Alternative - what about applying either white or other light colored body wrap film to the two windows? I'm here in the Sacramento Valley literally baking in a solar oven. Yesterday, we broke a lot of records and I had the R1S parked outside. I have the clip in sunshades - the ones with the reflective exterior which blocks 100% of the sun. The amount of heat still radiating above my head is frustrating through this shade. There is a layer of superheated air between the shade and roof glass and we can feel heat radiating downwards into the cabin.

As a starting point we have full ceramic tint on all the side glass - Llumar.

Tried an experiment yesterday to validate my top of head heat sensation...

Placed a flat thin dark (my hair is black and partly gray) cushion on the center console horizontally, out of the sun between the front seats facing the roof sunshade. Test took 3 hours 1 hour per trial truck driven and cooled between trials. Truck windshield pointed due north per the dash display. Ambient temperature about 109 to 113F.

A) Left the closed truck parked outside for one hour in full sun with the shades in place cushion temperature was 131 F. Upper shade surface temperature 141.

B) Removed sunshade, let the sun stream in on the seats and console pad temperature 137 F.

C) Placed a light-colored blanket on the outside of the roof over the glass 121 F.

Potential confounding factors:

1. Incident angle of light between trial A & C moved a bit from passenger biased to driver side biased but no more than 15 degrees.
2. Cooling cabin between trials - checked only as being "comfortable" to passengers and underlying console surface temperature (Ocean Coast) to 80 F with AC blasting.
3. Initial test A may be biased cooler as interior materials had best cool soak from long drive before test.
4. I tried to limit blanket coverage in trial #3 to the glass only but did cover the strip between the front and rear glass.

Findings:

1. Blocking visible light and infrared before the roof glass - like a real roof insulates best.
2. Re-radiation of infrared from either roof or sunshade is similar - validates the finding of some that tinting the roof doesn't have a significant subjective effect.
3. Cooling a hot truck down takes a while with the compressor roaring and takes a lot of energy! This experiment ran my battery down 13%.

Hypotheses:

1. The sunshade, despite blocking all the visible light, re-radiated infrared into the cabin from a layer of superheated air between the reflective fabric and roof glass. Noticeably reduces interior surface heating which likely accounts for the 4 F delta but not much better than the stock glass roof with Ocean Coast interior. Black or green interior may have different results.
2. The glass roof rejects transmission infrared and visible light well but the mass of glass itself heats up substantially and radiates a lot of heat into the cabin (my head feels hot like sitting in front of a wood stove).
3. Blocking light before it strikes and heats the mass of roof glass substantially lowers radiant heat into the cabin and also blocks interior surface heating - simulating a real roof closely.

Therefore, I'm thinking of using either white or yellow PPF wrap on the glass exterior to block heat. I believe there was another person who did this with a large perforated sticker. Anyone see any problems with this approach? I'm really tired of baking in the summer heat!

Just a quick comment on this.

There are 3 components to your vehicle inside temperature due to heat transfer:

1) Radiation
2) Convection
3) Conduction

The glass roof has 100% UV blocking (per Rivian) but not visible light, and by far the best thing you can do is to get a windshield sun shade while parked. Roof sun shade clearly helps but the windshield is the biggest radiation heat source if parked. If driving, its problematic and it is what it is.

Your vehicle exterior color has a huge impact on inside temperature as heat conducts from hot to cold. If you have a dark color (black, green, red, charcoal), versus light color (white, silver, light gray), it can make 10s of degrees difference on the interior temperature.

The last is convection. By cracking the window by just a half inch on all four windows will ventilate the hot interior air out and bring in cooler exterior air in to regulate temperature better. In a parked vehicle, the interior is ALWAYS hotter than the outside ambient temperature, even in the recored heat condition (e.g., inside = 140 deg, outside = 105 deg).

Just use overheat protection with AC and turn on the climate control couple of minutes before you return to the vehicle, including the seat cooler.

I have the EV Sportline panoramic sunroof shade and I like it a lot. I can set the temperature 1-2 degrees F higher in the car now, since there is less thermal radiation from the sunroof. I also have a Llumar 80 tint on the windshield which helps reduce thermal radiation a lot when I'm driving towards the sun. I'm going to add it to the front side windows soon.
Do you have the shade for the R1S? I just got mine in and it doesn’t appear to be wide enough. I watched the video on their site, tried flipping it 180 degrees, and still had no luck installing it.

I think @EV Sportline may have updated their sunshades with this latest batch because I noticed the reflective barrier is already installed unlike what you see on the videos online

I mean, perhaps it’s user error, but I could not get the sucker to stay in place and after doing a quick measurement it seemed too narrow.

Far from precise measurements on my part so I’m hoping I’m wrong.

You need to rotate it 90degrees or 180 degrees. The roof is not square even though it looks to be. I can tell by the gaps it’s needs rotated. Thx!

Thanks! That’s what I did but when I do it 180 it appears the window by the windshield is too wide and the back of the sunroof too narrow. I turned It 90 degrees and it’s obviously too wide and not long enough. I won’t say it’s not user error, very possible it is, but I tried all directions to no avail. I logged a ticket to get some help (also in ATL if it’s easier to drive by and see what I’m doing wrong)

I must say I see very little practical benefit from the glass roof. Perhaps from the back seat it looks cool, I wouldn’t know!
Given the choice i would have taken a “normal” roof with a sunroof.
The idea for an exterior roof covering makes sense.

I’m testing like 5 different panoramic sunshade suppliers for fitment / quality and performance.

if y’all can hang tight and precondition the cabin for now, I’ll have the best possible option available soon for sale.

I’m also working with a supplier to improve their fit / quality so hopefully I’ll eventually have a custom solution based on forum member feedback as we improve the current designs.

The sunshades are a game changer, they just need to be made a little better.

It's the glass itself that gets blazing hot, which is why tint on the inside does not help.

The glass is radiating the heat to the interior of the cabin, even though the IR is being blocked by the glass.

I think a white or silver exterior wrap would help a lot. A cover with an air gap would be best. A white or silver exterior wrap, with an interior insulating headliner would probably be perfect.

I suggested an aftermarket market for replacing the glass with not glass: https://www.rivianforums.com/forum/threads/aftermarket-replace-roof-glass-with-not-glass.28523/

If I park outside in South Florida, I have to start the AC 30 minutes before I get in to cool the roof glass, otherwise it's like a broiler radiating heat onto my head.

Local in ATL, yes come on by! That is a good idea. PM me and we can figure the best time!

Fixing technical things for simple folk
It took me multiple purchases to find the right one for my R1S. Complications included poor fitment, loose material when mounted, or difficultly keeping the screen attached. Many did not meet my expectations until I found one.

EVBase R1S Sunshade (Front & Rear)

The large sun shade fits perfectly. The screen is tight and retains a factory-like look. There is no seams that have light leaking through and no loose edges. Same with the rear. For the front shade, you’ll need a trim removal tool to open up the head liner so it snaps in place. It takes a bit to get it in there but it’s all worth it. Highly recommend and it also allows some light through which is a nice touch.

Gang - pulled one of our R1T shades from stock today - tested it. Fits like a glove, like it always has!

The #1 issue people have when the sides are 'bowed' is they have it in 180 degrees backwards. See the photo to get a better idea. Make SURE you have this curved section facing forward.
