Hi all,

I'm planning on having the ix tinted as soon as I get it next week.

I'm very concerned about UVa and UVb getting into the cabin.

Do I need to have the roof glass tinted too? If I set it to be cloudy, does that block the bad rays?

Thanks in advance,

Frank

My tint guy wouldn’t do it. Something about not covered by warranty due to the manufacturer being against it. And though I haven’t measured it with any kind of equipment, it’s gotta be 99.99999% UV filtered. I’m astounded by how little heat gets through. Different wavelengths, I know. Still good anecdotally. If you’re that worried about it, yes, the opaque mode should have you covered. Saw another post on here once upon a time (guy had a meter) saying the roof glass was good to go. I’m equally impressed with the windshield too, by the way.

 

Thank you

 

Even in "bright" mode, the roof glass lets substantially less light through than the Tesla roof on the Model 3 I owned.
The "cloudy" mode, dramatically more so.
I think it will feel effectively tinted.

 

Thank you

And a brief primer on non-ionizing radiation from the Sun. Ultraviolet (UV) radiation is essentially received on Earth in three forms (wavelengths) - UVA, UVB and UVC. UVC (200-280nm) is almost exclusively absorbed by our atmosphere, otherwise we'd all be air-fried. UVA and UVB hit the Earth's surface essentially unaltered. UVB (280-320nm - think sunburn) is virtually all absorbed by ordinary glass transparent to light. UVA (320-400nm - think skin cancer) is about 50-70% transmitted by ordinary glass. Some UVA will be blocked by the PDLC (Polymer Dispersed Liquid Crystal) layer in the sunroof, but not all. It's proprietary construction from BMW, and I haven't seen any actual measurements, but the sunroof does block quite a bit of heat (and some light) from the interior of the cabin. In the process of absorbing radiation, the glass will get warm, but the heat layer is localized mostly to the air proximal to the surface of the glass, and again is reduced by the rejection properties of the glass itself, depending on the glass and the wavelength energy. Tinting will help, both with heat rejection and blocking transmitted radiation, depending on the type of tint and the degree of tint. Tinting your sunroof 1) will not cause it to break, 2) is unrelated to your warranty, unless the glass is damaged by the detailer or BMW can show proximal cause, and 3) BMW has not stated in any written or verbal public communications or technical publications of which I'm aware that you should or should not tint your sunroof, as they have not with any other glass windows in your car.

If you want to leave your sunroof as-is, it provides a fair amount of protection both from heat (part of which is actually IR radiation) and light, but the total amount of UVA protection is unknown (at least by me), and the reduced visible light transmission is limited by the semi-opaque qualities of the PDLC - it seems visually to me to be about a 30-40 percent reduction, but that's a guess. If you decide to tint it, that will provide additional protection (up to almost 100%) from visible light, UVA and IR, again depending on the type and degree of tint. Pick a good detailer who stands behind their product, and do your research. PSA out.

WOW, thank you for all of that info.

I measured it with a little cheap QuantaDose light test card from Amazon. Basically nothing from the top, almost nothing from the front windshield. The Front side windows let in all the UV. The back factory tinted windows let in quite a lot.

My solution was to tint the side and rear windows (with the exception of the trunk window, since light really won't make its way to anyone from there - and i hate the reflections made by tint over the defroster lines).

I'm thinking maybe I should apply something to the windshield later - but what I measured on the card was far lower lower than UV index 1 card readings, so it has to be very small.

Do you have option S0358 on your car? That’s the windshield option. Would be interesting if that would make a difference.

 

Hi,
We live in sunny Abu Dhabi and have both a BMW iX and a Tesla Model 3 Perfromance.
We always get our car windows tinted here - due to the intense sunlight & heat. The Tesla was bought new last November and we had the side windows and glass roof above the driver tinted with a very good quality 50% tint - that is supposed to reject 99% UV.
The iX arrived just 2 weeks back and the dealer had an offer for free tinting but due to number of cars being delivered, had a backlog for the tinting - so ours will get done next week.
The difference between heat levels of the two glass roofs is incredible.
Even with the 50% high UV rejection tint on the Tesla roof - you feel the heat of the sun on your head and the glass is red hot to touch on the inside (I have now fitted an aftermarket blind to reduce the temperature effect).
By comparison, you hardly feel any heat coming down on you from the iX roof and the glass feels much cooler to touch - to the point that we don’t even bother to “close” the iX roof photochromically during the day and are now wondering whether to bother tinting the roof - when the other windows get tinted.
Cheers
Steve

 

I live in Vegas and sun is very intense. Took delivery August last year and never had an issue that would make me think about adding tint.

 

Was looking for windshield covers and found this site which seems to offer side window shades, back window shades, and sunroof shade for the IX. BMW iX Windshield SunShade 2022-2024
Have not purchased from them ever so no idea if they're good, but at least there's an option.

 

Also found this on Ali Express. looks like an electrostatic cover. www.aliexpress.us/item/3256805834165756.html

I am selling BMW IX glass roof shade on ebay, just search BMW IX glass roof shade, then you can find my listing! =)
