Tinted windows are graded by how much it reduces Visible Light Transference VLT.

What does vlt mean for windows. In simple terms the VLT is the percentage of light that the film allows to pass through. As can be expected this must be weighed against the SHGC since more light through a window also tends to mean more heat. Our 20 dark smoke film has a VLT of 20.

Car and truck factories typically provide tinting on rear windows. The VLT of window film is a crucial part in determining how much heat protection UV protection and security protection you will get. Does VOLT always means the same.

So when you see a window film being referred to as a percentage this is the VLT. VLT - Visible Light Transmittance VLT stands for visible light transmittance. Visual light transmission or VLT is the amount of visible light that passes through a lens.

What does VLT mean. VLR is a relationship between visible light and solar heat transmission referred to as luminous efficiency LE. VLT stands for visible light transmission.

For instance a lens with a VLT of 12 allows 12 of light to shine through and blocks 88 of it. The lower the U-factor the more energy-efficient the window. Based on your preference this determines how much light you want to enter.

A higher number indicates that more light passes through the glazing. Refer to the following on how to calculate the LE of your tint. This is why we need to know the difference between VLT and UV blocking.
