How do the film percentages work and what does VLT mean?
• A: The VLT (Visible Light Transmitted) means the amount of natural light that is transmitted through the glass and window film combination. This means a window film with a 35% VLT value will stop 35% of the natural light entering your car windows and allow in 65%. Therefore films with a lower VLT will transmit less light and therefore be darker and conversely films with a higher VLT will transmit more light and therefore be lighter.
