Home / Window Tint
Carbon ceramic and nano ceramic window film, fitted by Polyshield installers. Choose a shade that suits your car and the rules where you live.
Ceramic film stops a share of the sun’s heat before it reaches you, so the car cools down faster and the air-con works less.
Blocks ultraviolet light through the side and rear glass, protecting skin on long drives and the cabin from fading.
Takes the harsh edge off low sun and bright reflections, so your eyes work less on long highway runs.
Darker rear shades keep passengers, tools and shopping out of view from outside.
Less sun on the dash, seats and trim means less fading and cracking over the years.
Both films are metal-free, so phone, GPS, radio and keyless entry work as they did before.
Pick a film, a shade and your state. You’ll see how dark it looks and where it can go on your car.



Illustration. Real shades vary with your glass.
Tint limits apply to the glass and film together, and factory glass already blocks some light. Rules can change and some vehicles have different limits, so check your state's official page.
Both are metal-free, hold their colour and come in all six shades. The difference is how much heat they stop at the same darkness.

Request a quote from a studio near you and settle the film and shade for each window.
The glass is deep-cleaned, and the film is shaped to each window and fitted on the inside of the glass.
Your installer lodges your Polyshield warranty, and your warranty number is emailed to you.
Keep the windows up for 3–5 days. Small water bubbles are normal and dry out over 2–4 weeks.
| Carbon Ceramic Window Tint | 10 years |
| Nano Ceramic Window Tint | Lifetime |

Visible Light Transmission is the share of visible light that passes through the window. A 70% film lets most light through. A 5% film lets very little through. The lower the number, the darker the tint. Tint laws are written in VLT, measured on the glass and film together.
Ultraviolet Rejection is the share of the sun’s UV light the film blocks. UV is what burns skin and fades dashboards and seats. UV blocking doesn’t depend on how dark the film is: a light film can block as much UV as a dark one.
Total Solar Energy Rejected is the share of all the sun’s energy (UV, visible light and infrared) that the film stops from coming into the car. It’s the best single number for comparing how much cooler a film keeps the cabin.
Infrared Rejection is how much infrared light, the part of sunlight you feel as heat, the film blocks. The number in brackets is the wavelength it was measured at: 940 nm is near infrared, 1400 nm is further into the infrared. Each is a single-point reading, so it usually looks higher than TSER. Use it to compare films, and TSER to judge overall heat.
SIRR is infrared rejection measured across a band of the infrared spectrum rather than at one wavelength, as stated on the film’s data sheet. Because it covers a range, it gives a fuller picture of infrared heat blocking than a single IRR reading.
In every state and territory, the front side windows must let through at least 35% of light. Windows behind the driver must let through at least 20% (15% in the Northern Territory). The windscreen can only have a band across the top. The limits apply to the glass and film together, and factory glass already blocks some light, so ask your installer which shade passes on your car.
Light and medium shades make little difference at night. Very dark shades on the rear glass make reversing harder in poorly lit places, so many drivers keep the darkest shades for the rear passenger windows only.
Purple, bubbling tint is usually cheap dyed film breaking down. Carbon and nano ceramic films hold their colour. Small water bubbles in the first 2–4 weeks are moisture drying out as the film cures.
Yes. Your installer removes the old film and adhesive before fitting new tint. Mention it when you request a quote, as it adds time to the job.
