Panoramic roof is not IRR.

Who knew Ford wasn't full of crap and not committing fraud ?

As President Reagan said, quoting an old Russian proverb, Trust but verify.

Or, for me, just because it can be fun to measure things, and think about how they work.

Last report on IR thoughts, and I think this will be a wrap for me. I know that a lot of this thread was just silliness, but I can say that I have never given this much thought to auto glass before.

I will list some numbers from today's sun test (some clouds passing through), but generally for IR about 1000 nm to 8000 nm, our own feel seems good enough. IR thermometer readings are good too, and probably are just as good on MME materials, with nothing more needed.

May 13, starting about 12:48, mostly sunny, some increasing clouds, outside air temp 16C (61F)

Black bags with sand, center temp with flat contact probe (some variation across bag, just used center):
Dash in sun 36.5C
Driver's seat in sun from side window 34.3
Center console armrest 26.2
rear seat 23.5

Then, just taking non-contact IR readings around the car was just as informative, if not more so than the black sand filled bags.

Dash in sun (sun through windshield) driver's side 40.9, center 41.5, right side 37.5
Driver's seat in sun (side window) 52.9, shade (from side window) 27.9
Rear seat driver's side 37.2 in sun (side window) 27.5 shade
Front passenger floor 18.5, front driver's floor 17.6

Car pointed W (E-W direction), sun Southish. A cloud may have passed during this snap shop, direct sun light on drivers seat was a strip on the side towards the side window.

Well it was 102 in Phx today and the heat coming in the glass roof was really bad, what will it be like when it is 115?? I think someone will come up with an insulated insert that fits somehow into the edge of the surrounding glass. Maybe Ford will!!

No-one who hasn't lived in southern AZ in the summer gets this. I have the Tesmanian cover on order and will have 3M ceramic IR film installed on the roof as soon as mine is delivered (build week 6/14 IB RWD-X)

PIcked up car from tinters , sides and back done. Roof as requested not done. Reason is that glass has coating on inside and removing tint will damage coating. Call three more tinters, said the same thing.

Not to reopen a thread that got way off-topic for a while (what good thread doesn't), but here's a video that got posted yesterday with some good tangible examples of IR being reflected from low-E glass compared to "regular" glass.



If you don't want to watch the whole thing, jump to the 12:11 mark. The Crookes Radiometer spins faster in response to IR... so rather than looking and comparing numbers, here's a good intuitive physical example showing the impact of low-E glass to IR.

Oh. Not good news. I thought that a heat blocking film added to the panorama roof would solve the heat concern, if that becomes a problem. Perhaps such film can be put on the outside , similar to mounting ppf? A cloth shade stretched across the interior is an ugly and clutzy solution—not a solution i would entertain.

would the tinting hold up on the outside? Interesting question thou....? Im sure it wouldnt be under warranty by 3M thou...?

I've spoken with Ron Heiser about the roof and windshield. His comment about the choice of IRR windshield and Low-E roof was "This combination does the job in terms of heat transmission into the interior of the vehicle." Based on my experience so far, including the South Florida sun, he's right!

I’m sure this is a dumb question - who’s Ron Heiser?

While I was not a fan of president reagan, that is one saying of his that I’ve taken to heart and repeatedly quoted over the years of my career. You’d be surprised how many times it’s saved me!

Ooohhhhh!!!!! I remember those being sold in gift shops on the Atlantic City boardwalk when I was a kid! I actually had one! It seemed magical!

He was the Mustang Mach E Chief Engineer through development and until March. He's now Ford's Director of Product Development Quality.

Director of Product Development Quality you say? I’m sure his ears must be BUZZING if he ever reads this forum ???

Apples to Apples? IRR refers to transmission of Infrared Wavelength Light.
UV refers to Ultra Violet Light. Completely different ends of the visible light spectrum.
Infrared is heat! Ultraviolet is not. So, IRR rating doesn't pertain to the harmful UV radiation most people are concerned about. Most glass cuts out UVB radiation (the most harmful). Tinting windows helps cut UVA. So I'm not worried about the sunroof.

in the sekurit info page on the comfort sky coating it says "skin and eye protection equal to sunglasses of category 4" https://www.saint-gobain-sekurit.co...ure/enabling-sustainable-mobility/comfortskyr

Interesting, I went all summer with the car in Phoenix without issue. The roof was hot to touch but I did not feel heat radiate through. I put tint on all windows except the pano roof. I definitely felt heat through side windows before I did that.

I guess it's subjective.
