How much more heat does ceramic tint block than dyed?
Shade for shade, LLumar IRX ceramic keeps out 18 to 22 points more of the sun’s total energy than ATC dyed film, and nearly three times the infrared energy. Here are the four shades the shop sells, from LLumar’s performance data sheet (LL0116NAEN, 03/26):
| Shade sold | ATC TSER | IRX TSER | ATC IRER | IRX IRER |
|---|---|---|---|---|
| 5% | 44% | 62% | 22% | 60% |
| 15% | 40% | 59% | 22% | 61% |
| 35% | 35% | 54% | 22% | 60% |
| 50% | 28% | 50% | 22% | 60% |
TSER, total solar energy rejected, is the share of the sun’s energy, light and heat together, that the window keeps out. IRER, infrared energy rejection, looks only at the infrared part and counts what the film absorbs and re-radiates. LLumar measures both on 6 mm clear glass, so read them as a fair comparison between films rather than a reading from your own car.
The gap is widest at the light end. ATC’s IRER doesn’t move from shade to shade, and its TSER rises only because a darker film blocks more light. IRX holds about 60% infrared rejection at every shade. That’s why IRX 50, which lets 54% of daylight in, rejects more total solar energy (50%) than ATC 05 (44%), which lets in 5%. One honest caveat: IRX 50 measures a little darker than ATC 50, 54% against 60% VLT, and that accounts for part of the gap at that shade.
Who gets the most from ceramic tint in the Fraser Valley?
Anyone who spends long stretches in a car that sits or drives in the sun. Four kinds of driver stand out.
Long commutes and long summer days
At Abbotsford Airport, a short drive east of Langley, the ECCC 1981–2010 normals give July an average daily high of 24.0 °C and August 24.4 °C. Each of those months averages 25 to 26 days above 20 °C, and the thermometer passes 30 °C on 8.7 days in an average year. If your day includes an hour or more on Highway 1 in that sun, ceramic’s extra 18 to 22 points of TSER are working for the whole drive.
Black or dark interiors
Dark seats, dashboards and headliners absorb more of the sunlight that reaches them than light ones do. The less solar energy gets through the glass in the first place, the less there is for them to soak up.
Kids, and anyone else in the back seat
In BC, the windows you can legally tint are the ones next to a child seat. Ceramic on the rear doors and quarter glass does its most direct work for the people sitting beside it.
Drivers who want a light shade
At 50%, ATC rejects 28% of total solar energy and IRX rejects 50%. If you want a lighter look and real heat control, ceramic is how you get both.
When is dyed ATC the better buy?
When heat isn’t the problem you’re paying to solve. ATC makes more sense when:
- The car spends its days in a garage or parkade, and most drives are short.
- You want the 5% blackout look anyway: ATC 05 already rejects 44% of total solar energy and cuts glare by 94%.
- Privacy and appearance are the goal, and the budget is fixed.
UV isn’t a reason to pay more. LLumar rates every ATC and IRX shade at more than 99% UV protection from 300 to 380 nm. As the Skin Cancer Foundation points out, side and rear glass is tempered glass, “which does not block UVA rays effectively”, so either film is a real improvement there, and ceramic adds nothing on top. Signal isn’t a reason either: neither film contains metal. The LLumar ATC dyed film page has its full specs.
Does BC’s tint law change whether ceramic is worth it?
Yes, it narrows where the money goes. MVAR s. 7.05(8) permits film in three places only: rear side windows, the back window if both outside mirrors are fitted, and the windshield’s top 75 mm. So the ceramic you can legally add sits behind you: it cools the back of the cabin and whoever rides there, not the glass beside the driver’s head.
Some drivers put near-clear AIR ceramic on the windshield and front doors anyway, and the shop installs it on request. It isn’t road-legal in BC, however light the film. Mission RCMP lists $109 as the typical tint fine (traffic FAQs), and a Notice & Order can require the film off and the car inspected. The shop spells out that risk before you commit; whether front windows can be tinted in BC is covered on its own page.
On SUVs and pickups with factory privacy glass in the back, the legal glass is already dark. LLumar pitches its clear AIR film at exactly that glass, saying factory privacy glass gives style and privacy but little heat control (LLumar AIR). The LLumar AIR clear ceramic page covers that option.
What does ceramic tint cost compared with dyed?
Ceramic is priced as an upgrade on the dyed starting price. ATC sets the base: rear glass from $220 on a sports coupe, $240 on a sedan or pickup and $260 on a full-size SUV or wagon (window tint prices). IRX and AIR are quoted per package on top of that, so the extra cost scales with how many windows your vehicle has. Ask for the job priced in both films and you’ll see the gap in dollars before you choose.
How to decide, and what to book
Choose IRX if you drive a lot in summer, carry passengers in the back, have a dark interior, or want a light shade that still handles heat. Choose ATC if the car is garaged, the trips are short and the goal is the look. Either way the film is plotter-cut for your vehicle, carries a lifetime warranty on film and workmanship, and the job is usually done in a single day.
The LLumar IRX nano ceramic page has every IRX shade, ceramic window tint in Langley covers the service, and ceramic vs dyed window tint compares the two film types line by line. When you’re ready, the quote form gets you both prices.
