One number you might notice when looking for a window tint for your property is the VLT rating. The VLT is the Visible Light Transmission total. The value refers to a percentage of light that can be transmitted through the lens.
A higher VLT rating means that the window tint allows more light to move through. A lower number means that the less visible light is going to travel through. Therefore, the glass will appear darker due to the low VLT total.
But what VLT rating is ideal for your window tint? You’ll need to look at a few totals:
- A window that has not been tinted should have a VLT of about 90. This means that the window lets in more than enough light.
- A high-VLT option with a rating of 60 to 80 may work if you are in a place where the conditions are naturally overcast, or it snows regularly.
- A mid-range window tint can work with a rating of 25 to 60. The feature is ideal for places where the sunlight isn’t too intense, or you’ve got a place where trees or other buildings might partially obstruct the sun.
- A low-VLT choice has a rating from 5 to 20. Places with very little protection against the sun could benefit from such a model.
Your window tint has to be reviewed based on the VLT total on your tint. Review the conditions where you are to see what you could benefit from the most when finding something of use.
