Know Your Film

Understanding Window Tint

A little knowledge goes a long way. Here are the terms that matter most when you pick your tint.

What VLT Means

Simply put, VLT is how much light gets through the glass. The lower the number, the darker the tint.

VLT stands for Visible Light Transmission, the percentage of light that passes through the film and glass. A lower VLT number means a darker tint. A 5% VLT limo tint lets very little light through, while a 70% tint is nearly clear. Most states measure front side windows by VLT, so the number matters for staying legal as much as for the look you want.

Infrared (IR) Heat Rejection

Simply put, infrared is the heat you feel coming through a window, and IR rejection is how much of it the film stops.

Infrared is the part of sunlight you feel as heat on your skin. IR heat rejection measures how much of that heat the film blocks before it reaches your cabin. Ceramic and ceramic IR films reject far more infrared than standard dyed or carbon film, which is why a light ceramic tint can keep your car cooler than a much darker cheap film. More IR rejection means a cooler seat and less strain on your AC.

Setting It Straight

Window Tint Myths, Busted

A lot of what people believe about tint is out of date. Here is the reality on the three we hear most.

01

Myth: Tint Is Only About Looks

Reality. The right film blocks 99% of UV, rejects real heat, and cuts glare, so it protects your skin and interior every drive.

02

Myth: All Tint Is the Same

Reality. Cheap dyed film fades purple and bubbles. Carbon and ceramic films hold their color and reject far more heat.

03

Myth: Tint Ruins Visibility at Night

Reality. A legal shade installed by a pro keeps night visibility clear and actually reduces blinding headlight glare.

Stay Street Legal

Massachusetts Tint Laws

The number is how much light still gets through the glass. A lower number means a darker window. Massachusetts sets the darkest you are allowed to go, so anything lighter than the number is legal.

Notes: Massachusetts holds every window to more than 35% light, front and back, and it makes no difference whether you drive a car, an SUV or a van. Film may not be more than 35% reflective, and dual side mirrors are required if the back window is tinted. Medical exemptions are available through the Registry of Motor Vehicles. Fines run up to $250, and a third conviction carries a 90 day license suspension.
