How Does Sunlight Affect the Inside of a Car And How Can Window Film Help?

Have you ever opened your car door on a hot summer day and felt like you’ve stepped into a furnace? That’s the power of sunlight and while the heat might go away after switching on the AC, the damage it causes inside your car can be permanent.

What Happens When Sunlight Enters Your Car?

When your car is parked in the sun, heat and UV rays (ultraviolet rays) pass through the windows and get trapped inside. The temperature can rise above 60°C, especially during Indian summers.

But the problem isn’t just the heat. The UV rays damage the car’s interior slowly but surely. Here's what they can do:

• Fade your dashboard and make it look dull.
• Crack your leather or vinyl seats.
• Make fabric seats lose colour.
• Damage electronics and screens.
• Make your car uncomfortable to sit in.

This is called sun damage to car interiors, and over time, it lowers your car’s value.

What Parts of Your Car Get Damaged by the Sun?

Let’s break it down simply:

• Dashboard – Turns faded, dry, and even cracks.
• Seats – Leather cracks, vinyl peels, and fabric fades.
• Steering wheel & gear knob – Feels extremely hot and gets rough over time.
• Electronic screens – Overheating can damage the screen or reduce brightness.

So, yes sunlight can fade your dashboard and ruin the car seats.

Old School Tricks to Protect Your Car (And Why They're Not Enough)

Most people try things like:

• Using a sunshade for the front glass
• Parking under a tree or in the shade
• Applying dashboard polish or conditioner

These help a little but only give temporary relief. Also, side windows still allow heat and UV rays inside.

If you want full protection, the smart and long term solution is window film.

What is Window Film and How Does It Work?

Window film is a thin layer of special material that’s applied to the inside of your car windows. Good quality films block:

• Up to 99% of UV rays
• Up to 70% of heat

This keeps your car’s interior cooler, safer, and looking new for longer.

Benefits of Using Window Film on Your Car

Here’s why you should definitely consider it:

• Protects your seats and dashboard
  – No more fading, cracking, or peeling due to sunlight.
• Reduces heat inside the car
  – Makes driving more comfortable, especially in the summer.
• Saves fuel
  – Less heat means you use the AC less, which saves fuel.
• Blocks harmful UV rays
  – Just like sunscreen protects your skin, film protects your car.
• Reduces glare while driving
  – Makes it safer and more comfortable to drive during the day.
• Adds privacy and safety
  – Outsiders can’t easily see inside, and in case of a glass break, the film holds it together.

How to Choose the Best Window Film for Your Car

When looking for the best car window film for UV protection, check for:

• UV protection – Should block at least 98% of UV rays.
• Heat rejection – Higher is better (above 50% is good).
• Legal VLT – In India, side windows must allow 50% light, and front/rear 70%.
• Brand reputation – Choose trusted brands Autozcrave.

Avoid cheap films. They fade fast and may peel or bubble in a few months.

Important: Get it Installed Professionally

Even the best window film won’t work if it’s installed poorly. A trained installer:

• Applies the film in a clean environment
• Cuts it perfectly for your glass
• Ensures no bubbles or dust are trapped
• Gives you a warranty card for future issues

Extra Tips to Keep Your Car Interior Safe from the Sun

Even with film, you can do a few more things:

• Use a sunshade for the front glass when parked
• Park in the shade when possible
• Use seat covers or dash covers
• Clean the interior regularly to remove dust and grime
• Apply leather conditioner every few months if you have leather seats

Final Thoughts

Sunlight can do more damage to your car than you think. Over time, it fades the interiors, cracks the seats, and makes your car uncomfortable and less valuable.

But there’s a simple and smart solution window film.

It gives your car the protection it deserves: from heat, UV rays, and daily wear. Whether you drive a hatchback in Hyderabad or an SUV in Surat, window film helps you stay cool and protect your investment.
