Why the last had high IRR but kinda mid spec TSER?

Done my full car with 3M Crystalline with the great help from @dog999, good workmanship and top notch service. kudos

that's why im confused, the dealer told me tser just a figure, they don't have meter to test it, but IRR they can test for you

wanna give my 2 cents, going by logic, if wrong, i will edit/remove :

lets assume the numbers are correct, then there may be few possibilities:

1. the high IRR applies only to a narrow range within the infrared spectrum, the other IR spectrum may have weak rejection, therefore TSER is lower than expected.

2. high IRR covers wide range of infrared spectrum, but rejection of other heat components of "light" is weak, as TSER includes UV, visible light and infrared (and all of these cause heat too), therefore TSER is lower than expected.

3. IRR is high, if the film is absorptive type, most of the IR is absorbed, over a period of time, there is a cumulative of heat energy from prolonged intense IR absorption that film became a secondary source of heat, therefore TSER is lower than expected.

had 2 car with IRR 90% and 99%, the 90% IRR, the VLT follow JPJ spec, and even this, had a much bigger TSER.

Thank you so much for your support . Enjoy ur cool ride bro.

anyone heard about V-Zion tint? Recently my friend buy Kia Carnival which has an original tint (brand name V-Zion). He wanted to darken the tint for rear windows and rear windscreen to avoid prying eye on the car boot, and was offered 2 choice:

1) V-Zion, add-on darken layer, to VLT 20% (for rear windscreen, and rear windows), warranty 5 years.
2) Raytech, add-on darken layer on existing V-Zion tint, VLT 20% (for rear windscreen, and rear windows), warranty only 3 years.

Any comments of which choice to take? Price about the same but Raytech have more IRR/TSER data showed in their website. V-Zion has limited info.

Is it ok to darken the windows & rear windscreen to VLT 20% and not affecting visibility at night? The front windscreen and driver/front passenger tint will remain original tint (VLT 70%).

Rhinepro Black Beauty OK?

Thanks

getting more and more brands of tints surfaced.

Used rhinepro for almost 4 years. Cheap (got mine done for less than 1k)

Pros:
Good heat rejection, felt really cooling
My shop got quite good workmanship, no bubbles up till now
Cheap

Cons:
The 70vlt had a blue tint that i didn't like. Obstruct visibility during rain. I went back to shop, they say they never had anyone complain this issue. But nevertheless willing to redo for me. Since they say tint no issue, i also dun doubt them, i jz retint to 50%vlt (since all other windows are fine.) Not jpj compliant but ok la, better than poor visibility during rain (strong light dispersion)
Color fade really quickly. Mine is almost illegal type of dark esp at night. In 2 years, faded a lot. In 4 years, almost completely gone d
Heat rejection also will decrease, but not by alot. Maybe about 20-30% after 4 years.

Tser is just a figure on paper only. Check my siggy for raytech review

Faded? The heat rejection sure also like this

Yep but the heat rejection loss not that bad la. It's pretty clear now in terms of tint shade, but heat rejection wise definitely not as bad as not having tint. That I can confirm because my car had no tint initially. I drove without tint for a year and I remember vividly how hot the car is without tint. The cabin is never cool, only local areas where the aircond is blowing. When open door, the gust from outside is cooler. And the sunrays, it burns the skin. Am not feeling all of these currently.

Wa... Rhinepro also fade so fast... they selling near to 2K leh

what brand is this? naber heard before?

Thx for review, u using which series? Black beauty or Black Rescue

Black beauty
