Solar-Control and Heat-Reflective Windscreens Explained

Solar-Control and Heat-Reflective Windscreens Explained

Some cars come with a solar-control windscreen, designed to reflect part of the sun’s heat before it reaches the cabin. In a Sydney summer that can make a real difference to comfort — and it affects a few things when the glass is replaced.

What Solar-Control Glass Is

Solar-control or heat-reflective windscreens have an extra treatment, often a very thin metallic or infrared-reflective layer within the laminated glass, that reflects part of the sun’s heat. Other windscreens use a tinted interlayer that absorbs heat instead. Both are different from aftermarket tint film — see benefits of window tinting.

How to Tell If Yours Has It

• Look at the glass at an angle — a faint coloured sheen can be a sign.
• Check the marking in the corner of the glass and your vehicle specifications — see car glass markings explained.
• Look for a clear window or dotted area near the rear-view mirror, often left uncoated so signals can pass through.

Toll Tags, Phones and GPS

Metallic coatings can block radio signals. Cars with these windscreens usually have a designated area, often near the mirror, where toll tags work. If your tag stops beeping after a replacement, check where it is mounted — see toll tags and dashcams after a windscreen replacement.

Why the Replacement Should Match

If a solar-control windscreen is replaced with standard glass, the car is still safe, but the cabin may get hotter and the air conditioning will work harder. Matching the original keeps the car performing as intended. Giving us your registration or VIN helps us source the right glass. Windscreen replacement with Aussie AutoGlass starts from $330, depending on your vehicle.

Frequently Asked Questions

Is solar-control glass the same as tint?

No. It is built into the glass during manufacture. Tint film is applied afterwards.

Can I add tint to a solar-control windscreen?

Windscreen tinting is limited by law. See window tinting laws in NSW.

Does it affect my phone reception?

It can reduce signal slightly in some cars. Most phones work fine.

Does it cost more to replace?

Usually, yes, because the glass is more complex. We quote each vehicle individually.
