Quick answer: VLT stands for visible light transmission, the percentage of visible light that passes through your window and film together. A lower VLT means a darker window. In Nevada, front side windows must let in more than 35% of light, so a film must be chosen carefully to stay within the rules.
VLT explained
VLT is the share of visible light that gets through the glass and the film. A 70% VLT window is fairly light, while a 5% VLT window is almost black. Because the factory glass already blocks some light, a film's rated VLT is not the same as the final reading on your window.
VLT and Nevada law
Nevada limits how dark front side windows can be. Front side windows must let in more than 35% of light, and the rules also cover reflectivity, windshield tint, and medical exemptions. Back side and rear windows can be darker. Rules can change, so check current requirements with the Nevada DMV or NRS Chapter 484D before you tint.
How we check it
Our team measures the VLT on your windows before installation, when possible, and recommends film that keeps you within the rules. If you have a question about a specific window, ask us before we install it.
