint percentage, or Visible Light Transmission (VLT), determines how much light passes through your windows. Checking it at home ensures compliance with local laws and optimal performance. Here’s how to measure it yourself:

1. Use a VLT Meter (Most Accurate)

  • Purchase a handheld VLT meter online.
  • Place the meter against your window in direct sunlight.
  • The device will display the tint percentage.

2. Check Manufacturer Documentation

3. DIY Light Test (Estimate Only)

  • Hold a bright flashlight behind the tinted window at night.
  • Place a white sheet of paper on the opposite side.
  • Compare the light intensity to an untinted window. Dimmer light = lower VLT.

Why Check Your Tint Percentage?

  • Legal Compliance: Many states, including California, enforce strict VLT laws.
  • Heat Reduction: Lower VLT tints block more heat. Upgrade to Sun Shield Window Tinting for maximum efficiency.
  • Privacy: Darker tints enhance security. Explore privacy window film for offices for discreet solutions.
