Factory Tint vs Aftermarket Tint — What’s the Difference?

If you’ve ever wondered why your vehicle’s rear windows look slightly darker from the factory while the front windows don’t, you’re already seeing the difference between factory tint and aftermarket tint.

At It’s aWrap in Mississauga, we’re often asked by GTA drivers whether upgrading to aftermarket tint is worth it — or if the factory shade already does the job.
Let’s break down what separates them, what each actually does, and why the right choice depends on performance, protection, and Ontario’s tint laws.

What Is Factory Tint?

Factory tint (often called “privacy glass”) is applied during the vehicle’s manufacturing process. Instead of a film, the glass itself is infused with a dark pigment.

Key Traits of Factory Tint

• Built directly into the glass

• Usually around 15%–25% visible light transmission (VLT)

• No heat or UV rejection layer

• Mostly for appearance and privacy, not protection

• Standard on SUVs, trucks, and vans for rear windows only

Factory tint looks dark — but it doesn’t block heat the way real window film does.

What Is Aftermarket Tint?

Aftermarket tint is a film professionally installed on the inside of the glass.
It can be added to both front and rear windows and comes in different performance levels — from dyed to ceramic film.

At It’s aWrap, we install high-performance window films from trusted premium brands known for durability and optical clarity.

Key Benefits

• Blocks up to 99% of harmful UV rays

• Significantly reduces heat and glare

• Adds shatter resistance

• Available in a variety of shades and styles

• Protects interiors from fading and cracking

Unlike factory tint, aftermarket tint actively protects both the car and its passengers.

Main Differences Between Factory and Aftermarket Tint

Real Ontario Example — Tesla Model Y Owner

A customer from Burlington brought in his Tesla Model Y, thinking the factory rear glass meant his car was “already tinted.”
After a few drives on summer days, he realized the cabin still overheated.

We installed ceramic tint on the front windows and matched the factory shade on the rears for a seamless look.

Result:

• Cabin temperatures dropped by over 10°C

• Glare reduction improved comfort instantly

• Visibility stayed clear, even at night

That’s the real-world difference aftermarket tint makes — especially in Ontario’s mix of hot summers and cold, bright winters.

Which Type of Tint Is Better for Ontario Drivers?

If You Want Appearance Only

Factory tint is fine if your goal is privacy in rear seats.

If You Want Real Protection

Aftermarket tint is the clear winner for:

• UV defense

• Heat rejection

• Energy efficiency

• Glare reduction

• Comfort

Ceramic tint performs best for daily commuters, EV drivers, and long-distance travellers in the GTA.

Ontario Tint Law Reminder

Ontario regulations currently allow:

• Front side windows: must let in 70%+ visible light

• Rear windows: any shade as dark as 5%

• Windshield tint: top 3 inches only (non-reflective) – known as Sun-Strip.

That means even with ceramic tint, you can stay legal while improving comfort.

If unsure, our team can help choose the perfect film that meets Ontario’s legal requirements.

Maintenance & Durability

Properly installed aftermarket tint lasts 10+ years with quality film.
Avoid ammonia-based cleaners and rough sponges — a soft microfiber cloth and mild tint-safe cleaner keep your windows pristine.
